What is the working principle of the water purifier? Smayne will help you do a simple analysis.
Working principle of water purifier:
The first stage: microfiltration membrane: microfiltration membrane removes all kinds of visible objects/dust and impurities from tap water. These particles come from pipeline aging, rust, secondary pollution of roof water tank and so on.
Second stage: compressed carbon: compressed carbon removes chlorine and organic impurities, such as harmful pesticides. It can also absorb the odor, color and smell produced by organic matter in water, which come from disinfection by-products of tap water.
The third stage: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses and spores from water.
Most water purifiers adopt a progressive structure based on the screen-blocking filtering principle, which is composed of multi-stage filter elements connected in series from end to end. The precision of filter elements is arranged in sequence from low to high, so that multi-stage filter elements can share the trapped dirt, reduce the number of filter element blockage, manual sewage discharge and disassembly and washing, and prolong the cycle of replacing filter elements.
There is also a new design idea, which is the self-cleaning structure based on the principle of mass distribution. Its design idea is no longer to provide as much space as possible to store and receive pollutants, but to separate a small part of clean water by the principle of quality separation, and at the same time let the raw water flow as usual, so as to take away pollutants in time with the water flow and achieve the purpose of running water without rot. In this way, pure water can be obtained without or easily depositing dirt in the machine, which avoids secondary pollution, greatly reduces the loss of filter elements, and has better water quality, safety, energy saving and low carbon.
This new principle of self-cleaning water purifier improves the disadvantages of traditional water purifiers, resulting in higher impurity concentration of raw water in the machine and eventually becoming sewage. Therefore, the self-cleaning water purifier has no concept of sewage and sewage purifier, and it is replaced by washing water. With the improvement of living standards, the popularity of water purifiers will become wider and wider, and new technology products will better meet people's needs.
