Water purifiers, also called water purifiers and water purifiers, are water treatment equipment that perform deep filtration and purification of water according to the requirements for water use. Water purifiers usually refer to small purifiers used in households.
The core of its technology is the filter membrane in the filter element device. The main technology comes from three types: ultrafiltration membrane, RO reverse osmosis membrane, and nanofiltration membrane. The role is to purify harmful substances in water and impurities in the water. Originated in the early 1880. Originated in London, England. Water purification technology. Ceramic filtration.

Water purifiers can be divided into two categories according to pipeline design grades: progressively tightening water purifiers and self-cleaning water purifiers. The traditional water purifier is a gradually tightening water purifier. Its internal pipeline is designed with a filter element that is loose before and then tightened. It is composed of PP melt blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and activated carbon at the rear. It is composed of these 5 levels in turn end to end. The retentate is deposited inside the filter element and needs to be manually disassembled and washed 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 used as ordinary domestic water passes through the channel, it affects the filter element in the machine, especially the raw water of the membrane filter element. The side plays the role of flushing to achieve self-cleaning, and uses the water that flows away from the head and tail at the moment of opening and closing the washing faucet to discharge the trapped dirt in time and quickly. This structure is designed reasonably and saves labor. The trouble of dismantling and washing avoids re-pollution of the organization itself and at the same time reduces energy consumption costs.
But consumers are reminded to recognize that self-cleaning water purifiers are different from the automatic sewage water purifiers, computer automatic flushing water purifiers and automatic backwashing water purifiers seen on the market. The former is self-cleaning, that is, It is said that all filter elements inside the machine have a certain self-cleaning function; the latter only washes one of the filter elements instead of the whole machine. In layman’s terms, the self-cleaning water purifier is equivalent to a garbage disposer installed in the pipeline, and the dirt is cleaned out at any time without staying in the machine. The traditional non-self-cleaning water purifier is equivalent to putting multiple trash cans in the room, and the dirt is usually temporarily stored in the machine, so it needs to be drained, removed and washed regularly, and the filter element needs to be replaced frequently.
The function of the water purifier is to remove floating substances, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. in the water. It has high-precision filtration technology, and the five-stage filtration technology of household water purifiers The first level is the filter element, also known as PP cotton filter element (PPF), the second level is granular activated carbon (UDF) filter element, the third level is precision compressed activated carbon (CTO) filter element, and the fourth level is reverse osmosis membrane or ultrafiltration membrane. The fifth level is the post activated carbon (small T33). The water purifier is not only suitable for areas with serious tap water pollution, but also can filter the residual chlorine in conventional tap water, and at the same time can improve the taste of water.
The first level: PP cotton: remove all kinds of visible objects/dust and impurities in tap water.
The second and third stage: pre-activated carbon: part of the third stage of low-profile water purifier is also PP cotton, carbon to remove chlorine and organic impurities. It can also absorb the peculiar smell, color and smell produced by organic compounds in the water.
The fourth level: ultrafiltration or reverse osmosis membrane: the membrane can remove bacteria, viruses, spores and other substances in the water.
The fifth level: post activated carbon device: to further improve the taste and remove peculiar smell.
Most of the water purifiers adopt a progressive structure method based on the principle of screen-blocking filtration, which is composed of multi-stage filter elements connected in series, and the filter elements are arranged in order from low to high precision to realize multi-stage filter elements to share and intercept the dirt, thereby reducing filter element clogging And the number of manual drainage, disassembly and washing, and extension of the replacement cycle of the filter element. There is also a new design idea that applies the principle of quality distribution and self-cleaning structure. Its design idea is no longer to provide as much space as possible for collecting dirt, but to adopt the principle of quality separation to separate a small amount of dirt. Part of the clean water, and at the same time, let the raw water circulate as much as possible so that the pollutants can be taken away with the water in time, so that the water does not rot. In this way, purified water is obtained, and it will not or be difficult to deposit dirt in the machine, avoid secondary pollution and greatly reduce filter element loss, and the water quality is better, safer, and energy-saving and low-carbon. This new principle self-cleaning water purifier won the Gold Award at the 7th International Exhibition of Inventions. It has a one-in-two-out structure. It improves the impurity concentration of the raw water in the machine due to the structural defects of one in and one out of the traditional water purifier. The more it accumulates, the higher it eventually becomes sewage. Therefore, the concept of self-cleaning water purifiers without sewage and sewage water purifiers 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 are better meeting people’s needs.
