Risk Management Insight

Although Africa's growth prospects are bright, they differ not only country-by-country but also sector-by-sector. Many local and multinational consumer companies are already thriving in Africa and delivering handsome returns to their shareholders.

The face of Africa is changing and the growing industries in the continent prove it all. Thanks to structural changes in many African countries, productivity revolution is helping many companies to achieve greater economies of scale. Changing rigid policies in Africa and the fall of hostile regimes has led to a more energized market. Fueling the African economy, the oil and gas industry has boomed owing it to rising commodity prices. Following all these good happenings, industries in Africa are denitely growing

Entrepreneurs across Africa are taking up challenges by creating innovative healthcare solutions like telemedicine, e-prescriptions, m-health applications, which will help to free up congested health facilities. Did you know that Africa has become an international test base for innovative renewable energy solutions? For example, the solar energy revolution is in full swing and many businesses have chosen to be associated with climate-friendly energy solutions.

A technology-driven Africa is no surprise to anyone. Sectors like the nance and mobile telecommunications have witnessed revolution over the years.

TRAFFIC SAFETY MANDATORY CARRIAGE OF FIRE EXTIGUISHERS

In a bid to curtail vehicles from being burnt during accidents or mishaps on the road, the Ministry of Roads and Transport introduced Statutory Instrument 154/2010 which makes it mandatory for motorists to carry fire exnguishers in their motor vehicles. The instrument made it also mandatory for all motorists to carry the following accessories in the vehicles, jack, spare wheel, triangle portable red reflectors. This was a move meant to reduce vehicles from being completely gued by fire.

With the large influx of motor vehicles imported into the country, with most of them automac transmied work mostly on electrics. This has made them to be prone to fire in the case of accidents or electrical faults. Again the vehicles use highly pressurised fuel passed through to the engine through the fuel injecon system. This makes the vehicles vulnerable to fire should they be involved in accidents. One has to travel on some of the highways in the country to see the remains of some of this vehicles on the side of the roads. These could have been prevented from destrucon had the motorists carried with them fire exnguishers. Apart from the destrucon of the vehicles, roads and the areas affected the fire caused by these accidents has resulted in millions of dollars in damages.

The same Statutory Instrument made it

mandatory to carry a spare wheel, jack and reflecve triangle reflectors. This was seen as act to siphon money from motorists by government through the traffic cops. This instrument though not poplar with motorists has played a big role in the reducon of road accidents on the countries' roads. Red reflecve triangles at night warn other road users of the vehicle breakdown in front making them to approach the same with cauon. Some vehicles aer a break down could not be pulled of the road as one of their wheels may be damaged since they

would not have had a spare wheel. This has led to accidents with innocent people losing their lives simply because a motorist failed to move the vehicle to the side of the road. Most accidents occur at night when motorists fail to move their vehicles of the road and fail to put reflecve triangles to warn other road users. In line with the SADC Traffic guide lines which, call for all members states to conform to the SADC traffic regulaon Zimbabwe had to introduce this instrument to conform to the regional guide lines on traffic safety

Gas Sensing Technology Improves Safety

An underground mine is an inhospitable place in which to work. Gas poisoning and explosion is a major hazard, with many different types of gas commonly present in mines. Black damp, a mixture of carbon dioxide and nitrogen, is formed as the result of corrosion in enclosed spaces so removing oxygen from the atmosphere and potenally causing suffocaon. Fire damp mainly consists of methane, a highly flammable gas that explodes at concentraons between 5% and 15% or, if it does not explode, at 25% concentraon it causes asphyxiaon.

Methane ignion can trigger the much more dangerous coal dust explosions because the shock wave raises coal dust from the floor of the mine galleries to make an explosive mixture that is highly suscepble to spontaneous combuson. Snk damp, so called because of the roen egg smell of the hydrogen sulphide gas, can explode and is also very toxic. Carbon monoxide, toxic even at low concentraons, is another major hazard.

Gas sensors are the crical operang

component of all gas detecon instruments. They transform a gaseous concentraon, typically measured in ppm, into a change in electrical voltage or current that provides a reliable, stable and repeatable input for the detecon instrument. With so many different gaseous hazards potenally present, effecve gas detecon is crical in protecng life and equipment underground.

