      Reverse Osmosis Equipment for Power Generation
      Primary power generation Reverse Osmosis application is boiler feed water pre-treatment
      Downstream of clarification and filtration
      Upstream of demineralization polishing
      Reverse Osmosis equipment performance directly impacts demin performance and acid/caustic usage.

      Reverse Osmosis Equipment Definitions
      Osmosis
      Pure water diffuses from the dilute side to the concentrated side of a semipermeable membrane.
      Reverse Osmosis
      High pressure is applied to the concentrated side of the membrane and pure water flows to the dilute side.
      Net Driving Pressure
      The pressure applied to the membrane to create the reverse osmosis. Typically 200 – 450 psi.

      Industrial Reverse Osmosis for Power Generation
      RO Stage
      A series of elements linked together such that the reject (concentrated) water from stage 1 becomes the feed water for stage 2.
      This is done to reduce wastewater and to increase the total recovery from the RO array.

    • A Two Stage RO System for Power Generation

    • Reverse Osmosis for Power Generation
      RO Pass
      An arrangement of elements where the permeate from pass 1 becomes the feed water of pass 2.
      This is done to produce a final product that is more pure than what can be achieved using only one pass.
