Activated carbon has a porous structure, which can adsorb suspended solids in water, and can also adsorb substances with different weight or color dissolved in water. It can remove some insoluble and soluble impurities in water.

What is activated carbon? It looks like a black sand. Activated carbon from ordinary coal is characterized by its activation process (which is subjected to high temperature and in the absence of air at all). As a result of this process, it will open the pores in the body, which is a special property of activated carbon.

Activated carbon depends on the degree of activation. The larger the specific surface area, the greater the adsorption capacity.

Activated carbon is a porous black material, which is obtained from carbonaceous materials, known as activated carbon.

The materials used in the manufacture of activated carbon can be various organic materials: coal coke, charcoal, petroleum coke, coal, coconut, and others.

Activated carbon is characterized by a very large specific surface area and a large number of pore structures in the activated carbon. It is because of the high adsorption of this activated carbon. The specific surface area per gram can be 500 to 2000 square meters. It can be used efficiently in various industries.

The work of activated carbon filter is completed by carbon bed. The activated carbon particles composed of carbon bed have many micropores and huge specific surface area, and have strong physical adsorption capacity.

When water passes through activated carbon bed, organic pollutants in water are effectively adsorbed by activated carbon. In addition, there are some oxygen-containing tube clusters on the amorphous part of the activated carbon surface, so that the organic pollutants in the water passing through the carbon bed can be effectively adsorbed by the activated carbon.

Activated carbon filter is a kind of common water treatment equipment. As the pretreatment of water treatment desalination system, it can effectively ensure the service life of the later stage equipment, improve the quality of effluent, and prevent pollution, especially the free residual oxygen poisoning pollution of the back stage reverse osmosis membrane and ion exchange resin.

Activated carbon filter is mainly used to remove organic matter, smell, color, heavy metal ions, residual chlorine (Cl2) and so on. As pretreatment of reverse osmosis, electrodialysis and ion exchanger. Granular activated carbon device about these equipment can play a good maintenance effect.

Application and types of activated carbon:

Air purification, sewage treatment plant exhaust adsorption, beverage water treatment, power plant water pretreatment, wastewater recovery pretreatment, biological wastewater treatment, toxic wastewater treatment, petrochemical alkali free mercaptan, solvent recovery, chemical catalyst carrier, filter tank, gold extraction, chemical storage exhaust purification, sugar making, alcohol, monosodium glutamate medicine, food refining, decolorization, ethylene desalting filling Materials, automobile exhaust purification, PTA oxidation device purification gas.
