Description
Vontron reverse osmosis membrane LP21-4040 is primarily used in desalination of brackish water. This series features low operating pressure, high permeate flow and rejection. It has high performance in rejecting soluble salt, TOC and SiO2, and can be widely applied in pure water production in electricity and electronic industries. Drinking water production, such as: packaged water, direct drinking water, food processing water, etc. Purified water production, such as: pharmaceutical water, medical water, electronics water, etc.
