Working principle

Reverse osmosis,short for RO, which is under external pressure, and some components in solution through selective, so as to realize the purpose of desalination, purification and enrichment separation. When it is used in water treatment equipment, it can remove most ions in water, and also the fine particles, bacteria and organic impurities. Nowadays, it is the advanced and economic water treatment equipment over the world. Reverse osmosis is used of high pressure pump continuously to force the water content high salt delivered to the RO device, RO device comprises a reverse osmosis membrane element and the pressure vessel, input water is divided into low salt of penetration solution and high salt of concentrated solution. Water is controlled by regulating valve according to proportion of the concentrated solution and penetration solution.
