Apaper published by Massachusetts Institute of Technology’s Schwarzman College of Computing states that ‘the cloud’ has a greater carbon footprint than the airline industry. The major component of the cloud is, of course, data centres, and the majority of a typical data centre’s footprint comes from its energy use. However, only a tiny percentage of that energy – the report suggests between six and 12 per cent – is consumed by active computational processes. The rest is drawn by multiple layers of redundancy protection, which is often vital but rarely called into full service, and the cooling systems needed to deal with the immense amount of heat generated by the technology in operation.

The demand for processing power is never going to reduce; indeed, its growth is exponential, fuelled by the surging demand for smart devices and, of course, generative AI (apparently, a ChatGPT query uses six times the energy of a Google search). So, it is essential that ways to reduce the energy requirements of data centres are found and implemented quickly.

On page 20 of this issue, we examine the role energy-efficient pumps can play in tackling this challenge as part of a revolutionary cooling method.

Elsewhere in this issue, we look at the parameters that should be considered when sizing a pressure-boosting system; we examine some pump alternatives for severe-duty applications; and we discover how ultrasonic flow measurement can revolutionise sewage systems.

We also cover the latest industry news, reveal a range of new products for pumping applications and share details of a selection of projects demonstrating how often experienced challenges are overcome. I hope you enjoy the issue.

CHEMUK records a 17% increase in visitors

CHEMUK 2024 OPENED ITS DOORS ON 15 and 16 May at the NEC in Birmingham to what the organisers say is a record attendance of 4,641 visitors over the two days, representing an increase of 17% from the 2023 edition. The total twoday attendance combining visitors and exhibitors was 6,677.

CHEMUK show founder Ian Stone summed up the positive response to this year’s event: “Standing in the hall midmorning on the first day was electric. There was so much volume and energy in the hall, with our biggest concentrated audience ever from literally every corner of the sector.

“I think the seniority of attending technical, scientific, supply chain, and business visitors rocketed to a whole new level this year, with one visitor badge after the next from the biggest names across the sector.”

Visitors to the event were invited to an exclusive pre-recorded address by Minister Mak, Minister for Industry and Economic Security at the Department for Business and Trade, and Minister for the Investment Security Unit at the Cabinet Office.

The address was supported by a comprehensive UK Government footprint at the show, with several government departments exhibiting this year, including the Department for Business and Trade,

the Department for Environment, Food and Rural Affairs, the Health and Safety Executive, the Home Office, and the Department for Energy Security and NetZero.

CHEMUK redefined itself this year with the introduction of several subbrands, including the Chemical & Process Engineering Show, the Chemicals Supply Show, the Chemicals Management Show, and the Chemical Laboratory Show.

The organising team was delighted to see an increase in both the number and quality of visitors, which they largely attribute to the introduction of these more focused show

zones.

Ian added: “The introduction of individual sub-branded shows underneath the ‘single destination’ CHEMUK24 brand has been a great success and allowed attendee groups to lock onto their primary focus area, whether as a process engineer, analytical chemist, hazardous transportation manager, and so on, whilst still benefiting from the serendipitous opportunities, intelligence, and connections drawn from the other branded show streams.”

The 2025 edition of CHEMUK will take place at the NEC, Birmingham, on 21 and 22 May.

WATT DRIVE ANTRIEBSTECHNIK RECEIVES NEW COMPANY NAME

WATT DRIVE ANTRIEBSTECHNIK, AN Austrian manufacturer of geared motors and drive solutions for the industrial sector, which has been part of the WEG Group since 2011, has been renamed as WEG Gear Systems.

The Brazilian group has greatly expanded its product range in recent years to offer integrated solutions for the entire drive train. This has also given Watt Drive a specialist role within the group. Under the new name, the WEG Gear Systems site in Austria will be upgraded to a competence centre for gear technology and will be responsible for the group’s global business for gears and geared motors with immediate effect.

“The new company name expresses the affiliation to our parent company,

WEG, even more clearly and further increases awareness of the WEG brand in Austria as well,” explained Klaus Sirrenberg, Managing Director at WEG Gear Systems. “In this way, we can make even better use of our parent company’s global presence and leading market position to further expand our position as a provider of drive solutions and specialist in gear technology worldwide.”

The company was founded in 1972 as an engineering office for drive technology by engineer Hans Wustinger. This was followed by expansion with its own assembly plant and production machines for small series production. In 1990, the company was given the name Watt Drive Antriebstechnik GmbH and the location in Markt Piesting in southern Lower Austria, including its own production department for gear components and the assembly plant. This was followed by the establishment of branches in Germany and Southeast Asia. The WEG group took over in 2011 and the gradual integration into the group began with major investments in the conversion and renovation of production halls and warehouses.

BUBBLE-DETECTING SENSORS PROTECT PUMPS FROM UNWANTED DOWNTIME

HELPING TO PROTECT PUMPS FROM running dry and detecting even the tiniest bubbles in flow control applications is a good example of how system engineers can prevent unwanted and expensive downtime due to pump malfunction caused by unwanted gas inclusions.

