Filtration methods and characteristics of activated carbon filter equipment

- Feb 27, 2020-

Activated carbon filtration. According to the adsorption characteristics of activated carbon, activated carbon is mainly used to remove pollutants in the water, decolorize, filter and purify liquids and gases, and also used for air purification treatment and exhaust gas recovery (such as the recovery of gaseous benzene in the chemical industry). Recycling 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. Coconut shell is 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.

Activated carbon is a kind of multi-pored carbide with extremely rich pore structure and good adsorption characteristics. Its adsorption is made by physical and chemical suction, and its appearance is black. In addition to the main carbon, its composition also contains a small amount of hydrogen, nitrogen, and oxygen, and its structure looks like a hexagon. Due to the irregular hexagonal structure, it is determined that it has a large volume and high surface area. Characteristics: Each gram of activated carbon has a specific surface equivalent to 1,000 square meters.

Activated carbon filter is a true deep structure with dual functions of filtration and purification. The precision of the filter is 10 micron nominal filtration accuracy. There is no need to add filter aid when using, nor need to filter after carbon treatment. Each activated carbon filter element contains 160 grams of plant sulfur-free activated carbon particles. Used for electroplating bath purification, because the filter element does not precipitate fibers or other substances, which causes pinholes or brittleness in the plating layer. The activated carbon filter mainly depends on the quality of the activated carbon he uses.

Using natural high-quality coconut shell as raw material, refined by physical activation method, non-toxic, odorless, well-developed pores, free of dissolved substances in water that have adverse effects on water quality, strong adsorption capacity, fast filtration speed, and effective adsorption of excess water Chlorine and peculiar smell make deep purification to remove industrial waste water, COD, pigment, ozone and other harmful substances in sewage, river water quality, electronics industry, pharmaceutical industry, preparation of ultrapure water and purification of food industry water. According to the actual requirements of users, special indicators of activated carbon can be developed.
