The rear activated carbon filter of reverse osmosis pure water machine

Further in-depth removal of odor, residual chlorine and bacteriostasis, preventing secondary pollution of purified water, making drinking water more hygienic and safer. Activated carbon filtration, according to the adsorption characteristics of activated carbon, activated carbon is mainly used for removing pollutants in water, decolorizing, filtering and purifying liquid and gas, and also for air purification and waste gas recovery (such as the recovery of gas benzene in the chemical industry) , the recovery and refining of precious metals (such as the absorption of gold). Activated carbon is mainly made of substances with high carbon content, such as wood, coal, nut shells, bones, petroleum residues, etc. With coconut shell as the most commonly used raw material, under the same conditions, the active quality and other characteristics of coconut shell activity are the best, because it has the largest specific surface. Activated carbon is a kind of multi-pore carbon compound, which has a very rich pore structure and good adsorption characteristics. Its adsorption is formed by physical and chemical adsorption, and its appearance is black in color. In addition to the main carbon, its composition also contains a small amount of hydrogen, nitrogen and oxygen, and its structure resembles a hexagon. Features, each gram of activated carbon has a specific surface equivalent to 1,000 square meters.
