The role of Reverse osmosis water treatment

- Feb 03, 2020-

Reverse osmosis is a membrane separation technology with the highest filtration accuracy. The filtration accuracy is as high as 0.0001um, and it filters all water contained in tap water that does not contain minerals or trace elements. Water impurities such as dissolved solids, organics, colloids, and bacteria are protected by reverse osmosis membranes, concentrated into solution, and blocked and removed. Primary absorption removes more than 97% of dissolved solids

Reverse osmosis membranes work by separating pure water from dissolved solutions with a semipermeable membrane that allows only water to pass through. At this point, the pure water bank water will naturally pass through the semi-permeable lining and enter the solution field. When the liquid level reaches a certain level, the pressure of the membrane on both sides reaches the equilibrium point and the liquid level in the solution does not rise. At this point, there is a difference in pressure on both sides of the membrane, called the osmotic pressure. When a pressure higher than the osmotic pressure is applied to the solution side, the water molecules in the solution are throttled to the pure water side. This process is the reverse of absorption, called reverse osmosis, and can be seen from the reverse osmosis process because the molecular pressure of water in solution enters purified water. The solution to the problem is that the principle of intense reverse osmosis is to reverse the osmosis using greater pressure than natural osmosis, pushing water molecules from the raw water to the other side of the membrane. Putting salt into cell cladding water to achieve the goal This is the principle of separating salt from water, which is a reverse osmosis membrane.