Apart from gas-related hazards, underground mining dangers include suffocaon, gas poisoning, roof collapse and gas explosions, while open cut hazards are principally mine wall failures and vehicle collisions. Most risks are greatly reduced in modern mines, and mulple fatality incidents are now rare in most parts of the developed world. However, according to the Bureau of Labour Stascs, mining remains the second most dangerous occupaon in America, with 30 deaths in a typical year due to mine accidents.

The Beneficial Impact of Modern Technology on Fatality Rates

Modern technology employed in mines throughout the developed world, has

dramacally improved safety. Improvements in mining methods such as automated longwall mining, effecve hazardous gas monitoring, gas drainage, beer electrical equipment and improved venlaon have reduced many of the risks of rock falls, explosions, and unhealthy air quality

In less developed and developing countries, many more miners connue to die annually, either directly as the result of accidents in mines, or indirectly as the result of illnesses contracted from working under poor condions.

The Challenges Facing Gas Sensor Manufacturers

In deep coalmines, extreme temperature changes, rapid humidity variaons and significant pressure changes are experienced as miners travel down from the surface. In both deep and open cast coal mines methane gas is an ever-present hazard. Specific regional issues are a further complicaon, for example, in South African mines, hydrogen cross-sensivity is a parcular concern.

Superficially, a gas sensor might appear to the untrained eye to be no more than a simple

Gas Sensing Technology Improves Safety

small cylinder, 20mm in diameter and 17mm high, with two or three electrodes. In fact, nothing could be further from the truth. Such an unremarkable looking component is the operang heart of all gas detecon equipment, which saves countless lives and prevents damage to property worth billions of dollars.

Oxygen Sensors

Gas sensors are in fact complex pieces of equipment: 4OXV, the new oxygen sensor, is constructed from more than 20 individual components, which are manufactured to exceedingly ght tolerances and assembled to create the finished product on an automated assembly and test line. As an example of the technology behind the design of gas sensors, consider the 4OXV oxygen sensor that is used in portable gas detectors in mines. Humidity changes are another significant cause of false alarms. 4OXV features an integrated moisture protecon membrane to prevent the ingress of humid air into the chamber. The implicaons in the mining environment are self-evident. Bump

tesng for personal gas detecon equipment, in which the instrument is exposed to its target gas to check for correct operaon, would normally take place on the surface. Descending in high speed lis to the working levels will result in rapid increases in temperature and humidity, potenally causing the instrument to false alarm, with a consequent loss of me and confidence while the issue is sorted out. Instruments fied with 4OXV do not suffer from such issues, improving efficiency and reducing down me.

Carbon Monoxide Sensors

“Speed is of the essence”. A truism applied to many different situaons, but a statement that is arguably crical in mining life safety applicaons, where delay can literally prove to be fatal. Carbon monoxide, a colourless, odourless, tasteless, and inially nonirritang gas is very difficult for people to detect. Exposure to 100 ppm or greater can be dangerous to human health, and as the symptoms of mild exposure include lightheadedness and confusion, while larger exposures can lead to death, the provision of

an effecve CO detector is an imperave for personnel who may encounter it during the course of their work. CO is commonly found in mines, so a fast and effecve CO detector is an essenal piece of equipment.

The Future

Without doubt, today's sophiscated gas detecon technology has saved many lives in what is sll one of the world's most dangerous industries. Gas detecon instrument manufacturers typically rely on gas sensors from specialist manufacturers. Typically based on electrochemical technology, the characteriscs of the gas sensor itself determine, to a great extent, the instrument's performance and reliability in use. To offer their users reduced lifeme cost of ownership, enhanced performance and features that improve the funconality, reliability and effecveness of personal and fixed gas detecon, OEMs require the gas sensor manufacturers to innovate sensors that have beer stability, greater resistance to cross-contaminaon, longer life and faster response.

The leap to Level 9 –'Zero-Harm' and maximum productivity with integrated CAS solutions

Proximity detecon and collision awareness is a crucial focus area in the drive to reduce fatalies in mining, contribung to the levels of protecon against the risks associated with vehicle interacons on a mine. Collision avoidance ranked top of 13 different technologies idenfied by 47% of mines globally and 57% of mines in Africa as expecng to see significant investment in the coming two years, based on the 2022 GlobalData survey.

