Adsorption Principle of Activated Carbon for Water Purification

Activated carbon for water purification is generally columnar particles with large specific surface area, developed micropores, high mechanical strength, fast adsorption speed, high purification degree, not easy to de-powder, and long service life. Activated carbon for water purification can be widely used in chemical, electronic, pharmaceutical, printing and dyeing, food and domestic water, industrial water, solution filtration, adsorption purification, impurity removal, and can also be used for deep purification of industrial wastewater. It can effectively remove odor, chlorine, cyanide and various heavy metal ions and other harmful substances and decolorize.

Adsorption Principle:

The use of activated carbon filter material adsorption method to purify water is to use its porous solid surface to adsorb and remove organic matter or toxic substances in the water to purify the water. Studies have shown that activated carbon has a strong adsorption capacity for organic matter with a molecular weight range of 500-1000. The adsorption of activated carbon on organic matter is affected by its pore size distribution and the characteristics of organic matter, mainly by the polarity and molecular size of organic matter. For organic matter of the same size, the greater the solubility and the stronger the hydrophilicity, the worse the adsorption of activated carbon on it. On the contrary, it has a strong adsorption capacity for organic matter with low solubility, poor hydrophilicity and weak polarity, such as benzene compounds and phenolic compounds. Activated carbon for water purification is generally used for water purification, removal of odor, removal of heavy metals and bacteria in water, and improvement of water quality. It is an ideal material for tap water, purified water, and high-purity water treatment. It can also be used for deep purification of sewage.

The activated carbon for water purification series is mostly made of coconut shells as raw materials and refined and processed using advanced production processes. The products have the advantages of developed pore structure, high strength, low impurity content, appropriate particle size, low resistance, and easy regeneration. It has an excellent effect on water purification. It can not only remove odor and improve the purity of water. It also has a high removal rate for various impurities in water such as chlorine, phenol, arsenic, lead, cyanide, pesticides and other harmful substances. It can be widely used to fill various large, medium and small water purifiers.
