  • Ceramic membranes for water treatment

    Ceramic membranes, different in pore size and membrane material, were applied to remove particulate and dissolved matter from different spent filter backwash water types as well as from dam water. The study was conducted in pilot scale under conditions typical for waterworks at a dam water treatment plant. A comparison of different ceramic membranes implied that total membrane resistance was more ...

  • Key issues of ultrafiltration membrane water treatment plant scale-up from laboratory and pilot plant results

    Industrial-scale ultrafiltration (UF) membrane systems have gained wide acceptance for producing safe drinking water. Laboratory and pilot plant studies are often carried out prior to the design of full-scale water treatment plants. Emphases are laid on how accurately these laboratory and pilot plant studies represent actual industrial-scale systems and the limitations. A case study which ...

  • Newport water treatment plant improvements - new membrane treatment facility case study

    City of Newport Newport, Oregon, USA HDR provided design and construction engineering services for a new water membrane filtration facility in Newport, Oregon. The plant's capacity was upgraded from 4 to 6 million gallons per day (MGD), expandable to 10 MGD. The new treatment system design includes an intake pump station, a pressurized flocculation system, membrane ...


  • Occurrence of N-nitrosodimethylamine precursors in wastewater treatment plant effluent and their fate during ultrafiltration-reverse osmosis membrane treatment

    The formation of N-nitrosodimethylamine (NDMA) is of major concern among wastewater recycling utilities practicing disinfection with chloramines. The NDMA formation potential (FP) test is a simple and straightforward method to evaluate NDMA precursor concentrations in waters. In this paper we show the NDMA FP results of a range of tertiary wastewater treatment plants that are also the source for ...

  • Heavy Industry Plant Wastewater Treatment, Recovery ang Recycle Using Three Membrane Configurations in Combination with Aerobic Treatment

    ABSTRACTIn the late 1990’s a major diesel engine manufacturing plant began evaluation of wastewater treatment technologies that would improve the quality of wastewater discharge, would produce treated effluent of reduced oil and grease, BOD and COD load suitable as feed to their sanitary waste biological treatment plant, and eliminate the costs and risks associated ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Pilot plant trials: management of membrane concentrate

    In surface water nanofiltration (NF) for drinking water production, 15 to 25% of the feed is rejected by the membranes. Two complementary approaches are investigated in order to manage concentrates. On one hand, an additional NF stage allows an increase in the yield of drinking water production from 85 to 94%. Thirty-days filtration cycles are achieved. Conductivity, natural organic matter (NOM) ...
