Water & Wastewater Treatment

PRODUCTS AND PROCESSES 36 Water & Wastewater Treatment March 2014 wwtonline.co.uk Doosan secures mining filtration contract Doosan Enpure has secured a £10.4M contract to design, procure and supply a filtration plant at the world's largest copper mine, in Chile. The Doosan Enpure scope for the Escondida Water Supply Project includes design, supply and installation of a 446,000m3/d pre-treatment plant, comprising of 60 rubber- lined pressure dual media filters, www.doosan.com Chilean copper mine Sludge Finder improves electricity generation The installation of eight Sludge Finder 2 interface monitors from Pulsar Process Measurement has helped increase electricity generation at Severn Trent Water's Stoke Bardolph sewage treatment works. Pulsar says the installation, part of a wider process improvement project, has helped the utility to reliably and consistently measure the sludge blanket level to optimise the pump operation. This ensures that the maximum amount of sludge of the right density is efficiently transferred to the digesters. www.pulsar-pm.com It's all in the mix For turbulent flow applications where a high degree of mixing is required in a compact installation space, Chemineer says its new Kenics UltraTab is designed to bring key benefits to water treatment and desalination plants, as well as chemical processing. Independently tested by BHR, the company says UltraTab provides the lowest pressure-drop per degree of all mixing models, enhancing energy efficiency of the process. www.chemineer.com UltraTab enhances process Open air benefits of water level radars Radar level sensors are being installed throughout the East Riding of Yorkshire Council drainage area. The council has undertaken a replacement programme for existing ultrasonic and pressure sensors, as well as installing new measurement points. This has been enabled via Vega's non-contact water radar level sensors. The company says measurement is unaffected by wind, rain or surface turbulence. www.vega.com/uk Actuators boosts biogas production Rotork's Schischek ExMax explosion- proof actuators have been selected to assist the production of biogas at the city's largest wastewater plant, Klaerwerk Gut Grosslappen.The ExMax actuators have been installed in the digester and fermentation tanks where all electrical equipment must be approved for use in hazardous areas. Six actuators have been installed in each tower for the operation of air dampers to balance the inside temperature with ambient temperatures. www.rotork.com Hydrok feature added to SUDS software XPSolutions' sustainable drainage modelling software, Micro Drainage, has been updated with the addition of Hydrok's HydroSlide flow control units. The software allows users to model existing drainage networks and identify areas at risk of flooding. David Fortune of XPSolutions said, "Micro Drainage 2014 contains significant improvements including a redesign of the 3D navigation, shape file import and rainwater harvesting tools, as well as the incorporation of new flow controls including Hydrok's Hydroslide." www.hydrok.co.uk Hydok's HydroSlide University purchases discrete analyser Lake Superior State University in the US recently purchased a Seal AQ1 discrete analyser for its Environmental Analysis Laboratory. This advanced instrument was purchased to analyse local, regional and national water quality samples. It also helps provide the university's students with practical experience of working with an analyser. www.seal-analytical.com Crowcon moves and expands facility Gas detection specialist Crowcon has celebrated the official ground-breaking for its new 3,700m 2 facility at Milton Park, Didcot. The facility, which is managed by MEPC, will house all existing functions as well as provide extensive customer training and product demonstration facilities. It also includes an additional 30% of manufacturing space and a full service calibration laboratory. www.crowcon.com Munich installation Crowcon and MEPC directors celebrate Seal AQ1 analyser Sludge Finder 2 River Aire installation
