espite improvements in physical infrastructure development in the country during the recent years, significant gap exists between demand and supply of critical infrastructure facilities. It has become a binding constraint on the rapid pace of economic progress. In an aim to mitigate this critical infrastructure gap, the government plans to revitalise its PPP or Public-Public Partnerships route of infrastructure development.

An overview of PPP model Globally PPP has been extensively used for years to improve public services or the management of public sector assets through private participation. In India too PPP has been encouraged to fill the infrastructure gap. It was conceptualised as a powerful tool to develop the Indian infrastructure to a world-class and to remove the

infrastructure deficiency in the country. Modernisation and restructuring of Mumbai, Delhi and Kolkata airports are some of the major successful examples of projects execution through PPP route. Development of Bangalore (now Bengaluru) and Hyderabad airports have only strengthened the PPPâ&#x20AC;&#x2122;s success claim. Adding more facts in this direction, Pankaj Udeshi, Asst. General Manager, Procurement, Supreme Infrastructure India Ltd. said, â&#x20AC;&#x153;While the government remains a major sponsor of the PPP project, the private partner or partners hold more than 51 per cent of the equity. Typically, a private sector consortium forms a special company called a special purpose vehicle (SPV) to build and maintain the asset. The consortium is usually set up with a contractor, a maintenance company 10

existing in our competitor countries as far as the population size, geographical location and economy is concerned. Currently, in India 46 PPP projects are under various stages of implementation in 33 cities at a total approved cost of ` 25,902.84 crore for infrastructure development in urban areas.”

and a lender. It is the SPV that signs the contract with the government and with subcontractors to build the facility and then maintain it. The private party provides a public service or project and assumes substantial financial, technical and operational risk in the project. The infrastructure available in India is very different from the infrastructure

Fall of PPP However, post 2008 economic slowdown, the PPP model could not make a successful come back. The global recession curtailed spending on large scale projects from all the fronts drastically. Availability of finance became a major concern. Experts say even the PPP participants were not geared up to counter sudden economic downturn. Commenting on this aspect Abhijit Gupta, Managing Director at CASE India said, “PPP model was aggressively pursued by a lot of private players at the beginning of last decade and it resulted in a rapid development of infrastructure pan India. However with the economic downturn in 2007-08, the time and cost overruns became extremely difficult to be handled by the private players. Delays in land and environmental clearances, high interest rates, limited avenues for long-term loans for large scale infrastructure projects compounded the situation further.” Preparing a comeback As funding of critical infrastructure projects remains a concern and private investment in this sector is still weak, there is an immediate need to encourage public investment. Commenting on this aspect Arun Banavali, Supply-Chain Specialist and Management Consultant said, “The new government has already created a roadmap for PPP projects by developing friendly relations with large countries like Japan, USA and Australia among others. Most of the finance will go towards large value infrastructure projects. The large projects belong the power sector, the transport sector, real estate sector and water projects. These large sized projects need to be completed within stipulated period of time which needs speedier construction

with the asking rate being very high. Also, there is a requirement for high end and sophisticated technology.” Speaking of the government’s new initiatives, Mr Gupta says, “With several debates on migration to an expansive EPC model, the stakeholders have broadly settled in for the PPP model only to re-ignite the infrastructure growth. To facilitate this, the government of India has taken set up a new institute called 3P India, with a corpus of ` 500 crore, aimed at a robust contract making with reduced rigidity and a grievance redressal mechanism. 3P India will lead the way in re-formatting PPP projects, including the existing Model Concession Agreements (MCAs), negotiations and re-negotiations.” Other than this, funding for long gestation infrastructure projects is being facilitated through the InvITs and REITs. With the India Infrastructure Project Development Fund (IIPDF), the developers will be able to raise loans with a repayment schedule as high as 25 years from the currently available 8-10 years offered by the infrastructure finance companies. The government has simplified municipal bond norms, to help them raise funds for urban infrastructure development. Further, 12

the current government’s plan to create a Bankruptcy Code, re-booting of PPP model, public contracts (resolution of disputes) bill are steps in the right direction. “Removal of hurdles in project clearances and implementation of growth oriented intentions shown by the central government, should definitely translate into tangible demand for construction equipment in FY2015-16 and beyond,” Mr Gupta adds.

Ratan Lal Kashyap, Vice President – Procurement at G R Infraprojects believes, “The government should be proactive in getting land acquisitions, environmental clearance, forest clearance, utility shifting so that concessionaires can progress and achieve mile stones in construction. Infrastructure Industry is facing severe cash crunch and most of the concessionaires blame the bad economic scenario. We are quite hopeful that government will have good fund allocations for future infrastructure projects. The lending rates from the bankers should be workable as the industry is suffering due to huge debts and high interest rates making business unviable. The road asset sales should be simplified where lenders and concessionaries can exit and have liquidity for business opportunities” “The government’s support in terms of finance, land acquisition, easy license procedure etc. will lead to growth of infrastructure,” Mr Udeshi observed.

Revitalising PPP and opportunities for CE industry The infrastructure sector in India is expecting extreme focus from the government for initiating policies that would ensure time-bound creation of world-class infrastructure in the country. For this purpose, the country needs around ` 26 lakh crore infrastructure finance till 2020. However, in the face of acute fiscal and other constraints, there is probably no way other than turning towards the private sector as a means of financing infrastructure development. At this juncture, PPP model in the current format is simply not the answer. Expert like Mr Kashyap opines, “Balance in the model concession agreements safeguards and mitigates the risk of investors. Proper policies should be framed for investors and concessionaries. The cost of the project should be calculated by the state bodies where ROI makes sense for investors.” Therefore, there is need to revitalise PPP to provide a level playing field for all stakeholders. Presenting the Union Budget 2015-16, Finance Minister

Arun Jaitley said, “It is no secret that the major slippage in the last decade has been on the infrastructure front. Our infrastructure does not match our growth ambitions. There is a pressing need to increase public investment.” He also stressed on the need to revitalise and realign the PPP mode of infrastructure development. The government has also set aside ` 1,000 crore for this purpose, he announced. Revitalising and increasing focus on PPP model will enhance fund flow in the infrastructure development spectrum. And execution of large-scale infrastructure projects such as airports, railways, metro rails, highways and bridges, ports, power plants, dams and water reservoir, and telecommunications offer tremendous opportunities for construction equipment makers. Thus, such steps by the government will help construction equipment manufacturers as it will increase the sale of mining equipment, hydraulic excavator, wheel loaders, backhoe loader, bull dozers, dumpers, tippers, graders, surface miners, cranes, etc. Construction equipment used for such mega projects could be tower crane, crawler crane, gantry crane, EOT crane etc. for lift and shift in construction projects. Similarly there are concrete equipment like large size batching plants, boom placers, concrete pumps, transit mixers, conveyors and pipeline to transport concrete of mass quantities, in record time. Today such specialised concrete pumps can be used to move concrete to 60th floor of the building or to move it horizontally to 1.6 kms at a stretch is available to meet the construction needs with great speed. These are made possible with the help of high technology concrete pumps, by the means of concrete chemicals technology, to meet required concrete mixed designs along with the use of specially designed pipelines. There are other types of construction equipment like pipe layers, concrete pavers, canal pavers, hotmix plants, bitumin pavers, which are a must for meeting the international quality standards of concrete roads, bitumin roads and water canals. n

RIGHT CONCRETING Design efficiency of concrete equipment is more than just substance

uch before the construction boom happened in early 2000’s, buildings were small in size. The boom in construction and demand for housing led to changes. Similarly, there was a growth in infrastructure with an increasing number of roads, bridges and highways being built across the country. The rise in construction activity led to a demand for better concrete equipment. This called for concrete equipment to be more efficient, long lasting and economical. Also, as better concrete equipment is being called for with augmented set of needs, it led to a change in the equipment. Concrete equipment now require an increased output along with several constraints like increased productivity, reduced downtime, cost efficiency, and fuel efficiency . The inclusion of design in concrete equipment was initially seen as being able to give an aesthetic sense to the equipment. However, this perception is changed and design became an important determinant given the type of constraints faced by concrete equipment. Today, design of concrete equipment speaks of its capacity and several other features. Design is not

limited to individual components but encompasses the entire equipment. This enables concrete equipment to perform more complex tasks. Manufacturers today focus on design of the equipment even though their primary focus remains on the application of the equipment.

Putzmeister’s new generation equipment: designed for optimum performance Several developments have happened on the front of R&D at the Putzmeister centres at both India and Germany. Putzmeister introduced a new range of eSmart concrete pumps . The new range of eSmart pumps comprises of four pumps, BSA 1404HD, BSA 1405HD, BSA 1405D, and BSA 1407. The latest eSmart machines come with HMI (Human Machine Interface) control panel have Ergonic Graphic Display (EGD) which allows the operator to determine operating status and diagnosing faults of the machine in real time. The EGD performance displays various parameters like pumping hours, concrete output, hydraulic oil temperature, fault diagnosis matrix, stroke counter, engine speed etc., which makes it possible to monitor the pump

continuously. This system reduces the restrictions in hydraulic oil flow; and as a result, the heat generation in this hydraulic system is minimised and thus saves recurring maintenance cost. The machines are designed for safety and safe operation. The RSA or the grill safety switch keeps the pump and agitator from working if the hopper grill is open, thus ensuring safety and avoiding accidents. The new Open Pump system (OPS) design will drastically reduce the operational costs. The eSmart machines are very efficient and have a high output besides being ecological and environmental friendly. The system reduces the restrictions in hydraulic oil flow, thereby minimising the generation of heat. This saves recurring maintenance cost. The Putzmeister stationary concrete pump BSA 1408HD is a very popular and reliable concrete pump for high rise projects. The stationary concrete pump has some phenomenal capabilities. The Putzmeister BSA 1408HD set a record with a 601M vertical pumping with single stage pumping for Burj Khalifa. This is a reflection of Putzmeister’s

PROCUREMENT GUIDELINES expertise in high rise pumping. Putzmeister’s stationary pumps are a specialised equipment to get the job done. In India, where high rise buildings are becoming commonplace in several cities, Putzmeister pumps offer single stage pumps that are most suitable. BSA 1408HD has some remarkable features which make it stand out. Some advantages which are attributable to the pump are as follows: The reduction in S-valve gives BSA 1408HD a longer life. It requires less maintenance, given environmental and climatic conditions in India. The Putzmeister pumps use Chrome cylinders which increases the

Putzmeister’s BSA 1408HD

life of the machine by 50 per cent. The S- valve has only 4 wear parts. It has better energy utilisation and no losses in pressure. The mixture is kept equally homogenous by an agitator motor. The safety switch is well protected.