The PAD20 sensor from Baumer, a finalist in two categories at the recent Pump Industry Awards, is a ‘smart’ sensor that not only protects pumps from running dry but also ensures maximum system performance and optimum resource use.

The PAD20 sensors are an effective, robust solution for detecting air and gas bubbles in any liquid or viscous media, such as fruit preparations and cooling agents (DC>1.5), particularly in harsh ambient conditions. Switching outputs are individually adjustable with IO-Link for definition of switching range, or two-stage alarms (early warning), and

they provide optional multi-colour process visualisation through 360º of switching state.

The sensor can reliably and quickly measure air in all types of liquids, regardless of whether they are pasty or viscous.

The PAD20, initially developed for a German dairy company, proved its worth by solving their decades-old problem of containers not being fully emptied. This sensor is not just about protecting pumps; its reliable detection of gas bubbles also optimises the energy efficiency of cooling and heating systems in various industrial

HIGH-TECH CONTAINMENT SHROUD FOR MAG-DRIVE PUMPS

KSB GROUP’S NEW 3D-PRINTED CONTAINMENT SHROUD

for mag-drive pumps in the Magnochem type series, named MagnoProtect, offers the same safety as a double-walled containment shroud – without the latter’s disadvantages of heating up strongly and having high eddy current losses.

While providing comparable safety, the overall efficiencies of the new mag-drive designs exceed those of canned motor pumps. Designed with a structure of channels, the new containment shroud offers a second, redundant, static safety barrier preventing leakage of the fluid handled.

A pressure transmitter monitors the vacuum generated, which is present during normal operation in the channels of the containment shroud. If the monitored pressure rises to atmospheric pressure, the outer containment shell is leaking. If the pressure rises above the ambient pressure, the inner containment shell is damaged. The containment shroud design is characterised by high mechanical strength and good wear properties. It has been optimised to minimise heat losses and eddy currents.

Converting a standardised chemical pump with a mechanical seal to a magnetic drive is easier and more cost-efficient than retrofitting it with a canned motor. The geometry and dimensions of the new containment shroud are integrated

SENSITIVE PUMPING OF HIGHLY VISCOUS MEDIA

THE NEW TR SERIES WOBBLE PLATE PUMPS FROM Lutz Pumpen enable the sensitive pumping of up to 30,000 litres of highly viscous liquids per hour.

A spherical pump housing accommodates a wobble plate that sits at an angle on a shaft. The rotation of the shaft causes the plate to perform a characteristic wobbling movement. This continuously changes the volume of two chambers on both sides of the shaft which creates alternating positive and negative pressure, and draws liquids into the pump and expels them through an outlet opening. An efficient principle that has proven itself with highly viscous liquids such as oils, lubricants, varnish, sealants and silicones.

The new industrial pumps can handle thick or viscous liquids and media containing solids with a viscosity of up to 1,000,000 millipascal seconds and a temperature of up to 205 °C. They are suitable for applications in a range of industries, including paints and coatings, sealants and adhesives, pharmaceuticals, cosmetics, oil and the food processing. www.lutz-jesco.com/en

into the modular system of Magnochem, allowing metallic or ceramic containment shrouds to be replaced easily. This enables operators to upgrade older pump sets that are still in service without difficulty.

TEN YEARS OF UNINTERRUPTED SERVICE

AT THREE SINGLETON BIRCH biogas plants in Northern Lincolnshire, four rotary lobe pumps, made by Borger, have completed ten years of uninterrupted service.

Operating at the main Singleton Birch 2MW site in Barnetby, which has three 2800m 3 digesters, two Borger pumps are an important part of a process that, at full power, utilises imported maize (70 ton), sugar beet (40 ton) and chicken litter (10 ton) for its feedstock.

Established in 2014, and then expanded two years later with a third digester, additional silage clamps and two more CHP engines, the principal Singleton Birch facility contributes 86% of the power required for the 2.3 hectares Singleton Birch site, which for over two centuries, has produced high quality lime products.

At two smaller (500kW) AD plants

at Elsham, near Scunthorpe, and Willoughton, near Lincoln, a Borger pump operates at each, transferring liquid feed overflow into a drying system.

“Over the years, we’ve developed a very good partnership with Borger,” said Danny Mason, Renewable Energy Manager at Birch Energy.

“The equipment is very reliable and easy to maintain, and when we need spares or just a bit of advice, Borger’s Richard Marcinkowski is just a phone call away, always ready to help us out. This gives us peace of mind that our AD operation won’t be affected by any downtime.”

He added: “The pump application here means that wear and tear is inevitable, but Borger always keep right on top of the servicing schedule and the flow of spare parts, so that we are never without.”

In 2018, the HVAC system at a popular Caribbean holiday resort suffered a series of failures and leaks, resulting in frequent downtime. An initial review determined that the existing pumps were the cause and had to be replaced. The review also noted that the pumps were oversized, which affected system efficiency. With the resort occupancy rates near 95% for most of the year, HVAC performance and reliability are crucial, so managers decided to go ahead with an upgrade.

