The heart of any reverse osmosis system is the reverse osmosis (or RO) membrane.
US Water offers a full line of residential and commercial reverse osmosis membranes manufactured by or compatible with AXEON, DeSal, Dow Filmtec, GE, Toray, Hydranautics, R.O. UltraTec and others. We specialize in RO membranes which are 1.8 inch, 2.5 inches, and 4 inches in diameter, both residential and commercial reverse osmosis membranes.
We also offer different membranes for sea water applications, brackish water applications and many specialized high flow commercial and industrial applications.
Traditionally, reverse osmosis membranes have been of the CA (Cellulose Acetate), CTA (Cellulose Tri-Acetate) or TFC (Thin Film Composite). At US Water, we only carry the TFC membranes as CTA and CA are practically obsolete.