Schwing Stetter’s new generation pumps: made for the ultimate experience Schwing Stetter has pioneered with India’s largest boom on a 4-axle Truck. Schwing Stetter redefines standards in the 40-metre class with its S43SX truckmounted concrete pump. Schwing RZ boom design combines the “Roll and Fold” boom with a Z-fold boom at the tip to offer 270 degree flexibility at the last boom section. The boom folding system also enables concreting work right up to the vehicle bumper. With an overall length of less than 12-metre on a standard chassis this compact boom package does not extend beyond the machines outlet. With the 270-degree Z-fold section at the tip of the boom, operators have

a myriad of options for placement while shooting concrete up to 42.3 metres vertically, and 38.1 metres horizontally. The S 43 SX has an unfolding height of 8.7 metres for those low overhead situations and a slewing range of 740 degrees to suit many job site requirements. Its pipeline is a full DN125 mm diameter. The S43 SX front outriggers extend along an arc, do not have to be swivelled or telescoped and can fit into even the smallest gaps at the construction site thanks to their low height that saves space and time. S43 SX outriggers are designed to be compact, with a fast set-up time. It requires an 8.3 metres outrigger spread (the spread is the same, front and rear) for maximum stability. The “Generation 3” concrete pump is a low-maintenance, 164 metre/hr unit that provides long, slow-stroking action. The all-hydraulic design utilises Schwing Big Rock Valve, promoting maximum filling efficiency of the material cylinders even with harsh mixes. An open circuit design provides continuous hydraulic

oil flow for fuel efficiency, filtration and cooling. The S 43 SX can do infrastructure work, light commercial projects and bridges. In conjunction with the DN-125 pipeline, contractors can perform highvolume pours or provide a slow delivery with infinite volume control. A 600 litres water tank on the unit helps with clean-up at the yard or on the job site. Consistently lightweight design makes this machine a universal and flexible long-boom pump - both for mediumsized operations in downtown urban areas and on large construction sites.

Ajax Fiori: leveraging the advantage of design efficient equipment In 1992, Ajax Fiori revolutionised the concreting industry in India by introducing Self Loading Mobile Concrete Mixers (SLCM) technology ARGO series product line. ARGO series SLCM from Ajax-Fiori are unique machines, from self- loading and weigh batching of aggregates to mixing to transporting to placing of concrete to the exacting standards demanded by the critical infrastructure projects, be it in irrigation, roads and building construction. Ajax Fiori’s concrete equipment

The salient features of Ajax-Fiori’s ARGO series Self Loading Mobile Concrete Mixers are: • Four wheel steering: For good manoeuvrability and flexibility. • Four wheel drive: Ideal to negotiate rough terrain conditions at site. • Short turning circle: Able to operate in narrow, restricted job sites. • Weigh batching: To ensure proper quality concrete. • Ergonomically placed controls: High operator comfort. • Drum swivel: Enabling concrete placement on-the-go in select applications • ARAI certified: Can be registered with RTO for plying on public roads. These SLCMs are currently available in 3 sizes: • 4 Cu.M drum version – ARGO 4000 • 2 Cu.M drum version – ARGO 2000. • 1 Cu.M drum version – ARGO 1000 Similarly in Batching Plant arena Ajax-Fiori pioneered the unique concept of self-loading batching plants through its Radius Lift Arm (RLA) series in the year 1998. These plants eliminate the need for any dedicated loading arrangement of aggregates. RLAs are simple to operate and offer lowest power consumption and operating costs in the industry. The plant has two 180 degree hydraulically actuated swivelling arms which scoop-in the aggregates from the ground, thus reducing the wastages to a large extent. This Batching plant comes with a reversible drum mixer which has unique mixing blades that ensures high homogeneity in the concrete mix. These plants are offered in 2 models, namely RLA 20 and AMBISON at rated output of 20 and 30 cubic metre / hour

HireMyMachine: a virtual marketplace for hiring construction equipment A virtual platform, where CE owners from anywhere in India can list their equipment to find the right buyers

iremymachine is a web portal, which can help the construction industry unlock its vast resource of construction equipment lying idle at yards and slowly turning into useless piece of metal or scrap. The construction industry in itself is passing through a very tough phase, and this idling is further breaking our economics, so we came up with the idea that people should give out their idle equipment for rent in their own terms. This can be done by individual owners as well as large construction companies who own multiple equipment. An individual business owner or company still believes in hiring out their equipment but the big companies don’t believe in letting out their equipment on hire owing to their company policies. Plants and machinery department of every company should be a profit oriented and willing to rent out their construction equipment rather than allowing it to sit idle in yards. Companies can list their CE on Hiremymachine. In this way, rental companies can have a bigger market presence. There are many large rental companies having all sort of small and large machinery available for rent. However, a small or mid-size contractor does not approach these large companies assuming their rates will be high and their terms stringent. By uploading photograph and details of

their machinery on the Hiremymachine portal these rental companies can break this boundary that exists. Buying of construction equipment has become easy as there is need to pay a small or zero down payment depending on the equipment and company credibility. Individuals and companies buy these expensive equipment without doing proper project calculations, and when these machineries get idle they are not able to pay the instalments, making banks vulnerable. Companies can get help from www.hiremymachine. com by uploading pictures and details of their idle equipment. Construction equipment are used by several people like farmers, residential plot owners, factory owners, warehouses and potentially every business that at anytime needs to use a CE. Banks can use Hiremymachine to sell the equipment which they have got back from defaulters. The portal makes great sense in terms of logistics. If a company in Delhi takes some work in a village in Andhra Pradesh, they don’t have to worry about hiring CE’s. Using Hiremymachine can give them construction equipment that is close to his place of work. To do business at this portal there should be a person demanding for a machine and a person has that particular machine. It reinforces the

We can start believing in hiring rather than purchasing new equipment every time. Girish Jaggi, CEO and Founder, Hire MY Machine

principle that to do business through this portal that only two people who know each other can do business. In India, as of now there is only 8-9 per cent hiring of equipment while in developed countries like Japan the hiring percentage is 88-90 per cent. “We can start believing in hiring rather than purchasing new equipment every time,” says Girish Jaggi, CEO and Founder, Hiremymachine. He adds, “This phenomenon will lead to competition, helping all concerned as consumers, machine owners, machine manufacturers, spares and service industry and all others who deal directly or indirectly with CE.” Hiremymachine is simple and user friendly. “The listing on the site is free. There is no fee or commission until you get any business. There is a onetime commission and we exchange the details and dates of the parties concerned,” Mr Jaggi informs. n

Inside View

Remove hurdles to ‘Make in India’ P V Ramdev, Managing Director at Everest Engineering Equipment outlines the bottlenecks that need to be removed for a successful ”Make in India” mission

e welcome the much awaited decision of “Make in India” concept and its sincere implementation in next 10 years. This was supposed to be done in 1980’s when China started this. Still we can achieve this if the new government is able to turn down several hurdles one by one. If we discuss about tower cranes and passenger hoist manufacturing, we are still following some other countries design standards. We do not have manufacturing plants suitable for this foreign design standards and sizes. So we have to import this raw material like angle steel, square tube etc. Therefore we have to start developing from the raw materials or we have standardised the design according to Indian standards and available materials in India. Similarly the tower crane mechanisms are still getting imported from China and other countries. At present India is a fabrication workshop with imported steel and mechanisms. To come out of it, we have to start developing our own design according to the Indian standard raw materials, own mechanism, own slew rings and own joystick controls. Even the multiple cam limit switches, crane duty multiple pole motors and forced cooling VFD motors are not available in India. The Bureau of Indian Standards does not have an updated design standard for tower crane and passenger hoist with latest technology. We do not have a specific safety standard for design, testing and using of such equipment. This indicates to start from the scratch.

