Using proprietary Multifiber PET�� Technology, hollow fibers are entwined with a spacer yarn that provides additional membrane stability. UV system treats 215,000 m3/d with only foUr lamps California-based NeoTech Aqua Solutions, manufacturer of ultraviolet (UV) water-treatment systems, announced on 21 November 2011 a UV system to treat 5.7 MGD (215,750 m3/d) with only four lamps. The Magnum UV disinfection system utilizes the same patented high-reflectivity chamber that has been NeoTech Aqua���s core technology since 2008. ���By reflecting over 99% of the UV we produce, we all but eliminate the loss of valuable UV energy to the chamber walls ��� a problem that is typical of stainless-steel chambers and those using aluminum or quartz reflectors,��� says Dr. Randy Cooper, NeoTech Aqua���s chief technology officer. ���The high efficiency of Magnum translates directly to power cost savings, significantly lower maintenance requirements, a small fraction of the bulbdisposal requirements, and a more environmentally responsible operation.��� Each unit uses low-pressure amalgam lamps for maximum UV output per kilowatt. Using patented ReFleX��� technology and a NIST-traceable UV intensity-monitor, clients can be provided with 100% Dosage Assurance���, so that disinfection requirements can be reliably met without post-UV assays. CeramiC membranes Can redUCe wastewater filtration Costs New ceramic membranes for water filtration and purification for use in industrial wastewater treatment processes are being developed by Morgan Technical Ceramics. Morgan believes that its new products will help industrial operations to be more environmentally friendly and efficient. The reliability of the ceramic membranes enable businesses to reduce maintenance and energy usage and make associated cost savings. Traditionally polymer or ceramic tubular membranes are currently used to clean and conserve water in industrial wastewater applications. However, polymer systems need replacing regularly, especially if not tailored to the application, and ceramic tubular membranes need high water flow rates to operate effectively. Morgan claims that its porous ceramic disc membranes have many benefits compared with polymer substrates. The ceramic is robust and gives high performance where high temperatures and aggressive cleaning chemicals are prevalent. The filters can withstand the harsh environments found in wastewater treatments and as a result, they are long-lasting and do not need replacing as often as plastic alternatives. They do not need the high flow rate required for current ceramic tubular membranes, saving energy and costs associated with pumping water at lower flow rates. Morgan Technical Ceramics has the ability to manufacture components to highly complex geometries and to tight tolerances and its ceramic membranes are just 20 microns thick. The porous ceramic membrane systems are ideal for use in ultrafiltration applications that collect bacteria and purify industrial wastewater allowing it to be reused in the plant or safely discharged into the environment. modern water Completes toxiCity-monitor pUrChase UK-based Modern Water plc announced on 9 December 2011 completion of its acquisition of Strategic Diagnostics Inc���s (SDIX) Water Quality division, including its Microtox�� toxicity testing technology. This acquisition gives Modern Water a base for its business operations in the Americas through its newly created Modern Water Inc. It represents another strategic step for Modern Water���s existing MW Monitoring business, which includes the Cymtox continuous toxicity monitor and the Cogent portfolio of advanced trace metal analysers. Modern Water is also developing its Manipulated Osmosis membrane desalination technology via projects in Oman and Gibraltar. The STX Microtox�� rapid-toxicity detection platform allows customers to rapidly, cost-effectively and accurately identify the presence of hazardous chemicals, including those from the USEPA Priority Pollutants List, and other contaminants that can compromise human or environmental health and safety. aqUateCh aCqUires German water-polishinG liCenCe Aquatech International Corporation of the USA has finalized a cooperation agreement with WasserBauGesellschaft Kulmbach GmbH (WBG), a leading water technology company based in Germany, to hold the exclusive North American license for WBG���s RSR Plus�� Condensate Polishing Technology. Aquatech describes the technology as the most advanced condensate polishing technology currently available, which will expand its range of offerings to customers in the power generation, semiconductor, electronics and chemical industries. RSR Plus is an optimized process for the transport, separation and external regeneration of ion-exchange resins. RSR Plus is applied when regeneration of resins in the filter vessel is not possible or not desired. l February-March 2012 | Desalination & Water Reuse | 37 |