Because local rates for electricity averaged $0.28 per kilowatt-hour (kWh) at the time, the project represented an opportunity for the resort to reduce its energy costs as well as its carbon footprint. After assessing the HVAC system, Armstrong recommended Design Envelope Vertical In-Line pumps to replace the existing primary and secondary pumps.

The team at the facility was impressed by the space savings created by the Vertical In-Line design and noted that subscribing to the Pump Manager service, which provides alerts, alarms and performance analysis data, made it easier to track equipment status

and performance and support optimal efficiency and occupant comfort.

“Since our hotel is located on an island, we need a system that’s easy to maintain. The performance reports and messages provided by the Pump Manager are very helpful. Plus, the team at Armstrong is always available if we have any questions,” explained the resort’s manager.

The upgrade project provided a simple payback of less than two years and saves over $170,000 annually. The management team at the hotel is very focused on reducing its carbon footprint, so the annual energy savings of 558,000 kWh are an important measure of success.

WHEN AN EIGHT-STOREY BUILDING

in Trafford Park recently ran out of water to the top two floors due to ever-decreasing mains pressure, it caused large-scale operational issues on site. They quickly needed to find a permanent solution to boost the water supply to the property.

Working with its customer Equans, which undertook several enabling works, Pressboost was able to locate a room on site that it could use for tanks and a booster set and quickly sourced the equipment needed.

Then, over the course of two days, the incoming mains to feed two new storage tanks was modified and a Lowara GHV20 Hydrovar X Booster Set was installed to boost the supply to the property.

The entire property now has boosted supply and a future-proofed solution for its water distribution.

The two tanks allow for future maintenance without disruption. The new booster set benefits from highly efficient IE5 rated motors, a flow through expansion vessel and valve, and Hydrovar X inverters.

TOUGH PUMPS, POWERFUL PERFORMANCE

In everything we do, we never lose sight of what it‘s all about for you: economical work and easy handling.

Whether chemical substances, oils or media for the food industry, it is important to fill or empty quickly and precisely. Due to the reversible conveying direction, both processes can be carried out with just one pump.

As a result of their compact yet powerful construction, Vogelsang rotary lobe pumps are among the most frequently ordered pumps in many UK industries. They transport highly viscous or aggressive media of all kinds and even pump liquids with rough solids without blocking.

PUMPING SOLIDS WITHOUT SCREENING

CLIMATIC CHANGES FORCE US TO save water. Given that the pollution load has remained the same, the solids content in wastewater has increased, which has been a technical challenge for wastewater treatment plants. Until now, upstream pumping stations have had to implement costly measures to ensure reliable operation. KSB has responded to this problem with a new technical development that eliminates a previously essential step in pumping stations.

Many years of close partnerships with customers have provided KSB with detailed insights into the problems and challenges its products face in daily work. This has enabled KSB to tune its technical solutions precisely to what customers need. KSB’s sales engineers recognised that cutting back on processes in wastewater pumping stations would save considerable costs. In the end, they just had to convince their customers of this solution.

The city council of Oelde, located in the southeast Münsterland region in Germany, operates a public sewer system of about 280km in length for its 30,000 inhabitants. Nineteen pumping stations make the wastewater flow from suburbs such as Stromberg, Sünninghausen and Lette to the wastewater treatment plant, where 8,500 cubic metres are treated mechanically and biologically every day.

In addition to pump technology, wastewater pumping stations are fitted with components such as screens and strainers that mechanically pre-clean the wastewater upstream of the pumps. This prevents clogging or damage to the pumps. Wet wipes from hygienic applications, in particular, make wastewater transport difficult. Having to remove solids and

service the screens incurs extra costs.

KSB has further developed its Amarex KRT and Sewatec pump type series. A new impeller has been designed that can handle wastewater with a high solids content without clogging the pump. This means the pumping station operator can do away with any upstream components for mechanical pre-screening—a distinct advantage.

Once several prototypes were available, KSB started a field test where the pumps had to prove their worth in practice. Oelde’s Obstromberg pumping station was the first to use one of the newly developed pumps for a free trial operation. KSB supplied a Sewatec D-max and had it installed by engineers from the KSB service network. Installation was straightforward as the technically advanced pump was designed with standard dimensions. Only the hydraulic part of the pump has changed, and a larger suction pipe has been fitted.

In the one-month trial operation, Sewatec D-max 100-403 was used with the previously fitted upstream screen.

After running successfully for this period, the pump was then operated without the screen. And it worked: Even without mechanical pre-screening, the pump was able to handle coarse solids together with the wastewater without clogging. Twelve months after the trial operation had started, the Oberstromberg pumping station ordered a second Sewatec D-max. This additional pump has provided trouble-free operation together with the first pump since mid-2022.

The upstream screen, initially planned to be renewed, has since been completely removed from the pumping station, saving the operator a six-digit investment. A useful new technical development has eliminated a process that had been established for decades, including the associated costs for disposal and servicing.