Expectations of a manufacturer Govt. has to identify and set up manufacturing zones near the cities with proper availability of electricity, water, roads and a welcome approach from

the local bodies. To start manufacturing in India, we have to run behind several local bodies, state govt. offices and several central govt. offices. This lengthy procedure must be reduced. Availability of trained workforce is increased and meeting the current requirement. But a manufacturer has to take care of employees’ PF, PT, WC policy, welfare fund etc. with lot of split accounts and paper work. We expect a single window, single account and single paper to deal all payments related to an employee through latest software developed by govt. A manufacturer has to pass through Excise, local sales tax, central sales tax, LBT, Octroi, Income tax and TDS etc. These taxes altogether will come about 30 per cent on the equipment cost. The complications on each tax are so high and each manufacturer has to spend lot of man power, papers to manage this govt. taxes. If the govt. works seriously to reach single window single paper for all the above taxes through newly

developed software, then nobody can stop the pace of India. Over and above, a manufacturer has another 30 – 35 per cent expenses for transportations, advertisement, sales, service, warranty parts, distributor commissions etc. So we can image at what price the customer can get this equipment! The settlement of economical offences does not have any time frame in India. It can be life-long and the accused will attain his life span without any recovery and/or punishment. Now the govt. has to change the law and specify the exact time frame for the settlement and/or punishment of economical offence like 6 months to 1 year maximum. Quick response and decisions are another requirement to succeed “Make in India”. n

What is your take on the recent performance of EOT cranes industry in India? The crane industry in India is highly fragmented. Its expected market growth in the range of 10 â&#x20AC;&#x201C; 12 per cent between 2010 and 2015 on account of global slowdown and cascaded effect in India the industry has seen many investment plans being deferred. By revenue, about 70 per cent of the market is held by the established players. The manufacturing sectorâ&#x20AC;&#x2122;s average growth was around 7.7 per cent in 2009-10. In 2007-08 it peaked to 14.3 per cent. The decline is due to the slowdown in GDP in 2011-12. In the past 2 years, there were not much of improvements in many policies around infrastructure, land acquisition and environmental clearance. However, with the new government in the centre, things are looking up. According to estimates, the Indian industrial cranes market approximately amounts to ` 2,000 - ` 2,200 crore per annum. Majorly 70 per cent demand comes from the private sector and the remaining 30 per cent from the government-owned companies. The future prospects for crane sector looks promising, due to the growth of manufacturing sector, infrastructure development and foreign direct investments in India. The demand for industrial cranes is expected to grow steadily at a pace of around 20 per cent every year and would help India grow and place itself amongst the fast developing

Wirtgen opens new plant in Pune, plans for further expansion

We want to grow our manufacturing base in India, want to get more products and increase our sales and service representation Stefan Wirtgen, President, Wirtgen Group

he Wirtgen Group, one of the global market leaders in mobile road building and road rehabilitation technologies, recently completed 20 years of operations in India. This milestone was celebrated by inviting over 1,000 customers and partners to visit the Pune plant to witness the technology day and the official opening of their new plant for crushing and screening equipment on 27th March. The plant was inaugurated by Stefan Wirtgen, President of the Wirtgen Group and Ramesh Palagiri, Managing Director and CEO, Wirtgen India. As a part of celebrating its Technology Day, Wirtgen showcased its entire product range of machines for the road and mineral technologies. A live demo for over one hour was also organised to display the technologies such as cold milling, cold recycling, asphalt paving, compaction and also crushing and screening where new generation machines were in operation. The event also marked the roll out of the first Kleemann Screen produced in India and also the 1,000th Hamm Compactor from the plant.

Optimistic about Indian market Speaking of the growth opportunities in India, Mr Wirtgen said, “Our job is to continuously grow in India. We consider India as an important market for us, and it is a fascinating country full of opportunities. Therefore, we want to grow our manufacturing base in India, want to get more products and increase our sales and service representation. So we are here for a long term future.”

Glimpses of Wirtgen’s technology day

Wirtgen also wants to be a part of the government’s “Make in India” initiative. Commenting on this, Mr Wirtgen said, “We are very happy with the government’s ‘Make in India’ initiative and positive about the campaign. India will grow tremendously in the next few years and we want to be a small but important part of it.” Speaking of the feedback the group has received from the Indian market during the past year, Mr Wirtgen said, “We have received a positive feedback, our turnover rose; even though the market was flat in the past years. But then we are here for long term and we see a great future. Our focus is to support our customers with better service and to create new and innovative products.” Commenting on the current scenario for road building equipment market, Mr Palagiri said, “We expect a lot of tenders to come from building of roads in the Northeast part of India. In the last 4 months there has been growth in the road sector and EPC projects in India. There is around 20 per cent growth primarily because 5,000 EPC jobs have been awarded. We are going to target our existing customers using our compactors and city contractors.”

the Kleemann screens, initially for the Indian market. In Germany, we produce the higher capacity screens, but most of the other screens will now be produced in India not only for the domestic market but for export as well. In the same plant, we will have production of Vogele jaw and cone crushers for which the design work has just started. We expect the first machine to roll out in 12-18 months time. The design process is being done jointly in India and Germany. The same process what we did for Hamm products and Vogele pavers which will roll out by next March-April.” Wirtgen Group has invested about ` 80 crore for the new plant, while its total investment in India is about ` 180

Increasing localisation Speaking on the Wirtgen India’s

Industry Update business focus, Mr Palagiri said, “Wirtgen maintains its focus on making Crushers with a capacity of 200- to 300-tonne, both jaw and cone crushers. These products will offer standard quality at competitive price for the Indian market.” Wirtgen has adopted the product for the Indian market like using a local Cummins engine and also adopted all the new technologies. It is also planning to do the same for Vogele pavers, which is going to be launched by the same time next year. Mr Palagiri added, “The wheeled and the tract pavers will have 6-metre width to meet the specific requirement for the state highway jobs in India, where they are trying to convert single lane into double lane. For the screens, we will have a range from 200-600 tonnes.”

Technology shift The market size for this class of pavers is roughly around 300 machines now. Wirtgen is expecting about 30 per cent market share. In future, the company also

looks for exports for the same range of products. “If we look at the world market, road building equipment category is getting divided based on the engine regulation and not much on technology,” explained Mr Palagiri. “We have US, Europe, Australia and Japan with Tier 4, while the rest of the world with Tier 2 or Tier 3. But most of the Tier 2 countries are gradually shifting to Tier 3. So the products that we are going to develop in India, except the screens, will be for Tier 3. With that we have a chance to export to any market in any Tier 3 countries.” Wirtgen has displayed many new technologies like milling of the road. People just keep on doing layers, dig it out, throw it and put their layers. Now Wirtgen machines are capable of removing the aggregates, and there is tremendous saving of natural resources and cost. “The only additional cost what the contractors incurred is adding the extra bitumen which gets oxidised, mixing cost and the relaying cost,” shared Mr Palagiri. “Otherwise, the cost

Advantage

Steel Buildings Leading industry-experts talk about the enormous advantages that steel buildings offer

steel building is a metal structure fabricated with steel for the internal support. Steel provides several advantages over other building materials. Steel buildings are simple in design, easy to construct, light weight and designing time is significantly reduced compared to the conventional buildings.

Advantages of using steel buildings Construction has evolved continuously over the years. From natural habitat, the choice of materials has evolved from thatch, to mud, then stone, later concrete, and now steel. There have been other options also along the way, some of which are still in use. Today, use of steel in construction is not limited to providing structural strength. For a wide range of buildings, construction practices are moving from ‘steel in buildings’ to ‘buildings in steel’. “The principal drivers for this shift are time and cost. Compared to conventional materials, buildings in steel can be completed faster and cheaper,” comments Rohit Ranjan, General Manager Marketing at Tata BlueScope Building Solutions. “Since steel buildings are lighter, there is lesser demand on foundation design as well. Also, the inherent properties of steel allow for greater design flexibility.” He adds, “The advantage of faster building completion is that building owners can start generating revenues faster, earn profits sooner, and improve returns on investment. If starting operations sooner is not the priority, building owners can manage their cash flows better. They can push-back spend, without adversely affecting project time-lines, and consequently business operations.” Some advantages outlined by I V Ramana Raju, Senior General Manager – Sales & Marketing, Pennar Engineered Building Systems Ltd. are as follows: • High strength to weight ratio: Weight of the structure made of steel will be less resulting in less member sizes and foundations • Uniformity in strength: Properties of steel do not change as opposed to concrete • Ductility: Steel can withstand extensive deformation without failure under high reversal of stresses especially in the case of earthquakes • Toughness: Steel has both strength and ductility • Additions to existing structures: New bays or entire new wings can be added to existing frame buildings and steel bridges may easily be widened

• Ability to span long distance: Steel is good for clear/ longer span. With steel, providing column less space is much economical than RCC • Faster occupancy: With PEB’s, one can save 20 to 25 per cent time in construction for industrial buildings and around 40 per cent for multi-storeyed buildings. Early occupancy generates early returns • Cost efficiency: Optimised design results in less usage of steel and cost • Flexibility of expansion: PEB’s are easy to expand or modify in future • Low maintenance: PEB’s need very minimal maintenance • Earthquake and hurricane resistant: PEB’s are designed to take care of earthquake/hurricane impact • Single-source responsibility: In PEB’s, responsibility starting from design till erection lies in single hand, hence no hassle of multiple agencies • Factory controlled quality: From raw material till finish, at every stage, quality is controlled thoroughly • Re-locatable: PEB buildings can be dismantled and reerected at other locations. • Quality: Quality building is achieved as all fabrications happen inside controlled factory environment by use of advance welding machines.

Explaining the prime advantages of steel buildings, Anjan Dutta Roy, Vice President, Tiger Steel Engineering India Pvt. Ltd. said, “Steel building weights are generally less compare to RCC, hence the earthquake force affecting the building will be reduced at the same ratio. Steel is 18 times more ductile than RCC which ensures energy absorption when exposed to deformation beyond the flexibility behaviour, this feature gains importance under dynamic loads.” According to Mr Roy, benefits of using steel buildings are: • Earlier possession of the building provides faster ROI • Large unsupported spans • Steel construction allows slender columns resulting in

maximising floor area • Advantages include excellent strength to weight ratio resulting in lower foundation costs • Economic methods for shaping and curving • PEB allow off-site manufacture resulting in less site activity • Bolted and connections are generally exposed and therefore are simple to check for quality • Steel buildings can be relocated or recycled once its use has been overtaken by events. The concept of steel buildings gained impetus in the Indian markets in the early 2000 and the usage of steel and especially steel is growing very rapidly in the Indian construction industry. According to D Raju, Managing Director at Kirby Building Systems India Ltd., in 2000, when Kirby Building Systems India Ltd. started its operations in India, PEB concept was not well known in the country. Today Kirby Building Systems India Ltd. has a capacity of 200,000 MT per annum with Hyderabad and Haridwar each having an annual capacity of 100,000 MT respectively. “Changes in government regulations, industry friendly policies and promotion of India as preferred FDI destination also resulted in heavy FDI inflows thereby giving a further boost to the PEB technology,” Mr D Raju said.

