Microscreen filter minimises power consumption

Microscreen filter minimises power consumption Hydrotech’s HSF 2600 microscreen filter features a large filtration area. It is designed as an economical machine for municipal water, industrial water and wastewater treatment. The HSF 2600 cuts down on energy and increases efficiency. The water
to be treated flows into the filter drum. A patented design leads the water into the disc segments. The flat filter panels in each disc segment catch the solids and divert them to a collection area, allowing filtered water to pass through. The design of the filter
CleanBallast system receives Type Approval RWO Marine Water Technology, a Veolia Water Solutions & Technologies company, found that in testing under extreme conditions, such as high sediment concentrations, CleanBallast exceeded the IMO test requirements. CleanBallast consists of a mechanical filter process and a special disinfection unit. The system, which can operate not only in seawater but also in waters with a low salt content, is offered for various
capacities and assignments and for new building and retrofitting. Niels Stolberg, president and CEO of Beluga Shipping GmbH, said: “We are very satisfied with the performance of the CleanBallast systems, which already enable us to implement the loading and discharge of ballast water in conformity with the D2 standard of the IMO.” www.rwo.de
CEDI module offers high flow rates Siemens’ IonPure LX-45Z continuous electrodeionization (CEDI) module is designed for industrial post-reverse osmosis (RO) water purification. The module incorporates Siemens’ non-chemically regenerated CEDI technology, while incorporating less expensive, industrial chlorinated polyvinyl

chloride (CPVC) materials of construction. By adding additional CEDI cells, the module is capable of higher flow rates for RO permeate polishing without the cost premium imposed by stringent pharmaceutical material compliance. The 50% flow capacity increase per module significantly reduces the number of pipe connections needed in systems using multiple modules. This results in simplified water system integration, ease in mounting to a polishing skid and lower capital cost. The IonPure LX-45Z offers benefits to customers in the hydrocarbon/ chemical processing, power, electronics and laboratory markets, such as a 50% higher flow rate in a single module, compared to earlier LX modules. The LX-45Z module also offers a compact design, costeffective materials and robust, double o-ring construction. www.siemens.com

System design tool simplifies process Porex Filtration has created the Porex TMR-PRO System Design Tool to help OEM systems integrators properly design a tubular membrane filtration system using the Porex membranes. The tool minimises the iterations normally needed to design such systems, and simplifies the overall design process. The TMF design tool has the capability of determining the chemistry for the removal of a variety of heavy metals in the Pretreatment Chemistry portion
of the tool. The System Design portion of the tool will lead the user to develop a workable TMF system and the printed report will summarise the results as well as provide a printed copy of the TMF module specifications. The user may select either English or Metric units to be displayed in the programme. The programme includes features to save the data to a file for later recall and to provide a printed report and/or a report in Adobe PDF format. www.porexfiltration.com
Module removes suspended solids Toray’s Membray submerged membrane bioreactor (MBR) module consists of flat sheet PVDF membranes which are caste on a polyester, non-woven fabric base layer. The MBR module is comprised of an element block and an aeration block. The element block contains the PVDF membrane filter elements stacked at equal intervals. Each element is connected via a polyurethane tube to a permeate water manifold. The aeration block consists of air diffusers used to supply air to the MBR module. Using membranes with a high density distribution of 0.08 μm nominal pores to separate sludge ensures an extremely high quality for treated water free from suspended solids. The membranes can retain activated sludge at
high concentrations, allowing BOD (Biochemical Oxygen Demand) as well as nitrogen to be removed more efficiently with minimal clogging. The module can be submerged directly into an activated sludge tank for combining biological treatment and membrane separation. It eliminates the secondary sedimentation process and reduces the activated sludge tank size. The flat sheet MBR plate-and-frame configuration is more resistant to fouling than the hollow fibre membrane configuration, resulting in fewer chemical cleaning requirements. The reduced module fouling from human hair and other obstructive substances allows for coarser screening as a pre-treatment process. www.toraywater.com
