RO Membranes are semipermeable membranes used in Reverse Osmosis systems to filter out dissolved solids, impurities, and contaminants from water. They play a crucial role in producing high-quality purified water for drinking, industrial applications, and wastewater treatment by allowing only water molecules to pass through while rejecting larger molecules and ions.

The LP (low pressure) series of aromatic polyamide compound membrane element developed by Vontron Technology Co., Ltd. has the properties of low-pressure operation, high permeate flow and excellent desalination and are 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, 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 plant, and can be also applied to such brackish water applications as treatment of high-concentrated saline wastewater and production of beverage-purpose water.
All our ro & nf membranes are made of filmtec membrane sheet, so they have the same quality as filmtec membrane, but they are much cheaper. We have many standard sizes membranes, such as tw30-1812-50, tw30-1812-75, tw30-2012-100 for home drinking water system; tw30-4021, bw30-4021, tw30le-4040, bw30le-4040, tw30xle-4040, bw30xle-4040, bw30-365, bw30-400 for industrial use. Sw30-4040, sw30-2540 for purifying sea water etc...At the same time, we can do some customized membrane, such as tw30-2012-150, tw30-2812-200, tw30-3012-300