Arvind Nanda, Founder Director and CEO, Interarch Building Products Pvt. Ltd. says “Pre-engineered steel structures are not just eco-friendly, but also profitable in the long run. The structures are made of 100 per cent steel which is recyclable up to 90 per cent, this saves primary resources and reduces waste hence saves energy”. “The structure by Interarch Building Products Pvt. Ltd. help in reducing the carbon footprint by reducing the solid waste, improving air and waste quality and conserving natural resources by reducing the rate of consumption,” Mr Nanda claims.

Materials used and applications Material used for building steel structures is known as mild steel which is immensely strong. Mr Ranjan shares some interesting points as follows: • Use of insulation, double skins, high reflectivity paints and a host of other design elements, make steel buildings suitable for almost all applications. Skylights, louvers, vents, etc. reduce spend on artificial lighting, ventilation and environment control. • There is no mixing or preparation required at site, hence limited disturbance to local flora. This makes steel buildings ‘greener’ as well. • Steel is the preferred material for all prefab structures and PEB

use steel which is more than 80 per cent recyclable. • Building owners can choose from a wide range of profiles for roof and wall cladding. “Standing seam profiles, like the MR-24 roof system offered by Tata BlueScope Building Solutions, perform the best on leakage prevention. This helps protect machines and materials in the building, and allows uninterrupted work,” Mr Ranjan adds. Some of the main PEB applications include factories, warehouses, workshops, showrooms, petrol stations, site offices, supermarkets, aircraft hangars, cold storages, metro stations, shipyards, sport stadiums, offices, etc. “In current scenario, anyone planning to put up a factory or a warehouse

Challenges Experts believe that the perception about steel buildings being costlier is only a notion as the industry has grown by more than 15 to 20 per cent during the first decade of this century. This growth is in itself shows that these structures are not very expensive but slightly costlier than concrete structures. However, Mr D Raju reveals, “One of the main challenges faced by the PEB industry in India include acceptance among the Indian corporate which is still moderate when compared to developed economies.” Comparisons between steel and concrete buildings will always exist. Commenting on this aspect, Mr Roy said, “One important principle where concrete can challenge steel is the time duration between the completed design drawings and the fabrication of structural steel components. It is up to the steel detailer or fabricator to speed up this process. But in construction site concrete can never compete with steel either structural reliability or construction time.”

Conclusion Construction contributes to more than 66 per cent of total steel consumption and in advanced countries more than two-third of the buildings are made in steel. The government should promote steel as construction material for speedy implementation of the projects and avoid cost overruns and project delays. Experts observed that there is almost no risk of error on the steel frame members that are manufactured and controlled at factory and that can be assembled very easily. By using structural steel in the load bearing system, various geometrical forms can be designed, which is not possible with other materials. Also, as components of steel buildings are manufactured in a controlled environment, quality of steel buildings is typically better.

Steel is 18 times more ductile than RCC which ensures energy absorption when exposed to deformation beyond the flexibility behaviour. Anjan Dutta Roy, Vice President, Tiger Steel Engineering India Pvt. Ltd.

However, designers and engineers need to understand fabrication methods, and should try to fit their work to the fabrications facilities available. The more the designers knows about the problems, tolerance, and clearances in shop and field the more probable it is that reasonable, practical and economical designs will be produced. n

Mr Berglund believes that India represent the most dynamic among the traditional BRIC nations. He confidently says, “India in the next 3-5 years will represent the largest geographic opportunity available for Trimble. We hope that about 10 per cent of our revenue will be coming from India in the coming years, i.e. around $250 million. India represents significant geographic opportunities simply because the momentum in India is stronger than corporate traditional BRIC.” There is a very good map between Trimble and Indian ambitions where Trimble can provide a significant contribution. Trimble from the sense of cultural stand points to look at the Indian market and other markets from inside out. “Our product base today matches the needs of the market very closely,” explains Mr Berglund. “If any agriculture product is not appropriate for India, we reinvent ourselves to some extent with the context of the market. It is a very good match between the Indian needs and Trimble’s capabilities.”

Trimble aims to play significant role relevant to smart cities concept. “Trimble group is fairly selective in targeting the roles we play,” says Mr Berglund. “We are a large provider of telematics. In terms of building the smart city and building the smart city intelligently, intelligent construction is our primary territory.” There are a number of discrete areas where Trimble can provide significant capabilities in smart cities with intelligent transportation systems. In order to have an intelligent transportation system, there is a need to have knowledge at micro level. There is a need to understand how things are in intelligent transportation. “In terms of capability, Trimble is a participant in the smart city initiative,” claims Mr Berglund. “We will demonstrate the appropriate flexibility in bringing solutions.” n

Adhesives

Henkel pioneered anaerobic adhesives in the 1950’s and is one of the global leaders in adhesives, sealants and surface treatment solutions

Anaerobic Adhesives: Liquid engineering for manufacturing and maintenance

ypically used to augment the seal or holding force of a mechanically joined assembly, anaerobic adhesives are used as threadlockers, thread sealants, retaining materials, and flange sealants. When designed into an assembly, these adhesives reduce component inventories, decrease total manufacturing costs, enhance equipment reliability, and minimise aftermarket breakdown and associated warrantee problems. By definition, anaerobic adhesives remain liquid until isolated from oxygen in the presence of metal ions, such as iron or copper. For example, when an anaerobic adhesive is sealed between a nut and a bolt on a threaded assembly, it rapidly “cures” or hardens to form a tough crosslinked plastic with tenacious adhesion to many metals. Though anaerobic applications differ widely, in most cases the adhesive provides high shear strength. • When used to lock threaded assemblies together, anaerobic adhesives prevent loosening and corrosion of the fastener, maintain proper clamping force, and offer controlled torque for removal of the assembly. • For rigid cylindrical assemblies, such as joining a bearing onto a shaft, anaerobic adhesives known

as retaining compounds enable manufacturers to bond parts that once could only be assembled using press fits or shrink fits. • Anaerobic gasketing materials are widely used as formed-in-place gaskets that produce leak-proof seals between mating flanges, preventing leakage of moisture, gasses, fluids, or contaminants. Anaerobic adhesives fixture in minutes at room temperature and fully cure within 24 hours. Full cure of anaerobic adhesives may be achieved more rapidly using short-term exposure to heat (e.g. 30 minutes at 120 C). In assemblies where a liquid primer or activator is required to accelerate cure, the primer is applied to one or both fastener surfaces before the adhesive is applied. No mixing of components is required. As an anaerobic adhesive cures in a threadlocking application, it forms polymer chains that find their way into every tiny imperfection in the threads. Thread friction increases with the application of threadlockers due to interfacial connections to the surface roughness of the metal. The adhesive completely fills the microscopic gaps between interfacing threads to positively lock and seal threaded assemblies, preventing lateral

movement and protecting the joint from corrosion that can result from moisture, gasses, and fluids. A typical nut and bolt assembly has as little as 15 per cent metal-tometal contact. Just a few drops of liquid threadlocker fills the remaining air voids between the thread roots and then cures to a thermoset plastic which provides a 100 per cent unitised assembly until the user wants it to come apart. These adhesives offer high torque strength, good temperature resistance, rapid cure, easy dispensing, and good vibration resistance. Threadlockers are available in low, medium, and high strength formulations. Most threadlockers are colour coded for strength, with purple and blue representing low and medium strength grades, and green and red representing high strength grades. However, no threadlockers are permanent; the low and medium strength grades can be disassembled with common hand tools at room temperature, and the high strength threadlockers can be removed following direct exposure to 450 F temperatures. The strength and viscosity of the adhesive needed for an application are directly related to the size of the fastener used. Low strength threadlockers are 42

Adhesives 40

Technology

used on screws up to ¼ inch in diameter. Medium strength materials are for fasteners up to ¾ inch in diameter. High strength threadlockers are best used on fasteners up to one inch in diameter found in permanent assembly applications. Low viscosity penetrating threadlocking formulations are also available that easily wick into preassembled fasteners up to ½ inch in diameter. In applying threadlocking adhesives, the adhesive must wet the total length of the thread engagement area. Proper wetting is dependent on the size of the thread, the viscosity of the adhesive and the geometry of the parts. If the parts are large, then wetting both faces provides the necessary reliability for adequate adhesive application. For through-hole nut and bolt assemblies, threadlocker should be applied only where the nut and bolt will meet when the assembly is fully tightened, as only adhesive between the threads will cure (Fig. 2). For blind hole assemblies

such as cap screws, threadlockers should be applied to both the bolt and into the bottom of the hole (Fig. 3). If adhesive is applied only to the bolt, air pressure will force the liquid threadlocker to escape as the bolt is torqued down, resulting in insufficient amount of threadlocker and possible assembly failure. The greatest challenges faced with traditional anaerobic adhesives have been: • Promoting cure on a wide range of metallic and non-metallic substrates that may be contaminated with grease or oil • Long-term exposure to elevated temperatures greater than 300 F • Long-term exposure to high levels of mechanical stress. New surface insensitive threadlocking formulations have been developed to be forgiving of oily and contaminated surfaces, curing in spite of residues that would inhibit cure of traditional threadlocking adhesives. In addition, these threadlockers are

also designed to cure more easily on passive or inactive substrates such as plated or annodised surfaces, reducing applications where primers are needed. While traditional threadlocking adhesives can withstand only limited temperatures (–65 F to +300 F), new anaerobic adhesives that incorporate innovative chemical technology have been formulated to maintain their integrity at temperatures up to 400 F. These products are ideal for applications that endure extreme thermal cycling, such as automotive and aerospace assemblies. New toughened formulations have also been developed to provide better overall performance under extreme thermal and mechanical stress. As these materials are tougher than traditional anaerobics, they are less impact sensitive and can withstand prolonged exposure to intense vibration, rotational, shear and tensile forces.

