RO pure water filtration treatment machine
Reverse osmosis (RO) is a kind of membrane separation process driven by pressure gradient. It can effectively remove dissolved salt colloids and organic matters in water like molecular filter. The reverse osmosis process is the reverse process of natural osmosis. In order to produce reverse osmosis process, it is necessary to use water pump to exert pressure on saline solution to overcome its natural osmotic pressure, so as to make water pass through the reverse osmosis membrane; At the same time, in orderto prevent salt impurities in raw water from focusing on the membrane surface, concentrated water should continuously wash the membrane surface during operation, and take the impurities from the concentrated water and membrane surface to realize the whole process of reverse osmosis desalination and purification.
