General Brackish Water ULP Series RO Membranes

IonClear™ ULP series RO membranes are suitable for desalination treatment of water sources such as surface water, ground water, tap water and municipal water with a salt content below about 2000ppm. They are mainly used in various scales of pure water, boiler feed water, food processing and pharmaceutical manufacturing industries, etc. In this field, it can achieve the same high flux and high rejection rate as conventional low-pressure membranes under ultra-low operating pressure conditions. Its operating pressure is about 2/3 of that conventional low-pressure composite membranes, and the rejection rate can reach 99.5%, thereby reducing the investment costs of related pumps, pipelines, containers and other equipment and the operating costs of reverse osmosis systems, and improving economic benefits.
