TORAY Reverse Osmosis spiral wound membrane elements have been produced since 1967, starting with cellulose acetate membrane elements. Today, the product line includes a full range of state-of-the-art cross-linked polyamide composite membranes manufactured under ISO-9001 certification. Following 4” and 8” membranes can be used in multiple membrane systems to treat municipal industrial water, process water, sea water or high salinity water as well as commercial applications.

Reverse Osmosis Membranes Remove up to 99% Of Total Dissolved Solids.
RO Membranes Remove Dissolved Impurities Such As Chloride, Lead, Chromate, Fluoride, Bacteria and Others.
