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 naturalosmosis. 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 order