Green doors and windows â&#x20AC;&#x201C; an accepted modern necessity Green doors and windows can achieve energy efficiency when factors like like material efficiency and thermal insulation are fulfilled

oors and windows are of significant when it comes to being energy efficient and having the material efficiency suited for the geography of the place and the climate of the region. Green doors and windows are essentially the doors and windows that have the material efficiency and the energy efficiency. They are suited to fulfil global norms while being able to provide energy efficiency and material efficiency. There are several factors that have transformed doors and windows today. Scarcity of spaces and demand for housing has led to increase in cost of land prices challenged by affordability and market conditions. Windows and doors became an important part of housing, in terms of ventilation and in determining the temperature between indoor and outdoor environment. Global as well as domestic factors have been determinants of the doors and windows

we use in residents and offices. Glazing efficiency of the glass doors as well as enhanced material efficiency led to people using better alternatives to simple glass windows. However, this is more true for the new constructions. uPVC and other materials are used on a large scale today in modern housing and construction as they are considered a better alternative. The thermal efficiency of windows is important in places which have extreme weather conditions, either hot or cold. Since centuries, doors and windows have been a part of places inhabited by people. Every culture and form of architecture has its own type of door and window. It is a tradition to use wooden doors and window frames in many cultures. However, wooden window frames and wooden doors are today being replaced by metal window frames and metal doors.

In places in India where power cuts are a problem; people opt for windows that are energy efficient. In colder areas too, material efficiency of doors and windows contribute to the warmth inside the structure. Doors and

windows can be helpful in their own way irrespective of the climate of the region.

Green Doors and windows are an important part of energy profile of a building Architect Surinder Bahga shares a compelling point on the status of Green doors and windows. He says, “In the designing and construction of green buildings different building components like materials, roof, facade, etc. have their significant roles. Similarly, doors and windows play their own distinctive part in the energy profile of the building. The major intake of heat in a structure takes place from its windows and doors only. Therefore, their positioning, designing and material choice is important in making the building sustainable.” Speaking of the design aspect to improve the energy efficiency of windows, Ar Bahga says, “The designing of the windows and doors are highly engineered in order to optimise their energy performance. Although there is an emergence of new technologies, a few false trends are also gaining hype like installation of huge glass windows. I would say that these are highly unsustainable. Due to the construction of large glass windows, a lot of heat starts entering inside the building. To counter that heat we then install heavy air-conditioning units. If we need large

Rajesh Chawla, Director, VEKA India has some interesting points to share on making doors and windows energy efficient. He says, “The one basic criteria to make windows and doors energy efficient is to have minimal heat loss from a window or door area. So, there a couple of factors that one needs to keep in mind while making such a module. Several factors are involved, for example to choose for the Lowest ‘U’ value profiles material, Low ‘U’ value of glass, appropriate fabrication of frames and sashes where welded joints - as in uPVC windows, are preferred choice, min twin sealing gaskets system, multipoint locking fittings etc. After a window with high quality standards is fabricated the same needs to be installed in a quality way so that the gaps between the window frames and the wall do not become heat leakage areas resulting in heat losses.”

Material efficiency of Doors and windows Speaking of material efficiency, Mr Chawla says, “One need to choose a material that not only has a low ‘U’ value and helps in reduction of heal loss etc. but to consider a material which, while in the manufacturing process, also used lesser energy or other resources like water etc. Here, uPVC profiles fares far better as uPVC profiles extrusion therefore the energy consumed is approximately 60 per cent lesser than aluminium and no water contamination is made. Further, the material is also recyclable and for this process too consumes much lesser energy. Further, to make the uPVC more environmental friendly, one needs to consider the Lead free uPVC profiles” Suggesting the use of bamboo for material efficiency, Ar Bahga says, “Bamboo is structurally stronger than

steel and at the same time light weight and easily workable. India has the second largest cultivation of bamboo in the world. It can be fashioned aesthetically to make doors and windows.” Speaking of sustainability, Ar Bahga says, “Any building can be made sustainable with just a slight amount of effort and thought, resulting in a healthier environment for all of us to live in.”

Designer green doors and windows With the real estate boom, designer doors and windows are becoming popular. The design of Windows and Doors is changing because of changing consumer tastes. Designer homes are being bought by well to do, as well as the affluent people who prefer artistic interiors. This zeal is also translated to green designer doors and windows. Designer doors and windows are being used in the luxury home segment as well as by people who choose to have them. Therefore, energy efficient designer doors and windows are also a good alternative for people in India. Since, the home décor is an important part of the rendering of modern homes, designer green doors and windows have their place. Some creative people prefer designer doors and windows. They may also prefer a combination of both creativity and energy efficiency of the doors and windows in their homes. From an architectural point of view, designer green doors and windows have their own significance. Internationally, designer green doors and windows are made keeping in mind the aesthetics and local culture. Despite being energy efficient and having material efficiency, doors and windows can look traditional and have a look like they are from a different era. In this way, people are able to express their culture, history and society while having the advantage of being energy efficient or green. People irrespective of their culture in several countries choose to express themselves and their personalities in this manner. n

Turn over a new leaf There is an urgent need for reforms in door manufacturing in India ndia is a unique country which utilises timber batton infill in the flush and skin doors; a primitive process, discarded globally many decades back. We must say goodbye to our obsession for timber filled doors. You may be aware that the concept of recycling wood scrap as an infill in doors is no more a reality as the saw mill operations are getting smaller with reduction of timber availability and on the other hand there is an explosion of construction due the rise in housing needs all over India. More than 12 lac trees every year are required to feed the infill needs of over 100 lac doors each year. Realizing, the bare facts and non-sustainable practices other countries have already switched to eco-friendly infill boards like the tubular boards which are 100 per cent made from recycled wood wastes. We should also change. It is too late already.

K-Lite unveils solar street light

-Lite Industries, a unit of Kumbhat Group and one of the leading manufacturers of lighting fixtures in India, has launched solar street lighting system with LED (light-emitting diode) luminaire â&#x20AC;&#x201C; a green concept for a greener world. The product has been developed in the backdrop of rising concerns to save the mother earth from the ill effects of carbon emission in the electricity generation using conventional fuel and avoidance of mercury in the manufacture of electric lamps. The solar street lighting system consists of a solar panel with photovoltaic (PV) cells that converts the solar energy into electrical energy. The resulting electrical energy is stored in a battery through a solar charge controller. LED Lighting fixture operates directly from the DC battery. Decorative pole, of any height and in a wide range according to aesthetic requirement, by itself can house the solar panel, luminaire, and the control gear box with battery.

B2B Purchase

April 2015

K-Lite claims that the life of the solar panel is 20 years. The wattage rating of the panel and the battery capacity (Ampere hours) depends on the factors such as street light wattage required, number of hours it is to burn and the autonomy (otherwise known as the reserve days) for which energy has to be stored as a backup. For instance, for a 20-watt LED luminaire to burn for 8 hours during night and with two reserve days as back-up, a 12-volt battery of capacity 120 AHr and a solar panel of 100 Wp is required. The lifespan of the LED source is nearly 50,000 burning hours as against around 5,000 to 10,000 hours of conventional sources such as metal halide/high pressure lamps and 50 times that of GLS (general lighting service) lamps. To obtain the same light output, the power consumption of LED luminaire is just one-tenth of what is required for a conventional GLS lamp. Though the investment on the entire system is higher upfront, long-term benefits due to the

energy saving, longer lifespan, lesser maintenance, social and environmental benefits, outweigh. The complete solar lighting system costs from around ` 20,000 (with 3-watt LED) and goes up to ` 2 lakh (with 80-watt LED). The dealers of K-Lite, spread across the country and globally in UK and USA, make the product available to its customers of various locations. n

We try to restore the original capacity of the structure with the help of a technology known as FRP composites. Dr. Gopal Rai, Chief Executive Officer Dhirendra Group of Companies

How is the construction chemical market going on right now? The construction chemical market is doing well. People need to be educated in this field for better knowledge; otherwise there would be more success and less failure. The construction chemical industry is growing Year-on-Year at a rate of 15 to 20 per cent. In order to increase growth, people need to be educated about the technology. The Chryso event, organized by IIT Bombay is an important step towards educating people. What is your role in this industry? At Dhirendra Group of Companies, we take up rehabilitation of projects, which involves structural rehabilitation of major projects like airports-bridges, road-bridges etc. We increase the capacity of the structure, because every time a structure cannot be demolished. We try to restore the original capacity of the structure with the help of a technology known as FRP composites. My PhD at the IIT Bombay was based on this. Now, this research has been carried forward by the industry and one of the company’s ventures recently achieved the ‘Vishwakarma’ award for the same. What are your future plans? Right now, we are working with railways and they have a lot of structures which have to be retained for the next 20 to 30 years. Using this technology we give a boost. Now, we try to repair everything in 20 to 30 days, what used to earlier take about 6 to 7 months. It is 7 times faster now and we save time without disturbing the road traffic or air traffic. This technology is growing and can become a landmark technology.

