  • The safe use of cationic flocculants with reverse osmosis membranes

    Abstract Flocculants are used in combination with coagulants to agglomerate suspended particles for removal by filtration. This technique is used extensively in all types of surface waters to reduce the silt density index (SDI) and minimise membrane fouling. Although organic cationic flocculants are particularly effective, their widespread use in membrane applications is limited ...

  • Improvement of Electrodeposition Paint Processes with Reverse Osmosis

    Abstract For over 15 years, membrane separation processes have been very effectively utilized as essential components of electrodeposition (ED) paint processes. ED is the accepted method of applying the undercoat paint layer to new automobiles and appliances. As cross-flow membrane and ED paint technologies mature, new applications combining the two have been developed. A major American ...

  • New developments in filter cartridges for reverse osmosis pre-filtration

    Reverse osmosis (RO) pretreatment systems are designed to reduce suspended solids to a level that will provide the most suitable conditions for the performance of the membrane system. Depending upon the quality of the feed water, pretreatment may include settlement, clarification, multi-media filtration, and chemical treatment. However, sediment pre-filtration is always required to ensure that ...

  • Size fractionation characterisation of removed organics in reverse osmosis concentrates by ferric chloride

    Reverse osmosis membrane separation is the leading method for manufacturing potable purified water. It also produces a concentrate stream, namely reverse osmosis concentrates (ROC), with 10–20% of the water, and almost all other compounds. One method for further treating this stream is by coagulation with ferric chloride. This study evaluates removed organics in ROC treated with ferric chloride. ...

  • Membrane Selection and Optimal Ammonium Nitrate Chemistry for Reverse Osmosis Treatment of Explosive Wastewater

    A process for manufacturing explosives produces an ammonium nitrate-laden wastewater, which can be successfully treated with reverse osmosis (RD). Key to RD use is balancing the competing waste solution chemistry requirements of the two target solutes, to enhance the performance of the particular RD membrane chosen. While the EPA requires only the reduction of the N03 and NH4+ discharge levels ...


  • VSEP takes reverse osmosis where it has never been before, further concentrating RO reject (brine) streams to increase overally recovery to 99%.

    Conventional spiral wound membrane systems using reverse osmosis or nano-filtration membranes are increasingly being used to treat well water from underground sources to supplement local drinking water supplies. Many of the remaining underground water sources are 'Brackish' water sources where the dissolved solids can be 5,000 mg/L or even higher. One of the difficult engineering aspects of ...