REUSE BEERS MADE FROM TREATED WASTEWATER

XYLEM HAS TEAMED UP WITH partners in Bavaria to launch Reuse Brew, a beer crafted from high-quality treated wastewater. The initiative was created to raise awareness of the opportunities recycled water offers to help communities combat water scarcity in the face of climate change. Reuse Brew is the culmination of a collaboration with the Chair of Brewery and Beverage Technology at Technical University of Munich (TUM), the Chair

of Urban Water Systems Engineering at TUM, the city of Weissenburg in Bavaria and Xylem.

“Reuse Brew exemplifies the vast capabilities of water recycling in combating the pressing issue of water scarcity,” said Roxana Marin-Simen de Redaelli, Vice President of Central Europe and Nordics at Xylem.

Reuse Brew production leverages oxidative processes, ozonation and advanced oxidation with UV irradiation

and hydrogen peroxide, paired with sophisticated filtration and purification processes, including nanofiltration. These technologies effectively remove chemical and microbial contaminants through oxidation and adsorption, ensuring the beer’s quality.

Energy efficient pumps and the future of data centre cooling

With the accelerating demand for data centre capacity, the sector’s energy demands are growing at a colossal pace. The consequence, however, is carbon emissions that have surpassed those generated by the aviation industry, so it is essential that action is taken to reduce the industry’s energy usage. One solution is for data centres to adopt single-phase immersion cooling, which, when powered by high-efficiency pumps, can offer significant energy savings, as pumping specialist Crest Pumps explains.

Adata centre is a facility that houses and manages a large amount of data and the IT infrastructure required to process and store that data. It is the backbone of the digital economy, supporting critical organisations, from hospitals to small businesses, and can vary widely in size, power requirements, redundancy needs, and overall structure. Without data centres, many of our daily digital activities would not be possible.

The data centre market is experiencing significant growth due to the increasing demand for digital technologies and cloud computing. As more businesses and individuals rely on cloudbased services and storage, the need to store and process this data is skyrocketing. The market size stood at $263 billion in 2022 and is expected to advance at an annual growth rate of 10.9% during 2022–2030. This growth is driven by the digitalisation of corporate operations and the increasing use of streaming, internet usage, and, of course, AI.

This substantial growth brings about the challenge of making data centres more energy efficient. Data centres consume an enormous amount of electricity, often 100 to 200 times more than standard office buildings, due to the highpower requirements of the servers and cooling systems. The recent annual electricity report from the International Energy Agency (IEA) says that globally, data centres consumed 460TWh of electricity

in 2022, a figure that could rise to more than 1,000TWh by 2026.

HISTORY

Servers generate a lot of heat, and over the years, data centres have relied upon a variety of cooling methods to maintain the optimal temperature for equipment. In the early days, air conditioning units were the primary cooling method. However, these systems had limitations in terms of energy consumption and scalability, as they struggled to handle the increasing heat loads generated by modern equipment. As technology advanced, raised

Globally, data centres consumed 460TWh of electricity in 2022.

floor cooling systems emerged, with cold air delivered through perforated floor tiles. While this improved energy efficiency, cooling high-density server racks effectively was still challenging. Hot aisle/cold aisle containment is another commonly used practice, segregating hot and cold air streams to minimise mixing and improve cooling efficiency. Liquid cooling systems, such as chilled water or refrigerant-based systems, then became popular. These offered better heat dissipation capabilities but were complex and required additional infrastructure.

More recently, rear-door heat exchangers and direct-to-chip liquid cooling have been adopted for high-density computing environments, providing efficient cooling solutions for advanced data centres. However, these methods often require specialised equipment and maintenance, making them less accessible for smaller data centres.

SINGLE-PHASE IMMERSION COOLING

In modern data centres, best cooling practices focus on energy efficiency, temperature control, and humidity management.

Single-phase immersion cooling is a revolutionary method that involves immersing the data centre equipment in a fluorinert non-conductive liquid. This liquid efficiently absorbs and dissipates heat, providing a highly efficient cooling solution.

Single-phase immersion cooling offers superior cooling performance, reduced energy consumption, and improved reliability compared to traditional methods. Servers or IT components are fully submerged in a thermally conductive dielectric coolant. This coolant, which is in its liquid state, is circulated by a cooling distribution unit (CDU) to a heat exchanger outside the tank, where the heat is transferred to a secondary cooling circuit. The coolant is non-electrically conductive, ensuring it does not disrupt the servers’ function.

By eliminating the need for fans and air conditioning units, this cooling method significantly reduces energy consumption. According to industry experts, immersion cooling can achieve energy savings of up to 95% compared to traditional air-cooling systems with Power Usage Effectiveness (PUE) values as low as 1.03, resulting in substantial energy savings.

UNLOCKING THE POWER

The benefit of immersion cooling is that it eliminates the need for traditional air-cooling infrastructure,

reducing capital expenditure and operational costs. This cooling method relies on the principle of direct liquid-to-heat contact, providing a more efficient and effective cooling solution for data centres. The main benefits of single-phase immersion cooling include:

Environmental: Immersion cooling uses less energy and can decrease carbon footprints by 40%, real estate footprints by 30%, and water use by an astounding 8 million gallons per megawatt.

Space: Immersion cooling allows for higher server density, saving space in high-density data centres.

Safety: The coolant used in immersion cooling acts as a fire suppressant, reducing the fire risk in the data centre.