South Africa is leading the way in the drive to implement the highest levels of collision awareness systems (CAS) to the Earth Moving Equipment Safety Round Table (EMESRT)

Vehicle Interacon Defensive Controls Model Level 9 (intervenon controls), where electronic systems automacally slow down the machine and apply a controlled stop if a dangerous interacon is detected when the operator has failed to take evasive acon to

the prior Level 7 (Operator Awareness) alarm and Level 8 (Advisory Controls) alerts. Level 9 Collision Awareness (CAS) vehicle intervenon for both underground and surface mining became mandatory in South Africa in December 2022. Companies that are not compliant, must submit a plan on becoming compliant. There is a strong need for future-proof soluons that can be rapidly implemented.”

The leap to Level 9 – 'Zero-Harm' and maximum productivity with integrated CAS solutions

The Level 9 standard is a major leap from Level 8, which required systems to deliver an advisory instrucon to operators. Now, electronic systems must automacally take mechanical control of the vehicle and slow down and apply the brakes at any mine where there is a significant risk of such collisions.

Implemenng reliable integrated systems that can comply with Level 9 requires long term commitment and solid investment in sophiscated CAS systems that provide high integrity object detecon, operator warning and automac intervenon, when necessary, in order to prevent an accident. It must be far more than a box cking exercise, with integrated technology implemented in a holisc way that avoids the challenges of operator alarm fague, sensing technology inaccuracies, unnecessary alarms during normal operaons and reduced system availability – all of which can impact producon.

The data collected from mulple sensors

related to the potenal incidents drives enormous value for safety and producvity, especially when Arficial Intelligence (AI) and Machine Learning (MI) can be applied. For example, traffic flows can be managed and opmised to maximise producon.

At Probe IMT, we have been working with carefully selected industry-leading soluons to help our clients ensure that they can meet the requirements of Level 9 intervenon controls. Evolving CAS soluons set new standards for workplace safety and facilitate 'zero-harm' objecves and producvity objecves through effecve, reliable and intuive operaon. CAS Level 9 enables the safety of all personal in mines, and safer mines become more producve mines in the long run.

New Wabtec CAS Generaon 3 Soluon is a gamechanger for Level 9 compliance

The Wabtec Collision Awareness Soluons Suite is a sophiscated and adaptable collision awareness and reporng system

developed specifically for the mining industry with the aim of making mining operaons safer, while helping to ensure opmal performance at a lower sustainable cost. Using advanced technology field hardware and communicaons soware, with real-me system health monitoring and event reporng, the Wabtec Digital Mine's safety technology provides industry-proven reducon in vehicle interacon risk. With the right reporng and analycs tools to monitor and manage operator behaviour, safety culture and compliance can rapidly be improved.

Wabtec has announced the launch of its nextgeneraon Collision Awareness (CAS) Generaon 3 soluon, represenng significant advances in sensing accuracy, user experience, and EMESRT Level 9 vehicle controls. Implemented by mining soluons company Probe IMT across Southern Africa, this proven technology sets the standards for mining safety and is an ideal soluon for mines striving to achieve their zero-harm goals. Fleet-wide implementaon is

The leap to Level 9 – 'Zero-Harm' and maximum productivity with integrated CAS solutions

underway at key sites.“CAS Generaon 3 has been developed to provide game changing performance and user experience," says Gert Roselt, CEO of Probe IMT. “This breakthrough from Wabtec is the result of mulple years of field and producon tesng, leveraging the invaluable insights of Wabtec customers and the industry. CAS Generaon 3 offers unique funconality and is the only system to include real-me health monitoring. Powerful intelligence delivers up to fiy mes beer alarm performance, compared to the market. Wabtec's intensive producon tesng has ensured a lower nuisance alarms rate, meaning there is less impact on producvity.”

