BMBW8040-440-LP Equivalent CPA2
BMBW8040-440-LP model membrane element is a high-flux membrane developed and produced by Besta Membrane. This membrane element has an effective membrane area of 440 square inches, providing higher water flux and greater treatment capacity compared to the common 400 square inch membrane elements. It is an equivalent replacement for the Hydranautics CPA2-8040.
LP (low pressure) series of aromatic polyamide compound membrane element developed by BM 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 ≤10000ppm), underground water, tap water and municipal water, etc., LP 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.
