RO membrane ULP22-8040
ULP series of ultra-low pressure aromatic polyamide compound RO membranes can work under ultra-low pressure to reach the same permeate flow and rejection as of regular low-pressure membrane elements. ULP series can be effectively used for desalination of surface water (NaCl ≤2000ppm), underground water, tap water, and municipal water.
ULP membrane elements are mainly used for boiler water replenishment, foodstuff processing, and pharmaceutical production.
Effective operation at a lower pressure can decrease the investment costs for related equipment such as pumps, pipelines, and containers, etc. and the operating cost for the RO system, thus increasing the economic efficiency.