The Wabtec CAS Generaon 3 soluon is designed to reduce crical vehicle interacon risk through features including smart rules and intelligence, remote monitoring, troubleshoong, 360-degree situaonal awareness, ultra-high accuracy sensing, producvity monitoring, machine data acquision, crical vehicle interacon threat advisories, and detailed reporng and analycs. The soluon offers a user-friendly, intuive interface and is fully configurable with adaptable sengs to fit site-specific requirements. CAS extensions can include integraon with Driver Fague Monitoring Systems, Fleet Management / Dispatch Systems, machine vision and Asset

Performance Management for mobile equipment.

The surface offering can be deployed with a variety of proximity detecon methods including GNSS, radio frequency (RF), VLF magnec and cameras to provide one of the most effecve high integrity systems on the market. The vehicle display unit includes touchscreen HMI, with graphics display of remote objects showing ID, range, speed and heading with configurable audible, voice and visual alarms. Robust wide-view cameras eliminate blind spots with auto switching on direcon of travel and to zones of object detecon. Further features include equipment health monitoring, maintenance tracking, blending, and producon reporng. A strong differenator is the high integrity proximity detecon using high accuracy GNSS augmented with me of flight (ToF) RF combined with real-me monitoring and connecvity provides 360˚ protecon for vehicles, equipment, and personnel. Strategically placed proximity units afford operators unparalleled situaonal awareness—contribung to improved safety levels on-site. Back-to-base reporng provides interacon reports, journey replay, hot-spong, geofenced exclusion zones and alarm events, safety adherence reports and

system health monitoring.

Roselt explains that recent rapid advances in technology, such as satellite posioning, LiDAR, intelligent vision systems and faguedetecng soluons, have all had a major impact on collision avoidance systems and the level of soware that is available to mining companies. “With proper system integraon and a whole-of-mine safety approach, mines can reap huge benefits from implemenng high-performing soluons.”

While South Africa has over 30 CAS suppliers, varying from established providers to small new entrants, few can offer the proven track record of mulnaonal players, says Roselt. “Mines should carefully select implementaon partners and technology to ensure a smooth transion to Level 9. Wabtec soluons help our clients comply with Level 9 regulaons, but also avoid the pialls of sensing technology inaccuracies, unnecessary alarms during normal operaons and reduced system availability that can impact producon. Fieen years of operaons with no fatalies or unreported events prove Wabtec's commitment to safety and reliability. We're proud to be implemenng these soluons in a rapidly evolving arena.”

Benets of Clamp-on ow metering in Mining and Metallurgical Operations

Clamp-on flow measurement using the ultrasonic transit me technique has matured and is now a preferable technology for control and monitoring in many metallurgical and mining applicaons. In general, if any two of the following are present then Ultrasonic Clamp On (USCO) should be considered or even preferred.

We at Flexim, as the leader in this field has seen an increase in requests parcularly in the following areas:

Water monitoring and stewardship

Mines and minerals use water in various ways, from high pressure hydro power lines

in underground mines to drive drilling equipment, to a solvent in hydrometallurgical operaons to dust suppression, the common denominator is a requirement to responsibly and efficiently use and account for the water to do the least harm to the environment and nearby communies. Flexim's rugged portable meters are ideal for audits and reporng while the fixed meters are in many cases beer suited than the tradional mag meter

SO Abatement 2

Sulphuric acid producon as a method to reduce SO emissions is increasingly 2

becoming a preferred route to reduce this pollutant. The benefits are no addional waste streams, a saleable product and, depending on the technology, low addional water and other input requirements. A unique feature of metallurgical SO fed 2 Sulphuric acid plants is the fluctuaon of the feed SO concentraons and the resulng 2 affect it has on the stable operaon of the plant. Flexim meters are an ideal soluon as they can be retrofied with no shutdown (no fines or risk to equipment during start up) give both flow and concentraon measurement and work on both metal and GRP pipes. “We have recently installed meters on plants in Zambia, the DRC, South

Benets of Clamp-on ow metering in Mining and Metallurgical Operations

Africa and Namibia”, says Mark Middelhoven the Africa Sales Manager, and all our customers have seen improvement in their plant performance.

