Your
Reverse osmosis is the separation of one component of a solution from another component by means of pressures exerted on a semipermeable membrane element. Removal of ionic, organ- ic and suspended / dissolved impurities occurs during the RO process. Unlike a filter, which separates by “normal” filtration, the General Electric (GE) Osmonics membrane element sep- arates using a process called cross flow filtration. Feed water solution is separated into two streams, permeate and concentrate, and collected from both sides of the membrane element. A semipermeable RO membrane element, under sufficient pressure, allows passage of purified water while rejecting and concentrating dissolved and suspended solids.
