Water purifier design by piping grades can be divided into getting tight and self-cleaning water filter water purifier two categories. Traditional water purifier is getting tight, also known as progressive water purifier, its internal piping design filter before and after the tight loose by the PP meltblown filter, granular activated carbon, compressed charcoal, RO reverse osmosis membrane or membrane, after activated carbon, this is generally composed of five successively end to end, the machine line only this one path, dirt is deposited on the filter inside, require regular manual washable to ensure the normal operation of the machine. The other is more advanced self-cleaning water filter, designed the machine two channels, added a wash water passages, wash water and water purification have a complete path, and let the water flow prevails both stand up. As usual ordinary domestic water wash water passes through the path of the machine especially membrane cartridge filter raw water side play scour the role in order to achieve self-cleaning and washing faucet with the momentary opening and closing paragraphs of that is already run off the head and tail Water trapped dirt will promptly and quickly discharged, this structure is designed to be reasonable, eliminating the trouble of manually washable, eliminating the institution itself again pollution, while also reducing energy costs. Shanxi Runtong Environmental Engineering Limited was founded in 2005, is a professional sewage treatment, waste gas treatment, dust handling and other types of environmental projects and research and design of high-tech enterprises. Here to tell you about water purifier filter functions: 1, polypropylene spray solvent filter (PPF) filter function: Removal of sediment, rust, water purification equipment, algae and other solid substances. 2, softening resin filter cartridge features: raw water softening filter adsorption of heavy metals and excess calcium and magnesium cations water purification equipment prices, softening hard water, anion exchange resin anion exchange only, not exchangeable cations, ion exchange resins can significantly reduce water hardness, reducing metal ion precipitation in the body, reducing the chance of human stones Shanxi pure water equipment, water purification equipment to solve the scale problem, Shanxi, and improve the taste of water, it can be regularly placed in 6-10% sodium chloride (chlorine potassium) solution that is regenerated using. 3, granular activated carbon filter (UDF) filter function: to remove chlorine, odor, and solid impurities 4, compressed activated carbon filter (CTO) filter function: further removal of chlorine, odor, and solid impurities.
