Reverse osmosis is a membrane separation method which uses the pressure difference as the driving force to separate the solvent from the solution. The pressure is applied to the solvent on one side of the membrane, and when the pressure exceeds its osmotic pressure, the solvent will reverse permeate in the direction of natural infiltration. Therefore the permeating solution is obtained on the low-pressure side of the membrane, and the concentrated solution is obtained on the high-pressure side. The reverse permeable membrane can intercept all kinds of inorganic ions, colloidal substances, and macromolecular solutes in water with a simple process, low energy consumption, and it has been developed rapidly. Now it has been widely used in drinking water purification, seawater, brackish water desalination, and combined with ion exchange to produce high purity water.
The RO membrane is made of the semi-permeable membrane with the 0.0001um filtration rating for filtering and removing the metal irons, viruses, harmful dissolved solids, organics, bacteria, etc.
According to different water capacity New Filtration provide diverse sizes RO membrane，50GPD, 75GPD, 80GPD, 100GPD, 125GPD,200GPD, 300GPD, 400GPD and type range from High Flux, Low Pressure and Standard
Meanwhile, we also have other famous brands for an option such as the FILMTEC, CSM, FCS, VONTRON.