Are there any technology to get a view of a construction site from far? Yes, there is the new technology wherein cameras are used for capturing images of construction sites. Nowadays, the bridges are so far that the amount of sensors can’t be measured and cannot be noticed by bare eyes. The new technology, known as photoscreening will help click pictures. From a long distance, we have to focus on the specimen which has to be checked. So when you focus the camera in a static state, you take one film and take another image under a distressed state when a truck or any vehicle is moving. Once the picture is clicked and there you have a different pattern. By observing the change in pattern, one can understand the difference between what deflection is and what is distressed. So it has improved the understanding and the study of what is deflection and distressed. Could you share the Year-on -Year growth the industry should achieve to grow up? The industry needs to grow up with knowledge. If the people of the industry do not catch up with the industry growth have no knowledge, the industry will suffer. Therefore, we need to have more applications and more trained people. We should now embrace the Indian code, as till today we being Indians are not using any Indian code. The ACI are still silent about the Indian codes. So according to me, we should go through our guidelines. This is the seventh year I am practicing but till date, with the existing BIS code we are not able to meet our code. We need some guidelines as, if we do not get the guidelines, there could be misuse of this technology. n

Admixtures like Zentrament, and the Muraplast FK and Powerflow range of admixtures (plasticisers and superplasticisers) are especially designed for concretes requiring high early and final strengths. These are primarily high range water reducers, based on selected second and latest generation polymers, are free of chlorides and can be adjusted for slightly extended workability time. The concretes so produced are free from bleeding, segregation, are pumpable and require minimum compaction. These are suitable for use in the pre-stressed and precast industry for manufacturing elements such as beams, columns, slabs, railway sleepers, concrete piles, rails, posts, electrical poles, concrete pipes, etc. The development of strength is rapid enough to enable early stripping of moulds for rapid, economic construction on account of lesser formwork requirements. With the correct concrete technology and optimum use of Zentrament, Muraplast FK and Powerflow range of admixtures, about 15 to 20 per cent cement savings may be achieved by maintaining the same slump and strength.

The relationship of construction chemicals to the civil engineering industry is exactly like that of a pharmaceutical industry to human body. Today spurious integral waterproofing compounds, tile adhesives and tile joint fillers are being manufactured and sold in the market by the unorganised sector in such quantities that the organised sector can hardly catch up. Unfortunately this industry is without any support from civil engineering fraternity, architects, specifiers and the government. Because of non-recognition and lack of knowledge about the importance of this industry, every manufacturer is fighting his own battle with the Central Excise or Sales Tax departments, to explain the classification of his product, which is not easy anyway even for an engineer to understand. The time and energy which is thus wasted could be harnessed for constructive developmental works.

Industry initiative In an effort to safeguard their interest construction chemicals

manufacturers have finally been able to form an association which is CCMA (Construction Chemicals Manufacturers Association). This association under the leadership of its current president is in touch with various organisations like FICCI, BIS, architects associations, civil engineering associations etc. to get a deserved status for this industry from the government, removing bureaucratic hurdles faced by this industry. The sensitiveness of this industry, its utility in the construction and nation building, demands that it be treated slightly differently with other manufacturers and the government needs to simply support it.

About PERMA The growth factor and performance criteria for building products are expected to increase multi-fold in the 21st century. To bridge these gaps between performance expectation and the availability of quality construction chemicals, professionals with decades of experience in this field have joined hands to take up this challenge under the banner of “PERMA”. The product range of PERMA consists of polymer-based tile fixing adhesives and coloured joint fillers, range of waterproofing chemicals, integral waterproofing compounds for concrete and mortars, water repellent coatings, structural and non structural 56

Durability- enhancing concrete admixtures

ivil engineering is known as mother of all engineering branches. Construction and building material sciences is a highly matured technology, world over. What we build brick-bybrick, may get destroyed, drop-by-drop seepage of water. To avoid premature deterioration of the buildings and other concrete infrastructure facilities, a scientific approach towards waterproofing is essential to avoid leakages and seepage. Concrete does not always behave as we would like, some of the undesirable behaviour can be seen as disintegration, spalling, cracking, leakage, deflection and settlement. Durable concrete structures can be achieved only through careful attention to many details. Admixtures play an important role in todayâ&#x20AC;&#x2122;s concreting to get durable concrete structures.

Types of admixtures l Accelerating admixtures (ShaliPlast FS) l Retarding admixtures (ShaliPlast R) l Water reducing admixtures (ShaliPlast SP/PCE) l Air entraining admixtures (ShaliPlast AE) l Shotcrete admixture ( ShaliPlast Shortcrete P/L) l ShaliPlast LW+ /LW++ Advantages of various types of admixtures l Shortens the setting time of cement and therefore increases the rate of gain of strength l Improves workability, cohesion and extends setting time, provides protection against delays and stoppages and facilitates keeping workable concrete for extended period l In the large construction, good workability of the concrete throughout the placing period and prevention of cold joints is ensured by adding retarders in the concrete l Enables earlier release from precast moulds thus speeding guidelines

on use of admixtures in concrete production l Reduces segregation and increase density and compressive strength l Early use of concrete floors by accelerating the setting of concrete l Reduces water requirements, bleeding, shrinkage and time required for initial set.

Migratory corrosion inhibitor (ShaliPlast RCI), being amine based bipolar in nature, used as an additive during concreting or repairs, can protect the steel from corrosion in aggressive environment. Steel in reinforced concrete is prone to chemical attack in certain corrosive environments.

Dosage ranging from 0.06 to 3 per cent by weight of cement, different admixtures are recommended and a water reduction from 10 to 35 per cent or more is achieved. Admixtures help us achieve, a much more watertight concrete.

Conclusion In recent past, usage of concrete admixtures has increased, as the construction industry had grown on a sustainable basis. Concrete sections are getting thinner and hence require higher grade of concrete, which can be achieved only by use of admixtures.

General concrete deterioration Most concrete deterioration can be attributed to water penetration. Since concrete absorbs moisture until it becomes saturated. Moisture hastens deterioration not only because it promotes chemical reactions but also because it carries dissolved chemicals that can react with the steel, lime and other components in the concrete. It also plays a major role in concrete deterioration. As a result of water entering in to concrete results in spalling of concrete.

Secondary to the architecture of the building, the material used in the external coat has equal importance.

Appearance and weather protection Paints, waterproofing chemicals, weather guards and many more products dominate this market and the user has today wide choices to make. Paints may not always be able to achieve water proofing but provides great finish. Waterproofing chemicals will definitely do a good job in minimising the leakage, however they lack aesthetical appearance.

A good exterior finish has three main requirements: • Good foundation of consistent and good quality plastering. • Weather protection capacity. • Long lasting and low maintenance. With the latest technology, Walplast is able to provide products matching all the above requirements.

Plastering: A foundation to good exterior finish Exterior plastering acts as a foundation to the finishing and provides weather protection. Sand plays a major role in plastering. There are two types of sand available for the construction industry, natural sand and manufactured sand. Both have their pros and cons. Natural sand is found in riverbeds and is excellent for construction. However due to environmental reasons, it’s mining or dredging will soon have to be stopped. Manufactured sand is made from rock and has rough edges which make it difficult to deal with. There are certain chemical additives as well as equipment which take care of these edges and shape it up to a nice friendly and workable form. Plastering problems • Sand problems: Incorrect gradation, impurities, salt contain and excess water • Storage problems: Space constrain, pilferages etc. • Mixing problems: Errors at site (incorrect mixture of sand and cement)

Why waterproof underground structure in low water tables In order to enhance the durability it is essential to provide impermeable underground structures, explains Anil Kumar Varma, Executive Director at Kryton Buildmat Co. Pvt. Ltd.

structure is only as strong as its foundation and when water ingresses into these foundations it causes seepage and reduces the durability of the structure drastically. The ingress is judged not just in the current situation but also keeping in mind the future conditions. Waterproofing in wet areas of the structure such as toilets, kitchens and balconies is given due importance. However underground structures and foundations where water tables and rain impact is low, waterproofing is sidelined stating cost as a factor. But, today with prices of spaces skyrocketing, builders are optimising space to the maximum. There are more underground basements, car parking etc. being constructed across residential and commercial projects in the country. This is where water plays most havoc as it causes more damage to structures than earthquakes. So, in order to enhance the durability it is essential to provide impermeable underground structures. Even in areas with low water table and low rainfall, underground structures need to have a full proof waterproofing system, as surface water from rain percolates through the subsoil. Once it reaches the structure, water carrying harmful chemicals find its way to penetrate the structure. Not just the surface rain water, but there is always an eventuality of bursting water supply line, drainage pipeline etc. In such an eventuality there is high water pressure coming in contact with the structures, ending in leakage and dampness.

What’s the problem? What happens when adequate precaution and measures of waterproofing in underground structure is not taken from the very start? The remedy is more expensive and time consuming than the process of waterproofing during construction would have been. At times the repair cost becomes not only exorbitant but also non-workable. Keeping all of these facts in mind, builders, architects and consultants need to waterproof structures based on utility of the structures in all conditions.

A simple solution Crystalline technology comes as a solution that fits the needs of underground and overhead structures by reducing permeability and increasing durability. Normally, it is recommended that one should consider PRAH (Permeability Reducing Admixture for Hydrostatic) conditions because these permeability reducing admixtures can make structure impermeable even under water pressure as well. Kryton offers the most complete crystalline concrete waterproofing solution system available. As the pioneers of the crystalline waterproofing admixture, Kryton has refined an innovative system that includes the waterproofing admixture Krystol Internal Membrane (KIM), the Krystol crack repair system, and the Krystol surface-applied solutions. Kryton’s award-winning Krystol technology is by far unique in terms of not just its chemical properties, but also physical properties. This technology uses water as a catalyst to create long, narrow crystals within the concrete itself. These crystals permanently fill

the pores, capillaries and hairline cracks of the concrete mass, and continue to grow throughout the concrete, reaching lengths of many inches over time. Once the concrete has cured, the crystalline chemicals sit dormant until another dose of water (such as through a new crack) causes the chemical reaction to begin again. The ability to reactivate in the presence of water gives Krystoltreated concrete the ability to “selfseal”. When cracks form due to curing shrinkage, settling, seismic activity, etc., water entering through them causes new crystals to form and grow, blocking and filling the cracks. As a global company and one of the leaders in the crystalline admixture category, Kryton brings world-class, category-leading technical expertise, and tailors it to local applications. Kryton is a global company that also has the ability to act local. Being a subsidiary of Kryton, Kryton Buildmat Co. Pvt. Ltd. is governed by all the quality and manufacturing standards of the parent company. The company’s production unit is ISOcertified and Kryton claims to be the only crystalline concrete waterproofing supplier in India that holds the coveted ISI hallmark. Kryton brings over 40 years of international experience and has been present in India for 20 years. Kryton provides customers with high-quality products, manufactured to international standards, and back-up the product line with the unparalleled service and expertise.

