The low pressure membrane element (LP) of an aromatic polyamide composition has low pressure properties, high permeate flow and excellent desalination and is useful for desalting brackish water. In addition, it is particularly suitable for the production of high-purity water for electronics and power engineering due to its excellent characteristics in the removal of soluble salts, TOC, SiO2, etc. It is suitable for the desalination of water sources such as surface water (NaCl ≤ 10,000 ppm), water and communal water, etc., the LP series can be used mainly for the purification of various industrial waters, such as clean water for industrial purposes, water for refueling boilers in power plants, and can also be used for brackish water rows, such as salt concentration and water production for the beverage industry.
