Keensen RO Membrane Element RO-2012-100 50/75/100/200/300/400 for Water Purifier Company Information KeenSen Technology Co., Ltd.,was established in March, 2008, is a high tech company, specializing in professional separation membrane production and applications with its head office located in the High-tech Industrial Development District in Changsha, China. KeenSen RO membranes can be widely used in more than 50 industries, including water treatment projects , environmental restoration project etc. Product Description Reverse osmosis (RO) is a water purification technology that uses a semipermeable membrane to remove larger particles from drinking water. This membrane technology is not considered a proper filtration method. In reverse osmosis, an applied pressure is used to overcome osmotic pressure, a colligative property, that is driven by chemical potential, a thermodynamic parameter. Reverse osmosis can remove many types of molecules and ions from solutions, including bacteria, and is used in both industrial processes and the production of potable water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be "selective", this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely. KeenSen RO-1812-75 membranes are mainly applicable to small sized RO system with high rejection, such as home water purifier .
