        Why choose RO reverse osmosis purifier

        Reverse Osmosis (RO) : When dilute solution (such as fresh water) and concentrated solution (such as brine) of the same volume are placed on both sides of the semi-permeable membrane, the solvent in dilute solution will naturally pass through the semi-permeable membrane and flow spontaneously to the side of the concentrated solution. This phenomenon is called Osmosis.If a pressure greater than osmotic pressure is applied on the side of the concentrated solution, the flow direction of the solvent will be opposite to the original osmotic direction and begin to flow from the concentrated solution to the side of the dilute solution, this process is called reverse osmosis.Reverse osmosis is a kind of reverse migration movement of osmosis. It is a pure physical separation method that separates solute and solvent in solution by selective interception of semi-permeable membrane under pressure drive.


        The application of reverse osmosis technology: it was first used by American astronauts to recycle urine into pure water.Reverse osmosis is also used in the medical community for kidney washing (hemodialysis).Reverse osmosis membrane can completely separate heavy metals, pesticides, bacteria, viruses, impurities and so on.The whole working principle adopts the physical method, does not add any fungicide and chemical substances, so will not produce chemical transformation.It has been widely used in the purification and concentration of various liquids, among which the most common application example is in the water treatment process, the use of reverse osmosis technology to remove inorganic ions, bacteria, viruses, organic matter and colloid and other impurities in the raw water, in order to obtain high quality pure water.Reverse osmosis membranes do not separate the dissolved oxygen, so the pure water produced by this method is living water and tastes sweet and fresh.RO reverse osmosis technology is widely used in bottled water, bottled water and beverage.