Water Treatment

Technology

Moving towards zero discharge This article explains the advanced technologies that help in re-utilisation of waste water across industry

ater scarcity is a global problem that needs no introduction. With increasing population and pollution of surface and ground water sources, the problem is aggravated with each passing day. Indiscriminate industrial development and exploitation of limited water sources are compelling every industry to seriously address the problem. Availability of water itself has become a serious threat. Therefore industries are considering many options to reduce their water usage and to recycle water to the extent possible, including selection of manufacturing technologies which use minimum water and produce less waste water. As the cost of water increases, legislation becomes more stringent and enforcement stricter, water recycle becomes a very viable option. While recycling of waste water has gained significant popularity over the last decade because of the reasons mentioned above, elimination of the rejects or approaching zero discharge is still not a very viable proposition in many cases. It hence becomes necessary to identify avenues for recovering material/by-product from the effluent stream, thereby making it easier to treat, while also increasing the economic viability of such recycle proposal.

Total water management approach to recycle of waste water Waste water recycle should take shape at the drawing board stage in contrast to the traditional approach of designing the raw water and waste water treatment plants (end of pipe solutions) separately (Figure 1). This will enable planning for water recycle at the design stage itself. The benefits are many (Figure 2). We will now discuss some of the technologies for recycling of effluents. Membrane Bio-reactor Membrane bio-reactor (MBR) technology is one of the latest technologies in biological treatment. Submerged membranes are used in place of clarifiers to separate sludge from the waste water so as to produce high quality permeate. These MBRs can handle very high sludge concentrations in the aeration tank because of which the size of the aeration tank reduces four to five fold. As the membrane acts as a fine filter, it does not require any further treatment using sand filters, activated carbon filters, etc. MBRs are widely accepted and used in the recycle of domestic sewage also. Ultra filtration Ultra filtration (UF) is a very important technology in waste water treatment. It has many applications in waste water recycle, some of which are widely used, as listed below:

B2B Purchase

April 2015

• Pretreatment to reverse osmosis (RO) for producing good quality water • Colloidal silica removal • Caustic recovery • Colour removal • Bacteria and virus removal • Oil emulsion waste treatment • Treatment of whey in dairy industries • Electrocoat paint recovery • Concentration of textile sizing • Concentration of gelatine. UF is mainly used as a pretreatment to nano filtration (NF) and RO so as to reduce the silt density index (SDI), a parameter important to avoid NF/RO fouling.

Nanofiltration (NF) NF has a pore size much smaller than UF and hence can reject many colour-causing elements. NF can very effectively separate dyes and concentrate them too. This method of concentration and purification reduces the loss for dyes. Also, when dyes are removed from the concentrated salt solution, they can be reused in the process thereby reducing the pollution load and also saving water and salt. Reverse Osmosis (RO) RO is increasingly used in recycle of waste water for producing good quality water for reuse in the process. There is good improvement in membrane element design in terms of reducing Conventional Treatment Water Treatment Plant

Waste Minimisation

Technology fouling potential and increasing the life of the membranes. Low cost of membranes is making its application a viable option. RO is a membrane technology used for separation of salts from waste water so as to make it reusable in the process. RO is more useful to separate salts and organic compounds from effluents which are pretreated for removal of suspended/ colloidal matter and certain pollutants which are likely to foul the RO membrane systems. As some effluents contain high amounts of dissolved salts, RO is a suitable technology for separation of these salts and for producing permeate which can be used in the process.

Ion Exchange While membrane processes have become the technology of choice for recycling, ion exchange technology – in which the contaminated water is treated by passing it through a suitable column of ion exchange resin, is not to be ignored. Since the process of ion exchange is reversible the capital cost as well as disposal cost of ion exchange resin is low. In effluent recycle schemes, these resins can be used for proper pretreatment, organic reduction, colour reduction etc. Eletrodialysis (ED) This is an electro-membrane process in which the ions are transported through a membrane from one solution to another under the influence of an electrical potential. ED can be utilised to perform several general types of separations such as separation and concentration of salts, acids and bases from aqueous solutions or the separation and concentration of monovalent ions from multiple charged components or the separation of ionic compounds from uncharged molecules.

Water Treatment

proven technologies and many such installations are working in various industries. It is of utmost importance to involve water management specialists right from the planning stage of the project so that the most optimum solutions can be developed. Priority should always be given to source reduction and product recovery rather than end of pipe waste water treatment. Best technologies should be adopted for recovery and recycle of water from waste water. Final effluents which cannot be recycled should be treated and disposed of in an environmental friendly way. Apart from industrial waste water, nowadays, because of water scarcity, it is very important to recycle domestic sewage and the recycled water can be used for low end applications such as gardening, toilet flushing etc. Innovative and very compact sewage treatment systems are available and are working efficiently at various hotels, hospitals, and commercial and residential complexes. The domestic waste i.e. sewage and sullage, can be treated and recycled with the help of very innovative technologies such as membrane bio-reactors, fluidised media reactors, rotating bio- contactors, sequential batch reactors etc. In short, waste water recycling is the only holistic solution to the water scarcity and can meet the growing demand for good quality water even as water scarcity and pollution increases. n Authored by__ G. Sridhar, Associate Vice President – Southern Operations, Ion Exchange (India) Ltd.

Electrodialysis is used widely for production of potable water from sea or brackish water, production of ultra pure water etc. Following are some new applications in ED separation process: • Recovery of organic acids from salts • Deacidification of fruit juices • Heavy metal recovery • Acid recovery from etching baths, pickling liquors, etc. • Treatment of plating waste waters • Demineralisation of whey, soy sauce, sugar, fruit juice and organic acid.

Conclusion In conclusion it can be seen that detailed site analysis and piloting are essential to have a successful recycling programme. Detailed studies on the effluent, its behaviour on membranes of different polymeric construction and pore size, and chemistry enable design of a suitable system which meets the requirements of viability and sustainability in the long run. A combination of the above technologies is used in the industry for managing industrial waste water. These are the April 2015

Case Study

BOD of pulp and paper industry using Biosens The case study shows how Biosens can be a better means of measuring Biochemical Oxygen Demand biological oxygen demand of waste water using a sensor called as Biosens.

Biological Oxygen Demand (BOD) BOD is a measure of the DO consumed by micro-organisms during the oxidation of bio-degradable substances in waste waters. A high BOD would therefore imply a higher depletion in the DO content. If water with high BOD is discharged into common streams and rivers, the high depletion of DO will starve the rest of the aquatic life such as fish and insects. Waste water is therefore treated to bring down the BOD value to levels below those prescribed by pollution regulatory bodies.

aper manufacturing is a highly capital, energy and water intensive industry. These industries are disturbing the ecological balance of the environment by discharging a variety of wastewater. Depending upon the nature of raw material, the wastewater is generated per metric ton of paper produced. The paper making process requires large amount of water for the production processes, hence it is a water-intensive process. This is because, without the physical properties of water, it would not be possible for a consistent structure to be achieved when the constituents of paper are processed in sludge. Consumption of water depends upon the raw material used in industrial processes. The natural raw material used for the processes are wood, cellulose, vegetables, bagasses, rice husk, fibres and also waste-paper. This creates a high level of wastewater from processing.

The dark colour of the wastewater exhibits the toxic effects on the biota and inhibits the photosynthetic activity by reducing the sunlight. The paper mill wastewater characteristically contains colour, very high level of Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), due to presence of lignin and its derivatives from the raw cellulosic materials, chlorinated compounds, suspended solids (mainly fibres), fatty acids, tannins, resin acids, sulphur and sulphur compounds, etc. Most of these industries discharged their insufficiently treated waste into the rivers or streams, which makes serious problem to aquatic life and flora-fauna. Thus, it is necessary to analyse the physicochemical characteristics of the effluent and the influent of the effluent treatment plant of the paper mill. In this case study we are dealing with the measurement of

Significance of BOD as a water quality parameter, lies in the fact that it measures the impact on the environment (mass of DO consumed per litre of water mg/l) rather than a concentration of any harmful compounds.

Objectives of the study • Analyse number of waste water samples from various pulp & paper industries • Measure the BOD of all the samples using Biosens technology • Comparison of results for conventional BOD method and Biosens • Conclusions. Revolutionary method from FM: BioSens BioSens uses a measuring technique that revolutionises the way the BOD value of an effluent sample is determined. It deploys a special immobilised microbial membrane and a standard DO probe, together forming a Biosensor. This technique helps determine the BOD 72

value within 20 minutes of exposing the Biosensor to the effluent sample. This is in contrast to the 3 or 5 days required by the BOD3 and BOD5 methods respectively.

BioSens The BioSens system comprises of a computation unit (CU), a sensor unit (SU) and a support kit which includes essential lab-ware and tools. The CU and SU are interconnected by a set of cables. The SU provides a stable platform onto which a DO probe and a magnetic stirrer are mounted. The DO probe can be positioned suitably for different actions by means of a swinging arm and a clamping lever. The beaker containing the buffer-sample mixture is to be placed over the top surface of the stirrer. During measurement, the CU acquires the signal from the DO probe – which along with the immobilised membrane forms the Biosensor. The CU also drives the stirrer during specific phases of the measurement. The stirrer maintains the buffer-sample mixture homogenous during the measurement phase. A touch-screen interface on the front of the CU allows the user to perform the different functions including calibration, measurement, viewing reports and system configuration. Sample Location

The product has been engineered to minimise user errors by employing poke-yoke principles, preventing invalid actions, avoiding manual computations and textually prompting the user appropriately when required. BioSens also features backup of reports and printing of reports over dedicated USB ports. Future enhancements will support sending of reports via email, viewing of trends on client machines and ftp [file transfer protocol] of report file to external server.

