Working principle: Ro reverse osmosis is relying on the reverse osmosis membrane under enough pressure, make solution by reverse osmosis membrane solvents in pure water, so as to achieve the goal of removing salt. The pore size of ro reverse osmosis membrane is only nanoscale. Under a certain pressure, h2o molecules can go through the ro membrane, while the inorganic salts, heavy metal ions, organic matter, colloid, bacteria, viruses, and other impurities in the raw water can not pass ro membrane. Thus pure water and reject water are separated. -
