Reverse osmosis is the most advanded and effective desalting technology. The principle is that under the higher pressure more than the dissolved solution osmotic pressure. Only follow water molecules through the reverse osmosis membrane. Then the solute and solvent separated,thereby getting the purified water. The fine particles,colloid, organic matter, bacteria, virus and 99%the dissolved salt can be removed by the water quality stability etc. already widely used in electronic, electrical, pharmaceuticle,food and other fields.