PROCUREMENT GUIDELINES

Optimising performance in industrial wastewater treatment This article illustrates how an integrated wastewater-treatment system, with different types of equipment working hand-in-hand — specifically metering and peristaltic (hose) pumps, and polymer makedown systems — can be used in a straight-line treatment process. This delivers the cost-effective and efficient way to treat industrial wastewater, all while making it safe for disposal or reuse in any number of additional activities The challenge Most of the water used or produced in industrial applications contains some level of solid particles. It goes without saying that these particles should not be consumed, but particle-laden water also can’t be used, for example, in a boiler that provides steam to a turbine during power generation, lest the turbine become fouled and damaged. Recognising the presence of particulates in water and successfully

removing them, are two different things. Some of the particles—which can be anything from bacteria and plant material to dirt or minuscule pieces of crushed stone—are so small that their response to gravity is very low. In other words, they don’t fall through water at a consistent rate because their mass is so small and not impacted by gravity. This means that it may take many hours, days or even weeks for the particles to settle as little as a foot. This is an unacceptable, and unpredictable, settling rate for

a water or wastewater treatment system, so the particles need some help in settling or clumping. To speed along the settling or clumping process, the water treatment facility must turn to the introduction of a coagulant or flocculant that helps the tiny particles clump together in a mass that is called a “floc,” which is easier to remove. Two of the more popular types of coagulants/flocculants that are used in water and wastewater treatment are:

PROCUREMENT GUIDELINES Alum: Alum or hydrated potassium aluminium sulphate is being used since Roman times to aid in the purification of drinking and industrial-process water. Alum coaxes negatively charged colloidal particles to clump together so they will be able to be more easily removed from settling basins. Ferric chloride: Another name for Iron (III) chloride, ferric chloride undergoes hydrolysis when dissolved in water, which gives it the ability to sufficiently form suspended solid particles into flocs. While quite effective in creating flocs, the flocs that are formed by alum and ferric chloride are held together rather loosely, which means that they can break apart if agitated as they settle in the clarifier or settling basin. Eliminating this break-up potential requires the introduction of a polymer solution that helps form more efficient flocs. The polymer takes the neutralised solid particle clumps and binds them together more tightly.

The clumps that settle in the basin form a material that is called sludge. The use of alum by itself leads to the generation of a large amount of sludge; the introduction of polymer helps further coagulate the sludge. However, the sludge that is produced still needs to be removed and disposed of. Accumulated sludge can be collected and sent away to someplace like a centrifuge, or just piled up on the ground outside the water treatment facility, allowed to dry and then removed via front-end loader and dump truck. Removing the sludge from the water requires a pump that can run dry and wonâ&#x20AC;&#x2122;t be bothered by abrasive materials. In other words, a pump that has the capability to take whatever flows into itâ&#x20AC;&#x201D;no matter its makeup â&#x20AC;&#x201D; and deliver it out the discharge side in that same form.

The solution Industrial water or wastewater treatment, then, is a three-stage

Water Treatment

process that must work hand-in-hand: initial floc formation with alum and ferric chloride, clump strengthening with polymer, and removal and disposal of the sludge. Not all manufacturers of wastewater treatment equipment are able to offer full lines of pumping and polymer-blending technology for the required water treatment applications. However, Oakbrook Terrace, IL, USA headquartered PSG, a Dover company, does feature full lines of pumping and polymer-blending technology for industrial water or wastewater treatment applications. Specific watertreatment technology from PSG includes:

Neptune 7000 Series mechanical metering pumps Ideal for dosing alum and ferric chloride, these mechanically actuated pumps eliminate the use of contour plates on the liquid side of the diaphragm, resulting in a simple, straight-through valve and head design that allows improved flow characteristics. They

Abaque Peristaltic (Hose) Pumps play a pivotal role in sludge removal during a wastewatertreatment operation thanks to their ability to run dry and effectively handle abrasive, particleladen materials

As a supplier of all of the pumping and polymer makedown equipment needed for a water-treatment system, Neptune has the capability to create pre-wired and pre-piped skid-mounted arrangements

While most people’s first thought when considering water treatment is the municipal variety, there is also a huge market for industrial water and wastewater treatment. To help optimise their water-treatment operations, facility managers must identify and incorporate the proper pumping and polymer makedown systems, with Neptune Chemical Pump Co. a leading supplier of both

have been designed to handle clear liquids with viscosities ranging from water-like to 5,000 cPs, making them ideal for use in industrial water and wastewater treatment applications. The capacity of the 7000 Series pumps is manually adjustable via micrometer dial while the pump is running. This allows the pump to produce flow rates ranging from10 gph to 450 gph (38 L/ hr to 1,710 L/hr) at head pressures up to 150 psi (10 bar). The pump’s liquid ends are constructed of PVC, 316 stainless steel or Kynar. Wash down duty and explosion proof motors, as well as variable frequency drive options, are also available. The pumps are also selfpriming.

Fluid Dynamics dynaBLEND liquid polymer blending systems Fluid Dynamics, which is a division of Neptune, has designed the dynaBLEND with a non-mechanical mixing chamber that allows it to deliver an unequalled degree of reliability when activating all types of liquid polymer for use in water or wastewater treatment. The system’s injection check valve has been designed with easy disassembly and inspection in mind, eliminating a maintenance concern that troubles other systems. These features allow the dynaBLEND to apply ultra-high mixing energy at the point of initial polymer and water contact to prevent polymer gelling and agglomeration. The prolonged turbulence that the dynaBLEND process creates allows the polymer to complete the blending process gently and fully. Finally, after the polymer is initially activated, the dynaBLEND’s gentle mixing energy does not break the fragile long polymer chains that have been formed. Abaque Series Peristaltic (Hose) Pumps Featuring a design that ensures that “whatever goes into the pump comes out of the pump,” Abaque pumps can handle solid particles up to 18 mm (0.7”) and soft particles as large as 31 mm (1.2”), making them atop choice for sludge removal. They feature a seal-free design that eliminates leaks, which enables them to handle

the wastewater industry’s toughest pumping applications, from abrasive and aggressive fluids to shear-sensitive and viscous materials. The pumps, which can run in either forward or reverse, are self-priming, dry-running and offer suction-lift capabilities to 9 metres (25.5 feet), as well as the ability to run dry continuously without adversely affecting the pump’s performance. Ductile-iron and steel construction lets the pump produce discharge pressures as high as 16 bar (232 psi). The Abaque’s pump hoses are available in three materials of construction: natural rubber, EPDM and Buna N.

Conclusion Varieties of industries use untold millions of gallons of water and produce untold millions of gallons of wastewater every day. Properly handling and disposing (or reusing) this wastewater requires a number of stages that must work together seamlessly, from alum and ferric chloride introduction, to polymer injection, to sludge removal. Each stage requires a different type of technology, which can often have the wastewater-plant operator moving in many different directions to identify a solution. PSG offers a one-stop shop for industrial wastewater treatment, with a ready supply of metering pumps, polymer makedown systems and peristaltic pumps, all of which have been designed to work in hand-inhand to create the most efficient and cost-effective industrial wastewater treatment process. n Authored by__

INDUSTRY SPEAKS

Consistency: the major challenge in wastewater management sector I We envision Ikos GAIA to be a major player in the water sector in next 3 years. V. S. Pillai, CEO, Ikos GAIA

kos GAIA constitutes specialisation in EPC contracts, manufacturing and operation and maintenance of water and wastewater treatment plants. In an interaction with B2B Purchase, Mr Pillai discusses about the opportunities and challenges across wastewater management sector in India.

Water waste management is a rising concern in India. How does Ikos GAIA Infra address this national issue? The rate of pollution is rapidly rising across India. Fresh water resources are trickling away, as the illegal dumping of untreated wastewater into fresh water bodies continue unabated. There is a need for strict action from the government to address various concerns relating to wastewater management. Ikos GAIA, as a private entity, contributes towards creating awareness and offering innovative solutions for wastewater management. For instance, our Ozonator system directly treats wastewater and reduces contaminants to zero. In the process, Ozone is released into the atmosphere creating a healthier environment for us to live in. We are recommending this system and solution to our clients so that we all can contribute effectively to environment conservation.

What are the specialised solutions you provide? What make them special in Indian market? Our advanced Ozonator system is a unique solution we offer as our prime product in the market today. We differ in the process, whereby all systems are only used as disinfectant in place of chlorine disinfection. We offer our complete Ozonator system as primary treatment product for industrial effluent. This is where solutions offered by Ikos GAIA differ from the general applications. We have tested and proven the effectiveness

of our solutions by reducing the industrial effluent COD of 1,67,000 ppm to less than 1,000 ppm.

How does association with Lhotellier Ikos impact GAIA? Lhotellier Ikos France is our professional and financial support. Through them we will receive technology transfer in various sectors that we are venturing into. Where do you wish to place Ikos GAIA in the next 5 years? We envision Ikos GAIA to be a major player in the water sector in next 3 years. We are confident that by 2020, the company will have a turnover of more than Rs 1,000 crore and would be a leading brand in the wastewater management sector. What are the major challenges in wastewater management sector in India? Major challenges in the wastewater management sector are that of â&#x20AC;&#x2DC;consistencyâ&#x20AC;&#x2122;. This has two aspects to it. First is the consistency of system performance, that is, the solution provided must have a consistent output of treated water adhering to the PCB (Pollution Control Board) norms. This rarely happens and with the passage of time, the systems further falters in meeting the PCB norms in the absence of proper operations and maintenance. Second, the companies are not consistent with their commitment to their clients. They falter on making timely payment to vendors, delay progress of the work and neglect the welfare of employees. This tendency is rampant in the sector today. These companies eventually fail to deliver to their customers, and are often blacklisted. This impacts the overall wastewater management sector as well. n
