Toray is discontinuing the production of some of their reverse osmosis (RO) membranes. These membranes are being replaced in Sterlitech's line-up by the new 70HA, 70AC, 72U, and 82V membranes will be overtaking some of Toray's newly obsolescent membranes. The table below lists the specifications of the new and obsolete membranes for easy comparison. To browse our complete selection of RO membranes or to place an order with us, click here.