Scalability: As data centres grow, so do their cooling requirements. Immersion cooling is easily scalable and can accommodate future growth and changes in cooling needs.

Single-phase immersion cooling enhances the reliability of data centre equipment. By providing precise temperature control, it reduces the risk of equipment overheating and failure. This improved reliability ensures uninterrupted operation and minimises downtime.

OPTIMISING

Immersion cooling can achieve energy savings of up to 95% compared to traditional air-cooling systems.

fan-less design make it the ideal choice for immersion cooling and the model has already been successfully installed within Ali Baba and Intel systems. By reducing energy consumption, data centres can significantly lower their operating costs and improve profitability. Investing in high-efficiency pumps is a strategic decision that saves money and contributes to a greener and more sustainable data centre industry, which is vital when the sector is under increasing pressure to reduce its environmental impact and comply with energy efficiency regulations.

CONCLUSION

Pump alternatives for severe duty applications in hazardous environments

Robbie Graham, Business Development Manager for the Process & Chemical Solutions group at SPP-Rodelta – a strategic partnership between SPP Pumps and Rodelta –looks at the advantages of OH5 pumps, which include smaller physical footprints and lower weight, less downtime at installation, and reduced costs and carbon footprints.

The API 610 standard for centrifugal pumps is a watchword for safe pumping operations in the petroleum, petrochemical and natural gas industries. This stringent standard applies to pumps operating in environments where a spark would be catastrophic and is strictly enforced.

API 610 'overhung' (OH) pumps are used in a wide range of offshore and onshore applications. These include common applications such as crude oil export, process transfer, cooling water, and booster pumps,

as well as more specific onshore applications like flare knockout Drum (KOD) pumps, reflux, and oil recovery pumps.

These pumps are a common feature of the oil and gas fluid handling world, but that is not to say that they cannot be improved on to deliver more than just extremely safe, mission-critical performance. When designing pumps, hydraulic performance and safety are of paramount importance, but manufacturers are increasingly taking into account things like cost and environmental impact. While the OH2 pump is widely specified and used across

many scenarios that call for API 610, it is by no means the only choice.

In specifying and selecting pumps according to API 610 standards, all parties must be able to grasp the intricacies of the various pump designs outlined within the standard. This understanding is crucial for OEMs, EPCs, consultants, and end-users alike. While there may be overlap between designs, certain applications – particularly those where OH2 pumps are commonly specified – can significantly benefit from considering an OH5 design, especially when dealing with low

Hazardous Areas

NPSHa applications, lower temperature fluids (below 250°C) and lower head applications (less than 300m). There are several advantages of opting for an OH5 design in such scenarios: reduced footprint and weight, longer mean time between failures, and ultimately, diminished cost and carbon footprint. Moreover, the vertical, in-line configuration of the OH5 design offers additional benefits, such as simplified maintenance access and enhanced fluid flow efficiency, making it a compelling choice for a diverse range of operational requirements.

This has significant benefits, especially for offshore and prepackaged skid applications, where space is at a premium, and where they could be used to pump anything from boiler feed to oily surface water, crude oil and sour water to hydrocyclone feed and condensate recovery.

LIGHTER WEIGHT, SMALLER FOOTPRINT

The highly versatile OH5 pumps typically weigh around 25% less than a comparable horizontally mounted pump because they lack a large baseplate.

The standardised dimensional features of OH5 designs, compliant with BS4082, facilitate the straightforward design and provision of installation templates, which can be supplied prior to pump delivery. This enables the installation process to proceed concurrently rather than sequentially, with tasks such as grouting of the baseplate and welding of pipework completed ahead of the pump's arrival.

Such an approach offers several advantages to the customer: it allows the absorption of project overruns, streamlines the installation timeline, and provides a reusable method for preventing contaminants from entering the process system. Additionally, the installation dummy serves the dual purpose of keeping the line open for the process if needed, further enhancing operational flexibility and efficiency.

MEETING SUSTAINABLE DEVELOPMENT GOALS

Of increasing importance to manufacturers is adherence to the United Nation's Sustainable Development Goals. This is another area where the OH5 pump has a significant impact. Because it involves less steel in its configuration, there is already a reduction in carbon in its manufacture. Because of its compact nature, its installation requires less supporting concrete and steel and lightens the overall weight, important for LNG ships and offshore rigs. What's more, it costs less to ship and accounts for fewer emissions than larger, heavier OH2 equivalents.

OH2 OR OH5?

Of course, not every API 610 pumping application can be switched to an OH5. There are many scenarios where OH2 or other OH solutions will be optimal, such as higher-energy applications or applications with higher temperatures. But just because an application has traditionally used OH2, it doesn't mean that it always has to. From a safety, cost, size, weight, and environmental perspective, the OH5 alternative offers some compelling benefits. chevron-circle-right

Revolutionising sewage systems

With the chronic need to reduce sewage overflows, Emerson explores how its Flexim brand can offer an unintrusive option for measuring flow rates in sewage systems, which can, in turn, enable them to be optimised.