Solvent Extracon

SX circuits both water and hydrocarbon mediums and USCO is a good measurement technique as it can measure both phases. Typically these are installed on the organic side, recently Flexim has been involved in a project to provide metering on SX cells as part of an automaon project. Previously this had been done by manually adjusng the valves, but as the trend to more automaon

and reduced personnel connues the need to automaon and the benefits of beer control and efficiency the scope and usefulness of USCO is a key enabler

Energy efficiency

As the world moves towards a Net Zero future mining is key both in reducing its carbon emissions but also providing the raw materials for baeries, electrical infrastructure and catalysts for hydrogen producon. It is not surprise then the mines are invesng in improving their energy efficiency. Flexim again can help whether it is measuring steam in the processing plants or

compressed air, addional metering points can be safely added hassle free.

One aspect holding back the adopon of Clamp-on is previous bad experience, either through cheap portables or incorrect specificaon. Since the meters are able to be installed outside the pipe, with no interrupon, it is easy to de-risk the decision through a trial or demonstraon. At Flexim we are happy to stand behind our product and a try before you buy approach is usually enough to convince scepcal stakeholders. The technology has matured and should be the first choice of technology in many instances.

TAILINGS RECOVERY SYSTEM (TRS)

The Tailings Recovery System (TRS) is a technology developed specifically for recovering tailings from mine tailings pond deposits, to facilitate tailings pond reclaim operaons and management of tailings storage facilies within an operang mine site. TRS can also be ulized for the remediaon of legacy tailings ponds, and reprocessing mine tailings to extract valuable minerals.

TRS has been developed by Technika Engineering Ltd., a company based in Calgary, AB, Canada.

TRS effecvely addresses the operang limitaons of the technologies tradionally ulized for mine tailings reclaim operaons, including CSD dredges and submersible pumps. The limitaons of these technologies include inconsistent tailings supply density and the need for frequent relocaon on the pond. Dredging causes high turbidity of the pond surface water, which is oen reclaimed

for the process requirements. Dredges and pumps are suscepble to plugging by various debris that is commonly found in tailings deposits.

Dredging is a crewed operaon requiring people to be deployed on the pond, and may also be affected by seasonal weather condions.

TRS technology is an unmanned, remotely controlled operaon. Its control can be effecvely integrated into the overall control system of the tailings treatment facilies, which enables the supply of tailings at a density and flow rate that is opmum for the performance of the tailings treatment processes.

TRS can operate from a single locaon for an extended period of me without a need to relocate.

TRS operaon is based on a balance of parameters that include its geometry, tailings rheology and recovery rate. The operaon of the technology is based on the principles of the hydraulic pressure balance within the tailings pond deposits and the TRS caisson structure. The operang interface between TRS and tailings deposits effecvely mobilizes the tailings within the pond deposits creang the tailings draw zone. The mobilized tailings are brought to the surface within the TRS caisson envelope.

The tailings of the required density are

accessible from the surface for collecng and transport to the shore-based facilies.

The TRS caisson typically comprises two telescoping shells that allow easy adjustment of the pumping depth. The telescoping shells can be elevated to facilitate the system's launching, deployment, and relocaon.

The TRS assembly is of a modular design. The modules, which are designed to fit shipping envelopes, facilitate transportaon and minimize me to assemble the system onsite. This also enables easy relocaons between different tailings ponds or the mine sites.

An inial set of TRS units was developed by the Technika Engineering team and successfully deployed in large-scale tailings recovery operaons in the Canadian oil sands industry

The Company is now looking for opportunies to expand into other mining areas where the TRS technology can provide a valuable contribuon to mine tailings reclaim and tailings management operaons.

The TRS technology is patented and proprietary to Technika Engineering Ltd. For addional informaon, please visit hps://wwwtechnikaeng.com/technology/tailings-recoverysystem-trs.html

GEOGROUP: SONIC DRILLING SERVICE PROVIDER

Over the years, sonic drilling has connued to evolve, with improvements in vibraon frequency, power output, and drill bit design. Today, sonic drilling is a widely used technique for a range of drilling applicaons, from mineral exploraon and geotechnical surveys to environmental monitoring and geothermal energy producon Its advantages over convenonal drilling methods include faster drilling rates, reduced waste material, and beercorerecoveryrates.

