Factory direct reverse osmosis water purification equipment

Water purification equipment generally grouped into 3 categories: filtration, purification, softening. Filtration and purification equipment capacity can be used for drinking water, softened water equipment production is for domestic use. Water purification system refers to the selection of several of these devices, combined into a complete water treatment system. Reverse osmosis is 60 years developed a new membrane separation technology, is to rely on reverse osmosis membrane under pressure in the solution of solvent and solute separation process. To understand the principle of reverse osmosis desalination, first understand the "infiltration" concept. Penetration is a physical phenomenon, when two water containing different concentrations of salts, such as using a semi-permeable membrane to separate will find that the water salinity is less of a joint seep through the membrane salinity high water, and salt contains not penetrate, so that gradually the salt concentration of the two together to equal integration so far. However, to accomplish this process takes a very long, this process is also known as the natural infiltration. But if the high salt content of the water side, plus a stress test, the results can also be said infiltration is stopped, when the pressure is called osmotic pressure. If the pressure is again increased, so that the water can penetrate in the opposite direction, and the remaining salt. Therefore, the principle of reverse osmosis desalination, is in the salty water (such as raw water), to impose more pressure than the natural osmotic pressure, the permeate in the opposite direction, the water molecules in the raw water pressure to the other side of the membrane, into clean water, so as to achieve the purpose of removing the salt water, which is the principle of reverse osmosis desalination.
