Generalities
In a simple way, reverse osmosis systems can be described as an advanced filtration method with the use of semi permeable membranes for removal of dissolved ions and many types of molecules in water by applying external high pressure .
The applied pressure is used to overcome osmotic pressure, a natural property driven by concentration of dissolved material in liquids and the result is that the solute is retained on the pressurized side of the membranes and the pure solvent is allowed to pass to the other side.
Our BWRO systems are manufactured to produce purified water from raw water sources with salinity ranging from 500 ppm to 15.000 ppm. Standard models feature all components mounted on skid controlled automatically by a PLC connected to a user friendly HMI consisting of a touch screen monitor ( for industrial models ). Operational pressure generally stays under 20 bar. In most cases, systems are preceded by a proper pre-treatment to avoid membrane fouling by sediments, hardness, organic matter, bacteria, silica, metal oxides or even chlorine.
