Water purifier, also known as water purifier, water purification machine, is a water treatment equipment that deeply filters and purifies water quality according to the requirements of water use. The water purifier usually refers to a small purifier used as a home. Its technical core is the filter membrane in the filter element device, and the main technology comes from ultrafiltration membrane, RO reverse osmosis membrane and nanofiltration membrane.
The function of the water purifier is to filter the floating matter in the water, heavy metals, bacteria, viruses, residual chlorine, sediment, rust, microorganisms, etc. are removed, it has a high precision filtration technology, the first stage of the five-stage filtration technology of the water purifier used in the home is also known as the PP cotton filter element (PPF), the second stage of the particle activated carbon (UDF) filter, the third stage is the precision compressed activated carbon (CTO) filter, the fourth stage is the reverse osmosis membrane or ultrafiltration membrane, and the fifth stage is the post-activated carbon (small T33). Water purifiers are not only suitable for areas with serious tap water pollution, but also filter the residual chlorine in conventional tap water, and at the same time improve the taste of water. In August 2013, the General Office of the National Health and Family Planning Commission issued the "Specification for the Management of Labeling Instructions for Products Involving Drinking Water Sanitation and Safety", which clearly states that the labels and instructions of water-related products shall not be marked with "acidic water", "alkaline water", "activated water", "small molecular group water", "functional water", "energy water", "oxygen-rich water" and other contents.
How it works Grade 1: PP cotton: Removes all kinds of visible substances/dust and impurities from tap water. The second and third grades: pre-activated carbon: the third stage of some low-grade water purifiers is also PP cotton, and the carbon removes chlorine and organic impurities. It also absorbs odors, colors and odors produced by organic compounds in water. Fourth stage: ultrafiltration or reverse osmosis membrane: the membrane can remove bacteria, viruses and spores and other substances in the water. Stage 5: Rear activated carbon device: further improve the taste and remove odor.
