reject water stream Applications

  • Using evaporation to dewater Reverse Osmosis reject waste streams

    Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the...

  • Electrodeionization

    The Fractional Electrodeionization (FEDI) process is an advancement of conventional EDI. The patented dual voltage process allows for a higher flexibility and tolerance to inlet water conditions, thus lowering the risk of scaling, and improving the plant& design economics and reliability. By incorporating a two-stage separation process with different voltages the FEDI process is able to: Achieve a higher hardness tolerance by having distinctly different concentrate chambers with separate reject streams and thus...
