Reverse osmosis energy recovery system

  1. Jan 26, 2013 #1
    I want to know the possibility for reducing pressure of reject Brine fluid below the inlet pressure of raw feeding water to RO by a pressure exchanger / Energy recovery turbine in Reverse osmosis system. If its possible, how it works? Please help me in this regards.
    Thank you

    A question like that needs a lot more information.

    what is the max pressure, how much pressure drop?

    Those are just a few question if possible can you post some system drawings.

    Please go through the following link.

    note the inlet & outlet parameter of energy recovery turbine. I want to know, how is it possible to lower the pressure at point 5 below the pressure at point 2.

    Does anyone knows the internal arrangement of the same?

    kindly help me to understand.
