Ceramic plug core pure water machine adopts are mainly reverse osmosis membrane technology. Pure water machine work principle is to use enough pressure (high pressure pump here as a for the system to provide the stable high pressure and flow of the role of water) make the solution of the solvent (typically water) through the reverse osmosis membrane (or called semipermeable membrane) and isolated, because this process and natural penetration direction on the contrary, therefore is called reverse osmosis. After reverse osmosis treatment, make the content of impurity in water to reduce, to improve the purity of water quality, the desalination rate can reach more than 98%, and the water most of the bacteria, colloid and high molecular weight organic matter removal
