Filtration Method Of Activated Carbon Filter Element

Activated carbon filtration, according to the adsorption characteristics of activated carbon, activated carbon is mainly used to remove pollutants in water, decolorize, filter and purify liquids and gases. It is also used for air purification and waste gas recovery (such as the recovery of gas benzene in the chemical industry) , Recycling and refining of precious metals (such as the absorption of gold). Activated carbon is mainly made of materials with high carbon content, such as wood, coal, fruit shells, bones, and petroleum residues. With coconut shell as the most commonly used raw material, under the same conditions, the active quality and special characteristics of coconut shell activity are the best, because it has the largest specific surface area. Activated carbon is a kind of carbon with multiple pores. It has a very rich pore structure and good adsorption characteristics. Its adsorption is formed by physical and chemical absorption, 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. Its structure looks like a hexagon. Due to the irregular hexagon structure, it is determined that it is mostly solid and has a high surface area. Characteristic, every gram of activated carbon has a specific surface equivalent to 1000 square meters.