Britain’s water system, a relic of decisions made in 1856, has long struggled with sewage overflows, leading to many environmental and health concerns. The root of the issue lies in the widespread use of combined sewage systems, where rainwater and sewage intermingle, causing spills during heavy rainfall. The current infrastructure, designed by Sir Joseph Bazalgette in response to the 19th-century ‘Great Stink’, has become outdated and unable to handle the challenges of modern urbanisation.

The inherent flaw in combined systems is their vulnerability to overflow events. Although these were originally intended to be infrequent, climate change, population growth, and underinvestment have all exacerbated the problem. The need for a transformative solution is clear, and one promising technology is clamp-on ultrasonic flow measurement.

THE CHALLENGE

Combined sewage systems, prevalent in most major British cities, create a significant environmental hazard. These systems, designed to discharge sewage into rivers when it rains heavily, have become increasingly inadequate as the frequency of overflow events has risen. Bazalgette’s design, hailed as a marvel in its time, has struggled to keep pace with the demands of a rapidly growing population and changing climate.

The core issue lies in intermingling rainwater and sewage within the same pipes, leading to overwhelmed systems and frequent spills. As the problems persist, there is a growing realisation that a fundamental shift in sewage

system design is necessary to mitigate environmental impact and protect public health.

A TRANSFORMATIVE SOLUTION

Enter clamp-on ultrasonic flow measurement, a technology that offers a revolutionary approach to monitoring and managing sewage systems. Unlike traditional methods that involve intrusive installation of flowmeters inside pipes, clamp-on ultrasonic devices can be externally attached, eliminating the need for system shutdowns or extensive construction.

This non-intrusive solution delivers real-time data on flow rates, allowing for precise monitoring of sewage and rainwater volumes. The technology’s adaptability makes it a cost-effective option for retrofitting existing combined systems, providing a means to optimise performance without requiring extensive renovations.

OVERCOMING HISTORICAL CHOICES

While the historical decisions that led to the prevalence of combined sewage systems cannot be reversed, the integration of clamp-on ultrasonic flow measurement represents a step towards modernising and optimising existing infrastructure. This technology enables water authorities to gain comprehensive insights into system behaviour, identify areas prone to overflows, and implement targeted solutions.

The transformative potential of clamp-on ultrasonic flow measurement extends beyond the monitoring of combined systems. In new developments, where separate sewage and rainwater pipes are now favoured,

this technology ensures efficient operation and helps maintain the integrity of these modern designs. By preventing overflows and optimising the flow of sewage and rainwater, clamp-on ultrasonic flowmeters contribute to sustainable and resilient urban water management.

CHALLENGES AND OPPORTUNITIES

Implementing clamp-on ultrasonic flow measurement has its challenges. Overcoming historical underinvestment, regulatory hurdles, and industry-wide resistance to change will require a concerted effort from water authorities, policymakers and technology providers. However, the potential benefits – from reduced environmental impact and improved public health, to enhanced system efficiency – make it a compelling investment for the future. chevron-circle-right

Kiwa UK Regulation 4 (KUKreg4)

The Kiwa UK Regulation 4 Product Approval Scheme (KUKreg4)a robust method for demonstrating compliance with the Water Supply (Water Fittings) Regulations 1999.

sizing pressure booster systems: The parameters to consider

In larger buildings, the pressure supplied by water utilities is usually insufficient to supply the upper levels with enough water. The solution is pressure booster systems. These pump systems respond to fluctuating demand in water supply and adjust their output accordingly, so all consumer points in the building are supplied with the required minimum flow pressure at all times. KSB explores the factors which influence the sizing of such a system.

Usually, water utilities supply drinking water at an average minimum supply pressure of about 2 to 3.5 bar in the piping. This is generally enough to provide the furthest consumer point in a two-storey building with sufficient water. In higher buildings or when pressurereducing water meters, filters or water treatment systems are used in the inlet, the pressure is no longer sufficient – and the water only trickles out of the tap. In such cases, a pressure booster system (PBS) has to be installed to provide the pressure required.

In mathematical terms, according to DIN 1988 Part 500 (a standard for PBSs with frequency inverter; cascade-controlled systems are to be avoided in the future) a pressure booster system is required specifically when the sum of the pressure loss from geodetic height

difference (Δpgeo), the water meter pressure loss (ΔpWZ), the pipe friction and other individual losses [Σ(R · l + Z)], and the apparatus pressure losses (ΔpAp) (e.g. from filters or drinking water posttreatment systems) exceeds the minimum supply pressure pmin, v (or SPLN according to the latest standard) of the local water utility. Summarised in a formula:

SPLN < Δpgeo + ΔpWZ + [Σ(R · l + Z)] + ΔpAp + pmin, FL

The technical challenge is that the PBS has to provide a constant pressure at all times. This especially applies to times of peak demand. Today, new systems or replacements are designed as pressure booster systems with several variable speed pumps arranged in parallel on a baseplate. This means the electronically speed-

controlled pumps start up or stop depending on the demand. These pumps generally work in alternation: The next pump to start up is always the pump with the least operating hours; the next pump to stop is always the pump with the most operating hours. This ensures an even distribution of operating hours and prevents water from stagnating in the pumps.

