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
