RO membrane XLP11-4040
XLP series of extra-low pressure aromatic polyamide compound RO membranes can work under extra-low pressure to reach the same permeate flow as of regular low-pressure membrane elements and achieving rejection of up to 99.0%. XLP series can be effectively used for desalination of low salinity (NaCl ≤1000ppm) surface water, underground water, tap water, and municipal water.
XLP series of membrane elements is particularly applicable to the second-pass desalination with two-pass RO system and is mainly applied to pure water production, boiler water replenishment, foodstuff processing, and pharmaceutical production.
