Introduction of working principle of household water purifier

With the increase of water purifier companies, the water purifier company introduces the working principle of home water purifier to us:

First stage: microfiltration membrane: microfiltration membrane can remove all kinds of visible substances / dust and impurities in tap water. These particles come from aging of pipes, rusting, secondary pollution of roof water tanks and so on.

Second stage: compressed carbon: compressed carbon removes chlorine and organic impurities, such as harmful pesticides. It can also absorb the peculiar smell, color and odor produced by organic compounds in water, which come from the disinfection by-product of tap water.

The third level: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses, spores and other substances in water.

The fourth stage: filter element life indicator: the internal part of the device is designed with gear structure. As the water flows through, the gear rotates to make an axial upward movement inside until the water outlet is blocked, and the water flow cannot pass through, that is to say, the designed stroke is used to calculate the total water flow of the water purifier, so as to ensure the safety of the water outlet.

Most of the water purifiers adopt the progressive structure mode of screen blocking filtration principle, which is made up of multi-stage filter elements connected in series from the head to the tail. The filter elements are arranged in order of precision from low to high, so as to realize the allocation of multi-stage filter elements to intercept pollutants, so as to reduce the number of filter element blockage and manual blowdown, removal and washing, and prolong the cycle of replacing filter elements. Another new design idea is to apply the principle of mass separation and circulation to self-cleaning structure. Its design idea is no longer to provide as much space as possible for dirt collection and scaling, but to adopt the principle of mass separation to separate a small part of clean water, and at the same time, to make the raw water flow as usual so that the sewage can be taken away in time with the water flow, so that the water does not rot. In this way, the purified water will not or is not easy to precipitate the dirt in the machine, avoid the formation of secondary pollution and greatly reduce the loss of filter element, and the water quality is better, safer, energy-saving and low carbon. This new principle of self-cleaning water purifier won the gold medal of the 7th International Invention Exhibition. It is a one in two out structure. It improves the traditional water purifier because of the structural defects of one in one out, resulting in the higher concentration of raw water impurities in the machine, and finally becomes sewage. Therefore, the concept of self-cleaning water purifier without sewage and sewage water purifier is replaced by washing water. With the improvement of living standard, the popularization of water purifier will be more and more extensive, and new technology products are better meeting people's needs.
