XLP membranes are suitable for desalination of surface water with low soil content (NaCl ≤1000ppm), groundwater, tap water and municipal water.
XLP membrane elements are particularly used for the second stage of demineralization in double-pass reverse osmosis systems. Mainly used for the production of clean water, boiler water, food and pharmaceutical water.
