1、Reverse osmosis membrane technology
Reverse osmosis is also called RO reverse osmosis. The organic solvent in the aqueous solution is separated according to ro system membrane. Because it is opposite to the direction of normal penetration, it is called reverse osmosis. According to the different osmotic concentration of various raw materials, the reverse osmosis method greater than the osmotic pressure can be separated, obtained, purified and concentrated.
The reverse osmosis used in reverse osmosis membrane technology is a high 0×10-10 (10A) with a diameter of less than 10×10-10 (10A), which can remove the elemental type and organic matter with relatively small molecular weight in the leachate, such as bacteria , Virus infection, pyrogen, etc. Ro system membrane it has been widely used in the elimination of sea surface or brackish water, in the production and manufacture of electronic equipment, medicinal purified water, edible purified water, and outer space water, as well as in microorganisms and medical engineering.
Reverse osmosis membrane technology characteristic is that under the constant temperature standard, the concentration of the substance and the water can be separated or concentrated, so the energy consumption is low; the residue covers a wide area and can remove carbonate and various organic residues; the water recovery rate is high; the separation equipment is simple, The actual operation and maintenance are convenient.
2、Reverse osmosis element membrane application standards
Outer space water, mineral water, purified water, wine production, manufacturing and dewatering water; early water use in pharmaceuticals, electronic equipment and other fields; concentration, separation, purification and drainage of chemical processes; replenishing water, salt and softened water for heating furnaces; Elimination of sea surface and brackish water; water and sewage treatment in paper industry, electroplating process, printing and dyeing plant and other fields.
Reverse osmosis is a high-tech membrane separation technology under the development trend of the 1960s. It has a small diameter and can remove the elemental types and organic matter with small relative molecular mass in the leachate, such as bacteria and virus infections.
