RO Membranes - Reverse Osmosis Systems Print E-mail

RO Membranes - A reverse osmosis membrane is a semipermeable material, i.e. a material through which water passes relatively quickly, while other substances cannot (or do so relatively slowly). Membranes provide the barrier layer or interface for cross flow separation. RO membranes are made from a thin, porous material constructed of organic polymer (e.g. cellulose acetate, polyamide and charged polysulfone).

Reverse osmosis membranes will typically reject contaminants with molecular weights greater than 200. Ultrafiltration membranes will reject contaminants with molecular weights between 10,000 and 0.1 micron.
