Reverse osmosis purification system

摘要: A reverse osmosis water purification system for providing potable from a municipal or other source containing undesired impurities. motor driven pump supplies feed stream to unit resulting in the creation of product and concentrate brine stream. The inclusion holding tank may be optionally omitted by routing outlet directly tap via branched line. pressure sensor causes solenoid valve open when withdrawal is terminated, opening branch line leading back pump. then continues run, recirculating mixing where it blended with major part that being recycled make-up fresh create composite As run this recirculation mode, entering becomes gradually purer, once quality reaches desired level, placed shutdown mode. Because high on side membrane unit, little contamination purified occurs during shutdown.
