Pollution-resistant brackish water reverse osmosis membrane working principle

When pure water and salt water are separated by an ideal semi-permeable membrane, the ideal semi-permeable membrane only allows water to pass through and prevents salt from passing through, at this time the water on the pure water side of the membrane will spontaneously flow into the salt water side through the semi-permeable membrane, this phenomenon is called osmosis, if pressure is applied to the salt water side of the membrane, then the spontaneous flow of water will be inhibited and slowed down, when the applied pressure reaches a certain value, the net flux of water through the membrane is equal to zero, this pressure is called osmosis pressure, when pressure is applied to the membrane, the net flow of water is equal to zero. Pressure, when the pressure exerted on the brine side of the membrane is greater than the osmotic pressure, the flow of water will be reversed, at this time, the brine in the water will flow into the purified water side, the above phenomenon is the reverse osmosis (RO) treatment of the basic principles of water.
