The reverse osmosis technology is an advanced and energy-saving effective pure water and salt separation technology. The principle is that under the action of pressure higher than the osmotic pressure of the solution, solute in the solution is separated from solvent by means of selective interception of a semipermeable membrane (reverse osmosis membrane) which only allows water to permeate and does not allow other substances to permeate. By utilizing the separation characteristic of the reverse osmosis membrane, the impurities such as dissolved salt, colloid, organic matters, bacteria, microorganisms and the like in the water can be effectively removed, so that the production and living water with very low salt content is obtained.