In buildings with fire-fighting or fire-protection systems, the PBS provides a fast and reliable supply of fire-fighting water. In high-rise buildings it is essential for the wall hydrants on all storeys to be supplied with a suitable flow rate and the required minimum flow pressure. The fire-fighting lines further have to be separated from the drinking water system to protect the drinking water from contamination and other hygienically negative impacts.

THE REQUIREMENTS

Installing a pressure booster system is linked with stringent legal regulations that cover many different aspects. Here is an overview:

Drinking water hygiene

To continuously prevent microbial contamination of the water and ensure a high drinking water quality, the installation of PBSs is governed by the stringent guidelines of the drinking water regulation as well as by generally applicable regulations such as DIN EN 806, DIN EN 1717 and DIN 1988.

Operating reliability

DIN 1988 recommends an additional stand-by pump that is installed and ready for operation. This is why even small pressure booster systems have to be fitted with a minimum of two pumps. (This regulation does not apply to single-family or two-family houses.)

Installation room

According to DIN 1988-500, pressure booster systems have to be installed in suitable rooms, for example in a control room. The surface they are positioned on has to be level and of sufficient loadcarrying capacity. The room has to be frost-proof, and the temperature in the room must not cause the drinking water temperature to rise to 25°C or above, during stagnation, as stated in VDI 6023.

Further national and regional regulations apply to PBSs regarding the installation, connection types, commissioning, regular servicing, etc.

THE PARAMETERS

The precise sizing of a PBS for a larger building is far from trivial; it requires comprehensive understanding and know-how. For calculating the discharge pressure, the following basic formula is generally recommended:

ΔpP = pdischarge - p (in bar)

This means that the required discharge pressure (ΔpP) should

equal the start-up or set pressure at the peak flow rate downstream of the PBS (pdischarge) minus the available minimum supply pressure upstream of the PBS (pinl). So far, so simple. The complicated part is to determine pdischarge and pinl, which are influenced by a number of parameters:

• The minimum supply pressure of the water utility upstream of the PBS (at the water connection point of the house). This is also referred to as SPLN (lowest normal service pressure) in the standard.

• The minimum flow pressure at the hydraulically least favourable consumer point.

• The pressure loss caused by the height difference between the PBS and the highest consumer point (geodetic height difference) downstream and upstream of the PBS.

• The pressure loss of pipe friction and other individual losses downstream and upstream of the PBS.

selecting the right PBS variant and determining the total cost of ownership would go well beyond the scope of this article.

SUMMARY AND CONCLUSION

Installing a pressure booster system is linked with stringent legal regulations.

A pressure booster system is required whenever the minimum pressure supplied by the local water provider is insufficient. Pressure booster systems and their ancillary components must be designed and operated in such a way that neither the public water supply nor any other consumer units are interfered with – any degradation in the quality of drinking water must likewise be ruled out.

• The pressure loss of the water meter.

• The pressure losses of any apparatus installed in-between (e.g. filters, dosing equipment, mixing taps, waterfall shower head, etc.) downstream and upstream of the PBS.

For a rough calculation of the peak flow rate the type of building should also be considered: The water-use behaviour in schools is quite different to that in hotels, for example.

Calculating the exact required pressure (head) and flow rate (peak flow rate) downstream of the PBS,

Given the many options for pressure booster systems (cascade control, variable speed control of one or several pumps, direct or indirect connection) it is particularly important to select the right concept as early as possible in the planning phase of a project.

Retrofitting ageing pump systems offers energy savings

For the transition to high-efficiency, low-carbon buildings, retrofitting outdated heating, cooling and water systems with modern components such as variable speed drives and efficient pumps can offer significant opportunities, as Paul Winnett, Operations Director at Xylem UK, explains.

Retrofitting ageing buildings with high-efficiency pumps and drives offers one of the biggest opportunities to achieve smarter, more efficient buildings. This directly aligns with the International Energy Agency’s (IEA) Net Zero Emissions 2050 roadmap, updated in September 2023, which urges the global energy sector to double existing efforts to improve building efficiency.

Accelerated action will support the UK government’s net zero pathway, given that heating the UK’s 30 million buildings contributes to almost one quarter of all UK emissions. As a result of the Government’s Heat and Building Strategy, businesses across almost every sector are already taking steps to use less energy in response to rising utility bills and to achieve environmental goals.

Across the UK, many buildings, such as office blocks, shopping centres, hospitals, and hotels, were built between 20 and 40 years ago, and many have outdated heating and cooling systems that consume a lot of energy.

Simply replacing ageing equipment like-for-like is not the solution. The Government’s Heat and Building Strategy recognises this, saying: “Decarbonising heat and buildings will require the adoption of new, smarter technologies and practices”.

Widescale programmes to replace old equipment with high-efficiency technology for heating and cooling, as well as water pressure boosting, would accelerate decarbonisation goals and bring older buildings into a net zero world.

One way to significantly reduce the energy consumption of pumped systems is to switch to variable-speed technology. Older pumps typically run at a fixed speed, regardless of demand. Retrofitting with variable-speed drives enables the system to adjust to usage curves.

