SHOWCASE H2O InnOvatIOn unveIlS MF/uF rack and packaged MBr Canada's H2O Innovation Inc has introduced a module rack design for microfiltration (MF) and ultrafiltration (UF) membranes, which will accommodate modules made by other manufacturers. The company has also launched a second generation containerized and dual-train membrane bioreactor (MBR) dedicated to wastewater effluent. The FiberFlexTM MF/UF skid provides interchangeability between the most popular hollow-fiber membrane modules supplied by Dow, Hydranautics, Toray, Asahi and GE, says H2O Innovation. Depending on the membrane product to be used, the correct module holding plate is selected, and the bottom support beam holding the modules is moved to the correct height and mounted using a set of predrilled holes. The company expects to commission its first FiberFlex installation by the end of this year. Also on 25 July 2013, H2O Innnovation launched a 100 m3/d MBR package solution that can meet or exceed typical wastewater treatment effluent regulations throughout North America. The combination of an activated sludge process with membrane filtration leads to a versatile system that can be used for many different applications to provide superior solids removal while minimizing sludge production and enhancing nutrient removal. grundFOS puMp SySteM BOOStS FOr rO and uF Danish pumpmaker Grundfos has launched a new range of lightweight booster modules for high flow and pressure applications, including reverse osmosis (RO) and ultrafiltration (UF). The company has also released two new BMS pump systems for desalination Focus on simplicity for the booster modules has removed maintenance-heavy components and resulted in easy access to all vital parts. Combined with a permanent magnet motor, the efficiency of the pump has been improved by up to 5% and the weight reduced by more than 75%. The BMS hs booster modules are designed for industrial and municipal water treatment systems. The processes include: RO systems; UF systems; Filtration systems; and Pressure-boosting systems and water supply. The new Grundfos BMS hs has passed rigorous tests in different environments. Among these is a desalination plant on Lipari Island in Italy, where the design improvements and performance of the system impressed the customer. The new desalination pump systems are the BMSX and BMST. The BMSX is designed for seawater and brackish water desalination. It consists of a BMS hs pump, a BMS hp pump and an isobaric pressure-exchanger with an efficiency of up to 98%. The system has the following features: l Capable of delivering 1,500 m³/day with an energy consumption starting as low as 2 KWh/m3 of produced water, l Components made of super duplex stainless steel, polymer and ceramic, making the module extremely resistant to its operating environment l Compact design and a very small footprint. The BMST booster systems consist of a BMS hs and a Pelton turbine. This power pack makes it possible to deliver the same | 36 | Desalination & Water Reuse | August-September 2013 The Grundfos BMS hs booster performance as with a standard centrifugal pump and thus save up to 35% of the pump's total power consumption. BMST features include: l Corrosion resistant material: all critical components are super duplex stainless steel, l Capable of handling aggressive liquids such as brackish water and seawater l to integrate into skid-mounted systems. Easy reuSe applIcatIOn FOr twO addItIOnS tO uv range Two new additions to the Xylem range of medium-pressure ultraviolet (UV) disinfection systems are said by the manufacturer to be particularly suitable for wastewater reuse, as well as fish-farming and swimming-pool applications. Xylem's new WEDECO Quadron 600 and 1200 units manage flows of up to 1,350 m³/h and 2,100 m³/h (8.6 and 13.3 MGD) respectively. A standard feature across the range is the OptiCone flow diverter, which promotes ideal hydraulics with very low head-loss regardless of inlet piping conditions. The series offers a comprehensive proof of performance, as it is validated according to the US EPA's UV Disinfection Guidance Manual (UVDGM, 2006) and certified to the German/Austrian Technical and Scientific Association for Gas and Water (DVGW/ÖNORM). The UVDGM-validated solution can be tailored to meet different requirements depending on the individual water or wastewater treatment situation. SMall rO deSalInatIOn unIt can Be tOwed By 4x4 A desalination unit that can be mounted on a small trailer and towed by a 4x4 vehicle is being marketed by UK company Water From Water Ltd. The Hydro Voyager™, which includes filtering, reverse osmosis (RO) and ultraviolet (UV) disinfection to produce 5 m3/d of potable water from almost any source including seawater, was developed by David Jukes of Potable Water Solutions, drawing on his experience in installing desalination plants in countries including Saudi Arabia, Oman, Libya and the Caribbean. "My aim was to make a system which was both portable and affordable," he explained. "The main challenge was in sourcing parts which were sufficiently small to create a unit which would fit on a small trailer." The resulting unit, which runs off a small generator on the trailer has been developed for use in communities where fresh drinking water is currently unavailable, and also has applications for small-scale commercial ventures and in disaster relief. A submersible pump draws the water from any available source, including brackish and saline sources. The water passes through filtration units and carbon polishing, which
