What water does the water filtered by the water purifier belong to?

The water filtered by the water purifier belongs to pure water, and the water from the household water purifier is pure water filtered by ultrafiltration membrane, which removes harmful substances such as sediment, rust, bacteria and organic matter, while retaining mineral trace elements beneficial to human body.

It has high-precision filtering technology. The five-stage filtration technology of household water purifier includes filter element (PPF), granular activated carbon (UDF), precision compressed activated carbon (CTO), reverse osmosis membrane or ultrafiltration membrane, and post activated carbon (T33).

The water purifier is not only suitable for areas with serious tap water pollution, but also can filter residual chlorine in conventional tap water and improve the taste of water.

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. The other is a more advanced self-cleaning water purifier. Two channels are designed in the machine, and a washing water channel is added. When the washing water as ordinary domestic water passes through the channel, it washes the filter element in the machine, especially the raw water side of the membrane filter element, thus realizing self-cleaning.

At the moment of opening and closing the washing faucet, the trapped dirt can be quickly discharged in time by using the water flowing from the head section and the tail section. The structure design is reasonable, which saves the trouble of manual disassembly and cleaning, avoids the secondary pollution of the mechanism itself and reduces energy consumption.

However, consumers should pay attention to identification. Self-cleaning water purifiers are different from automatic sewage purifiers, computer automatic flushing water purifiers and automatic backwashing water purifiers seen in the market. The former is self-cleaning, which means that all the filter elements in the machine have certain self-cleaning function; The latter only cleans one of the filter elements, not the whole machine.

Generally speaking, the self-cleaning water purifier is equivalent to installing a garbage disposal device on the pipeline, which can clean up the dirty things at any time without leaving them in the machine. The traditional non-self-cleaning water purifier is equivalent to putting several trash cans in the room, and the dirt is usually temporarily stored in the machine, so it is necessary to regularly discharge the sewage and often disassemble, clean and replace the filter element.
