BMBW4040-ULP equivalent LG BW 4040 UES

ULP (Ultra low pressure) series of aromatic polyamide compound membrane element developed by  Besta Membrane .It can replace、 equivalent LG BW 4040 UES, FilmTec™ ULP 4040,Toray TMG10D etc.has the properties of low-pressure operation, high permeate flow and excellent desalination and is applicable to desalination of brackish water. Besides, it is particularly applicable to fabrication of high-purity water for electronic industry and electric power industry owing to its excellent performance in removing soluble salts, TOC, SiO2, etc.

Being suitable for desalting such water sources as surface water (NaCl ≤2000ppm), underground water, tap water and municipal water, etc., ULP series is mainly applicable to treatment of various industrial water such as industrial-purpose pure water, boiler water replenishment in power plants, and can be also applied to such brackish water applications, such as treatment of high-concentration saline waste water and production of beverage-purpose water.
