Reverse Osmosis (RO) Pure Water Treatment
- Aug 07, 2018 -

      Reverse osmosis refers to that when a pressure greater than osmotic pressure is applied on the side of concentrated solution, the solvent in concentrated solution will flow to the dilute solution, this principle is used in liquid separation fields used in purification and removing impurity, processing working principle of the reverse osmosis membrane liquid substances: for substances through a selective membrane called the semi-permeable membrane, general will only through solvent rather than through the solute film called ideal semi-permeable membrane When the same volume of dilute solution (such as fresh water) and concentrated solution (such as salt water), respectively, on both sides of the membrane, dilute solution of the solvent nature through a semipermeable membrane and spontaneously to the concentrated solution on one side of the flow, this phenomenon is called the infiltration When osmotic balance, the concentrated solution on one side of the liquid level will be higher than the level of dilute solution a certain height, the formation of a differential pressure, the pressure difference is the osmotic pressure reverse osmosis is a reverse migration movement, is a pressure driven by withholding effect on the choice of a semipermeable membrane separation of the solute in the solvent is separated from solvent method, it has been widely used in all kinds of purification and concentration of solution, one of the most common application is in the water treatment process, the inorganic ions in raw water with reverse osmosis technology bacteria, virus and colloidal impurities such as organic matter removal, in order to obtain high quality of pure water
