The Filtration Method Of CTO Activated Carbon Filter Machine
Activated carbon filtration, according to the adsorption characteristics of activated carbon, activated carbon is mainly used to remove contaminants in water, decolorization, filtration and purification of liquids, gases, but also for the purification of air treatment, waste gas recovery (such as in the chemical industry, the recovery of benzene gas), precious metals recovery and refinement (such as the absorption of gold). The active carbon is mainly made of material with high carbon content, such as wood, coal, nutshell, bone, oil residue and so on.
Coconut shell is the most commonly used raw materials, under the same conditions, the active quality of coconut shell and other characteristics of the special is the best, because it has the largest surface. Activated carbon is a kind of porous carbonization, has very rich pore structure, has good adsorption properties, its adsorption by physical and chemical absorption of adsorption force, the appearance of color is black. In addition to the main carbon, also contains a small amount of hydrogen, nitrogen, oxygen, its structure looks like a hexagonal, due to irregular hexagonal structure, determined its many also the characteristics of the body of the orange and high surface area, each gram of activated charcoal with a surface of more than 1000 square meters.