Sonic drilling is parcularly effecve in soer materials such as clay and sand, which can be difficult to drill using tradional rotary core drilling methods. The sonic drill head allows the soil sample to enter the single tube core barrel by liquefying the ground on the sidewall ofthesampleenteringthecorebarrel,without disturbing the sample, thus providing very good core recoveries in the soer more friable ground in which is tradionally more difficult toprovidegoodcoresamples.

To date, the GeoGroup is a preferred supplier of sonic drilling services to the African connent.Outofthe3Sonicrigsintheirfleet,2 of these rigs are equipped with dual head masts able to switch between sonic and rotary core drilling. This eliminates the need to have mulple rigs on site as the mast head can quickly transion between Sonic and Rotary core.

The GeoGroup recently introduced the Secon Compact Sonic Crawler 190kN to their porolio which can be operated remotely by two drill operators with wireless controllers. Using a wireless control system to operate a drill has several advantages over tradional wired controls. Here are some reasons why wirelesscontrolmaybepreferred:

1

Mobility and flexibility:With a wireless control system, the operator can move around the drilling site more freely, without being tetheredtoacontrolpanelorconsole.Thiscan be parcularly useful in drilling projects where the operator needs to move around the rig to access different drilling locaons or perform othertasks.

2

Increased safety: By eliminang the need for cables and wires, wireless control systems can reduce the risk of accidents and injuries caused by tripping over cablesorgengtangledinwires.Thiscan be especially important in drilling projectswheresafetyisatoppriority.

3 .

Improved efficiency: With a wireless control system, the operator can control

the drill from a distance, which can be more efficient and faster than manually adjusng controls at the drill site. Addionally, some wireless control systems offer advanced features such as automaon and remote monitoring, which can further improve efficiency and producvity

and avoid falling objects says expert

Falling objects can deliver a hey blow to the head, resulng in injury or even death warns a safety authority

This is why WorkSafe is cracking down on companies that fail to control the risk of falling objects, with a round of almost 1000 inspecons throughout the next three weeks. Top targets will be construcon companies operang in the industrial, residenal and commercial sectors.

According to WorkSafe stascs, more than 860 construcon workers have been injured since 2010 by falling objects. Injuries are commonly caused by falling building materials such as bricks, les, concrete and mber.

WorkSafe says simple steps to avoid falling objects include securing loose building materials and tools at building sites, and could make the difference between life and death.

“Each year WorkSafe invesgates serious injuries and countless near-misses involving

falling objects at construcon sites,” WorkSafe health and safety execuve director Marnie Williams says.

“We know that even a small tool or a bolt falling from a building site can cause lifethreatening injuries. That's why every builder must assess their site throughout the day and idenfy materials or objects that could fall in or outside of the site boundaries.” Materials placed close to the edge of an incomplete upper level or le unsecured pose a very high risk.

“Materials that are blown from structures by wind or tools and equipment knocked or dropped from ledges not only pose a risk to workers but the general public in the streets below,” Williams says.

“Any object, no maer how small, can be deadly if it falls from a height so builders need to constantly assess the work being undertaken to ensure these kinds of materials are secured.”

SewTreat To Provide Eco-Friendly Innovations In Onsite Wastewater Treatment

By making use of the latest advancements in sustainable wastewater treatment combined with the creaon of their own bacterial strains developed in-house, SewTreat are able to answer the needs of industrial, construcon and mining operaons with efficient, affordable and eco-friendly waste water treatment soluons.

SewTreat is a proudly South African company offering specialized, modular biological waste water treatment plant designs tailor-made for the South African and African market. Their approach is based on return acvated sludge technology incorporang submersed aeraon media. This enhanced bacterial acon ensures a highly effecve treatment process boasng a very low carbon footprint, minimal capital input and low maintenance requirements.

Understanding the Needs of the Market

“Our approach is to treat nature with nature through sustainable engineering soluons

that are evident in our superior proprietary biological technology. The modular design of our treatment plants makes us a leader in providing waste water treatment soluons for the African connent,” says SewTreat Managing Director and spokesman, Theunis Coetzer.

Although the company is newly formed, SewTreat has already become an established name synonymous with internaonal experse in providing quality products and services to all sectors throughout SubSaharan Africa and especially in the SADC region. The SewTreat team consists of process and civil and process engineers, microbiologists, project planners and a network of distributors with over 35 years of experience in the field.

