Backwashing pre-filtration method of reverse osmosis pure water machine

Principle: The backwash pre-filter belongs to the "internal pressure type" under normal working conditions. Through the pressure of tap water, the inner wall of the filter screen penetrates into the outer wall, and particulate impurities such as sediment and rust are trapped in the pipe. The impurities trapped by the filter are washed away by the water. If the water quality is poor and the consumer does not wash it for a long time, there is no need to worry if it is blocked. Through the backwash switch, the piston is moved to the lower part, and the direction of the water flow is changed to "external pressure type".

Compared with the previous products, the backwashing pre-filter has been greatly improved in technology. The structure is reasonable and the water inlet and outlet can be rotated freely. It is easy to install, and the front body of the water pipe installation in any direction can be kept vertical; Reasonable "forward flushing and recoil flushing as you want" to completely flush out impurities and prevent secondary pollution caused by accumulation of impurities. The most critical point is that the accuracy can be as low as 5 microns, which is also different from other pre-filters. have.
