XLP aromatic poly-amide composite elements is specially developed for higher permeate flux. Delivers high quality water at extreme low operating conditions,operating pressure is about half of conventional brackish water membranes, which is able to reduce investment cost for membrane system pipelines, pumps & other equipment and system operation cost to improve the economic benefits.
It is mainly used for treatment of surface water, groundwater and municipal water salinity<1000mg/L.The application fields include purified water, bottled drinking water, and the second pass of a two-pass membranes system. It has the characteristics as low energy consumption, higher permeate flow, extreme low operating pressure as well as high rejection rate.