“We have developed our products and services to embrace our customers' operang environments and the ongoing demand for environmental, social and financial

sustainable soluons,” Coetzer explains. “The team at SewTreat has extensive experse throughout various disciplines and so we are able to offer turnkey services which incorporate consultaon, design, manufacturing, installaon, construcon and operaonal support to our clients that meet all legal and industry related compliance.”

Product Offering

SewTreat offers several modular waste water treatment plants tailored to meet the needs of industrial sized, mining and construcon operaons.

1. Plasc HDPE Tank Waste water treatment plant

The plasc range makes use of plasc 'Jo-Jo' type tanks that are connected in series or parallel depending on site space requirements or layout. The plant is wholly constructed and cold commissioned before

delivery to client premises. The installaon me required onsite is minimal – a 50kl per day plant can be assembled on site in less than five days. A guarantee of up to 20 years is offered on the tanks depending on the type of tanks used in the plant. “We developed this range based on a need we saw in the market for a more cost effecve soluon for sewage treatment.,” Coetzer explains, although he notes that while the plasc plants are cost effecve in term if capital expenditure, the do carry very high shipping costs and so he does not recommend them for installaons outside of South Africa.

2. Containerized Waste water treatment plant

The containerized plant is well suited to rugged African condions. The concept is based on a 'plug and play' design, Coetzer explains, saying that they are designed for ease of transport, security and modularity, taking into consideraon that the plant may be moved to various locaons. “The complete WWTP is built into ISO High Cube Containers. The plants are can be easily moved from site to site, can be easily expanded and have a once off cost to the client as they can be moved from site to site as needed,” says Coetzer

“Our recent upgrade of our design makes this a very compeve opon for onsite waste water treatment. The plant is wholly constructed and tested at our 5000m² underroof facilies which ensures that all boxes are cked in terms of quality control procedures. The containerized plant offers a life span of 15 to 20 years which is excellent for a plug

and play soluon,” says Coetzer explaining that installaon literally requires only connecng of pipes to the waste water treatment plant.

3. Civil Constructed Waste water treatment plant

Their civil constructed plants are designed and constructed mostly for large flow industrial and housing development applicaons. The plants are aesthecally pleasing as they are constructed underground and can be covered with vegetaon and are enrely civil designed and constructed to exact civil engineering requirements. These plants boast several advantages for clients including the fact that the civil construcon can be subcontracted to local contractors to reduce construcon costs.

Coetzer explains that provision can also be made for easy plant expansion through simple modular and common wall construcon and that if the plant is gravityfed, the system can operate without electricity for up to 48 hours. This makes the product an effecve alternave for remote operaons, for countries with unreliable power supply, or where no municipal connecon is available.

A Greener Approach

Biological waste water treatment is an accepted pracce used worldwide. The process involves confining naturally occurring bacteria at a very high concentraon in the treatment process, whether it is plasc type, containerized type of civil constructed type. From here this bacteria, together with some

protozoa and other microbes (collecvely referred to as acvated sludge) are treated in an anaerobic and an aerobic process. They are then returned to the anaerobic phase to eliminate sludge accumulaon and waste generaon.

“In a nutshell, the bacteria digest all impuries and the wastewater is then cleansed. The treated wastewater or effluent can then be discharged to receiving waters –normally a river or the sea – or alternavely used for irrigaon, flushing of toilets or general non-potable uses,” explains Coetzer. “SewTreat has developed a highly effecve mulple strain bacteria range that gets added to our plants, this specifically bred bacteria feed on the complex substances in the wastewater, converng them into simpler substances, improving final effluent on a reduced footprint.”

He notes that globally, the composion of effluents discharged to receiving waters is regulated by the naonal environment agencies. The legislaon is concerned with the prevenon of polluon, and therefore sets concentraon limits on dissolved organic carbon (as BOD or COD), nitrogen and phosphates and other compounds which cause eutrophicaon in receiving waters. It also aempts to limit the discharge of known toxic chemicals by seng allowable concentraon limits in the effluent. “If we consider that 100% of the effluent can be recycled, if done properly, there is no doubt that through this we are providing large bank of water, which previously may not have been considered as 'safe' for the environment or community”
