The water purifier can completely remove harmful substances and minerals from the water, and the purified water is pure water. The pressure of water is not enough for its working pressure, so a booster pump is needed, which requires electricity and pressure. One of its major disadvantages is that there is a lot of waste water, and generally about 50% of the waste water should be filtered out. Its purification cost is high and water yield is low, so it can only be used to solve the drinking water problem.
Extended data:
Water purifiers can be divided into gradual tightening water purifiers and self-cleaning water purifiers according to pipeline design grades. The traditional water purifier is a gradually tightening water purifier. Its internal pipeline is designed as a loose filter element at the front and a tight filter element at the back. It consists of PP melt-blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. Usually, these five stages are connected end to end. Trapped and deposited in the filter element, it needs to be disassembled and cleaned manually regularly to ensure the normal operation of the machine.
