China brand reverse osmoses membrane /ro membrane 4040

The membrane element applies to surface water, groundwater whose salt content is under 2000 parts per million, and some low pollution water after desalination processing. It also applies to replace the old system, secondary depth advanced treatment and water desalination from water with low salinity, etc. It is currently widely applied in municipal landscape and agricultural irrigation, drinking water of municipal water supply and drainage, water treatment, hospital/medical industry boiler make-up water, pure water, food processing and pharmaceutical manufacturing industry, laboratory pure water equipment, and other fields.The membrane element applies to surface water, groundwater whose salt content is under 2000 parts per million, and some low pollution water after desalination processing.

industrial RO membrane element LE series has low energy consumption, including 8-inch membrane elements and 4 inches membrane element which is divided into high desalination, high flux series. LE type series membrane element can effectively reduce the system pressure, save energy consumption and reduce running cost on the basis of ensuring water rate and desalting rate.