Due to the advanced technology involved, variable-speed solutions may have higher

upfront capital costs, but these costs will be offset over time by savings on energy bills. In addition, the operational and maintenance costs of variable-speed pumps are generally lower, as they are not running continually and experience less wear and tear.

For large commercial buildings, Xylem’s hydrovar X range of intelligent variablespeed pump drives, with high-efficiency IE5 motors, can cut the power needed to operate a pump by up to 70%. This reduction is achieved by ensuring the pump is only operating at the required speed, linked to the system’s demand variations.

The ability to adjust pump speed will immediately impact the energy consumption of large buildings, such as hotels, where demand for water and heating fluctuates throughout the day.

Take water pressure in a hotel; in a traditional system, the pumps would be on and the pressure constant. With a variable speed drive, the pumps could run at half their speed during periods of low demand, such as lunchtime when fewer people are in their rooms, and increase as guests start checking in and using facilities.

As the evening continues and demand rises, the system will automatically adjust to ensure constant pressure throughout the building. To achieve this, the system takes pressure or flow readings from sensors to adjust the number of pumps running and their speed, ensuring demand is met while maximum operating efficiency is delivered.

Of course, while retrofitting is essential to decarbonise existing buildings, using low-carbon technologies in new builds is a must – the Government’s Future Homes Standard comes into effect in 2025, bringing a set of rules to ensure new homes produce less carbon.

For contractors who are value engineering a project, using cheaper technology may reduce the capital outlay, but if they consider the whole lifecycle of the product, high-end low-carbon technology is likely to be more efficient and deliver the most value because of the significant long-term energy savings. chevron-circle-right

We urgently need a government-led industrial policy

Make UK CEO Stephen Phipson, who recently addressed the Europump annual meeting at the request of the BPMA, explains why his organisation is calling on whoever is in government after the election in July to ensure a modern, long-term industrial policy is announced within the first 100 days.

Manufacturing holds a vital place in the UK economy, contributing £224bn of Gross Value Added in 2023. It’s a major driver of innovation, with 43% of R&D investment stemming from the sector. Notably, it’s a significant contributor to job creation, employing 2.6 million people nationwide. Moreover, manufacturing offers solutions to pressing economic challenges like climate change and the volatility of global supply chains.

This sector is renowned for its high-skill, high-wage nature, boasting average wages 9% higher than the national average. Across the length and breadth of the country, manufacturing businesses of all shapes and sizes are leaving their mark. They’re not just factories churning out goods but are engines of local prosperity, injecting life into communities and driving economies forward. The sector’s heartlands are primarily in rural and regional areas that are often overlooked by the spotlight of London and the Southeast. These companies are the backbone of regions that are eager for growth.

But it’s not just about jobs; it’s about skill-building too. Every year, nearly 50,000 engineering and manufacturing apprenticeships are offered by UK manufacturers, nurturing the next generation of talent and keeping skills alive in communities. They’re not just places of work; they’re the heartbeats of towns, fostering a sense of belonging and opportunity. They attract investment, bring innovation, and shape the identity of the places they call home.

And they’re not stopping there.

Manufacturers have their eyes set on the horizon, aiming to ride the wave of a netzero economy and embrace cutting-edge technologies like AI and digitalisation. Their goal? Nothing short of becoming the most innovative economy on the planet. They’re not content with the status quo; they’re striving for a future where sustainability and prosperity go hand in hand.

The sector has demonstrated resilience and adaptability in recent years, setting the stage for further growth in the future. Ambitious plans aim to boost UK competitiveness by increasing manufacturing’s contribution to GDP from 10% to 15% by the end of the next decade.

Achieving this target would inject an additional £142 billion into the UK economy, fostering longterm domestic and foreign investment.

and that is why Make UK’s manifesto published ahead of the election is calling for a modern, long-term industrial policy to be announced within the first 100 days. The UK is an outlier in not having one, which is the Achilles heel of the UK economy. In particular, this strategy must embrace a skills revolution throughout the education and training system to provide future talent, as well as the upskilling and re-training of the current workforce.

In particular, this strategy must embrace a skills revolution throughout the education and training system.

By 2050, UK manufacturers aim to achieve net-zero emissions, prioritising energy efficiency and industrial innovation every step of the way. We envision a world where every factory operates without a single sheet of paper and where automation fuels productivity and progress. To achieve all of that, we need support that compares to what other countries and governments are giving their manufacturing sectors around funding, regulation and guidance.

As such, we are now at a tipping point,

Such a vision is essential given the huge changes in the policy landscape, the need to shock the UK economy out of its anaemic holding pattern and take advantage of the opportunities provided by rapidly accelerating technologies, investment in infrastructure and the move to a greener economy.

A policy framework for the economy beyond 2030 is also essential to counter the march of the US and China in green technologies in particular, as well as the need to make the UK as attractive a destination as possible for investment, given the rate at which other countries are gearing up.

If the next Government were to commit to delivering such a strategy and make it a cross Government priority then I am confident that the sector can lead the economy into the 2030s and beyond. chevron-circle-right
