Does anyone know why the water purifier uses the pre filter system?
2, the water purifier "pre filtration system" function is: effectively remove water rust, sand, colloid, and adsorption of water, chlorine, smell, color, pesticides and other chemicals. Pre filter: usually installed in the water after the water inlet pipe, is the first whole house water rough filtration equipment, can sediment, rust, large particles filtered tap water, can also protect the stable water pressure, water purification equipment connected in the back.Therefore, the water purifier is very necessary to use the pre filter system.Tips: popularize the basic knowledge of water purifier;1, water purifier, also known as water purifier, water filter, according to the use of water requirements for water depth filtration, purification treatment of water treatment equipment. The water purifier is usually used as a small filter for household use. The core of the technology is the filter film in the filter core device, and the main technology comes from two kinds of ultrafiltration membrane and RO reverse osmosis membrane. The types of water purifier are: ultra filter, pure water machine and pipe machine.
Third level: ultrafiltration membrane: ultrafiltration membrane can remove bacteria, viruses and spores in water.Level fourth: filter life indicator: the device for internal gear structure design, with the flow through a rotating gear, the axial internal movement, until the outlet is blocked, water cannot flow through, that is through the design of a good trip to calculate the total of the water purifier water, so as to ensure the water is safe. The composition of the water purifier is as follows:
Stage 1: micro filtration membrane: removal of various visible matter / dust and impurities in tap water by microfiltration. These particulate matter comes from pipe aging, rusting, roof water tanks, two pollution, and so on.Grade second: compressed carbon: compressed carbon to remove chlorine and organic impurities, such as harmful pesticides. It also absorbs odors, colors, and odors produced by organic compounds in water, which are derived from tap water disinfection by-products.
The water purifier is very necessary to use the pre filtration system, which is determined by its working principle and function;1, first of all, to see how the water purifier works, the general water purifier is composed of four stages of filtration system:
