ULP (Ultra Low Pressure) series membrane
1,ULP series membrane elements are applicable to desalination of surface water,groundwater,tap water and the municipal water etc source of water whose saltness is about less than 2000ppm. It can mainly applied to many kinds of fields as follows :all kinds of pure water, boiler feed water, food processing and pharmaceutical manufacturing industries etc.
2,The operating pressure is about two thirds of conventional low pressure composite membrane,and the desalination rate is the 99.5%. Thereby reducing the associated pumps, piping, containers and other equipment investment costs and running costs of reverse osmosis systems, improving the economic efficiency.
