The disposal of concentrate from RO systems presents challenges and typical methods include deep well injection, surface discharge, or sanitary sewer. The volume of water generated or the high salinity impinge on the economic viability of these methods. One accepted method of reducing the volume discharged is to apply additional membrane treatment to the RO concentrate to achieve additional recovery. The success of this method depends on the chemistry of the feed source, antiscalant inhibition capabilities, and good system management.
