20 WET NEWS MAY 2019 | wwtonline.co.uk S elwood has won an exclu- sive contract to continue to hire pumps and pipe- work to Northumbrian Water for a minimum of three years. The contract, which comes with the option to extend for a further two years, was awarded following a competi- tive tender process through which Selwood demonstrated expertise in comprehensive pump and pipework solutions. Richard Brown, managing director at Selwood, said: "We are delighted to have won this contract to continue working with Northumbrian A PEM Ltd, the independ- ent environmental con- sultancy specialising in the aquatic environment and remote sensing, has under- gone a management buy-out backed by private equity ƒ rm WestBridge Capital. The deal has seen West- Bridge invest £9.8 million in a combination of equity and loan notes, which will sup- port the company's growth ambitions as it develops com- plementary service lines to support its clients' needs. Following the transaction, business founder Dr Keith Hendry will retire, while Dr Adrian Williams and Dr Stu- art Clough, who have been central to the growth of the business over the past dec- ade, will continue to take the company forward. They will be supported by an experienced executive B luewater Bio's high-rate multimedia ƒ ltration technology FilterClear has been selected for three fur- ther plants by three diŽ erent water companies to achieve compliance with tighter phos- phorus consents. In each case, Bluewater Bio will provide a fully automated tertiary solids removal (TSR) plant. The treatment solutions provider will work with Severn Trent's capital delivery frame- work partner, Costain/Stantec (CiM6), in providing a TSR plant at Ledbury WwTW, which marks the company's ƒ – h contract with Severn Trent for phosphorus removal. For United Utilities and Welsh Water, Bluewater Bio will deliver TSR plants at Barton WwTW and Dyserth WwTW respectively. Mott MacDonald Bentley is in both cases the nominated Tier 1 deliv- ery partner. Bluewater Bio's Fergus Rooksby said: "We are Water as valued partners. "We work hard to meet and exceed the requirements of our clients and partners by providing safe, robust, and reliable commercial pumping solutions and investing in our products, people and resources. We are pleased that this has been recognised by Northumbrian Water in one of a string of recent con- tract wins." Northumbrian Water pro- vides water and sewerage services to 2.7 million people in the North East of England, making it the biggest water supplier in the region. team who will benefit from the wider share ownership that the transaction has allowed. "We are delighted to con- clude this deal," Dr Williams said. "As well as enabling us to develop a wider suite of spe- cialist services across the UK, it allows us to exploit the huge growth potential pre- sented by the US offshore wind market." Established in 1990, APEM provides environmental con- sultancy, laboratory services, field surveys and remote sensing capabilities to a range of sectors including water, power, engineering, construction and transport. Clients include water com- panies, government bodies and regulatory authorities, such as the Environment Agency and Defra. delighted that on the back of FilterClear's impressive results in meeting low P consents at other sites across UK that Sev- ern Trent have awarded us our ƒ – h contract for their treat- ment works at Ledbury WwTW. "In addition, securing two new clients in Welsh Water and United Utilities is further testament to FilterClear's growing reputation as an ideal solution for a chemical dosing approach to low phosphate concentration consents. We are seeing that the technology is not only eŽ ective in meeting P consents below 0.5 mg/l TP, but also performs well on works that have a variable sus- pended solids load proƒ le. "Indeed, FilterClear's abil- ity to handle higher levels of inŸ uent solids makes it an ideal candidate for trickling ƒ l- ter works, or on the back-end of secondary processes that are prone to occasional sus- pended solids peaks." WHAT ARE THEY? Atlas Copco Power and Flow has completed its portfolio of WEDA electric submersible dewatering pumps, by launching pumps for drainage and sludge applications and adding a completely new range for slurry applications. The range now comprises three families: the expanded WEDA D for dewatering, WEDA S – also expanded – for sludge, and the entirely new WEDA L slurry family. WHAT'S GOOD ABOUT THEM? Aside from optimising their performance, a lot of focus has been given to make the pumps lighter, enhance electrical safety, improve the seal design and ease installation. All pumps in the D and S range are available with WEDA+ features, which include phase failure protection, rotation control, thermal switches and a 20 m cable with phase shifter plug for all 3 phase pumps. The WEDA+ features are also available as an option on the L range. WHAT DO THEY SAY? "The WEDA pumps can handle flow rates of up to 16,500l/min, with power ratings up to 54kW," Hrishi Kulkarni, product manager for Atlas Copco's power and flow division, said. "Accordingly, they make ideal dewatering solutions across many, diverse applications within the construction, industrial, emergency and maintenance sectors. Now, our ubiquitous coverage has been highlighted by these latest additions to the range, as they make our portfolio complete." Taskmaster TM8500 Grinder The Taskmaster TM8500 is a high-performance, twin-shaft grinder that provides powerful size reduction capabilities, easy maintenance and exceptional durability. The unit features cutter cartridge technology that increases unit strength completely and eliminates the need for cutter stack re-tightening. The Taskmas- ter can be successfully installed in sewage treatment plants, sludge lines, pumping stations, roadside or runway sanitary facilities, institutional waste, or small solid waste applications. They reduce pump ragging and problems with downstream equipment by š nely reducing such solids as rags, plastics, wipes, paper, dispos- ables, fabrics, wood and bottles. The unit is supplied for open channel or in-line applications. Qdos Chemical metering pumps Qdos chemical metering pumps, also made by WMFTG, cover flows from microlitres up to 2,000 litre/ hour and are widely adopted for water treatment applications where they are handling disinfectant chemicals and flocculants 24/7. Like the Bredel and APEX pumps (see left) they are certiš ed by the NSF, which allows them to be sold across the USA and is also a respected stand- ard in other countries. 'NSF/ANSI 61: Drinking Water System Components – Health E§ ects'¨certiš es that the chemicals and materials used in producing drinking water are safe and will not have negative health e§ ects. The standard ensures that components of the process will not add contaminants that will cause health or regulatory problems. Bredel and APEX pumps A number of advanced pumps o§ ered by¨Watson-Marlow Fluid Technology Group (WMFTG)¨have been certiš ed to the¨NSF/ANSI 61 standard, a move that provides further assurance for water industry companies seeking safe and accurate chemical metering. Watson-Marlow Models in the¨Bredel¨and¨APEX¨ranges have become the š rst chemical metering hose pumps worldwide to achieve¨accreditation for drinking water chemicals. The certiš cation covers APEX10, 15 and 20 hose pumps (with EPDM hoses), APEX28 and 35 (with EPDM and NR hoses) and Bredel 10 to 50 (seven models) with EPDM and NR Endurance hoses. As a result, water industry customers can now deploy¨certiš ed hose¨pumps in applications with flow rates up to 17,500 l/h and discharge pressures up to 16 bar.
