Reverse osmosis equipment filtering mainly in the following steps:
Yi class filter: 5 micron PP fiber filter, play a preventive treatment.
The second level of filtration: granular activated carbon filter, the same is expected to deal with.
The third level of filtration: high-density sintered activated carbon filter, further filtering treatment.
The fourth level of filtration: also four-core RO membrane reverse osmosis technology. Is under the action of pressure, the water through the reverse osmosis membrane into pure water; water impurities are trapped by reverse osmosis membrane and was concentrated with water. The use of reverse osmosis technology can effectively remove inorganic salts in water, colloid, fine jun, virus, fine jun endotoxin and most organic matter;
The fifth level of filtration: a post-antibacterial activated carbon, known secondary pollution.
Characteristics of Membrane Separation Technology in Reverse Osmosis Water Treatment Equipment
(1) membrane separation technology for thermal sensitive material separation effect is good. Because the membrane separation technology is carried out at room temperature.
(2) membrane separation technology for a wide range, and the reaction process will not change the material properties, do not need to participate in the reaction of additives, will not bring new pollutants and waste of other substances can be used for many types of wastewater Processing process.
(3) membrane separation technology required equipment is simple, easy to repair, and equipment covers an area of less than the conventional treatment methods, the treatment effect is good, so the operating costs are low.
(4) membrane separation technology equipment can be customized, self-control strong, easy to manage and run, but also conducive to industrial development.
(5) to reduce the sewage treatment residue, ion water reverse osmosis equipment, improve the surface water re-use rate.
(6) irrigation of the most rational use of water.
