Shell activated carbon to high-quality fruit shell as raw material, the use of physical methods by carbonization gas activation from. Has developed pore structure and reduce chroma, is filling the family, the ideal material for water production equipment social groups, hotels and high-purity purification. Shell activated carbon | husk carbon price | shell activated carbon Iodine value | shell activated carbon parameters! Shell activated carbon is high-quality fruit shell as raw material, dried, after charring and high temperature steam activation refined processing of high adsorption properties of activated carbon. Look for black amorphous particles, developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, bed resistance, good chemical stability, easy regeneration, durability, etc., and have a variety of particle size . Shell activated carbon use: shell activated carbon is widely used in deep purification drinking water, industrial water and wastewater; various gas separation, purification, purification; organic solvent recovery; industrial sugar, monosodium glutamate, medicine, liquor, beverages refining of precious metals;; decolorization, deodorization, refining chemical industry catalyst and catalyst carrier. Shell activated carbon activated carbon treatment of wastewater containing chromium. Chrome plating in a larger amount of a metal material, hexavalent chromium in the waste water with pH values ??were different in different forms. Activated carbon has a very well-developed porous structure and high specific surface area, with a strong physical adsorption capacity, can effectively absorb wastewater Cr (Ⅵ). The presence of a large number of the surface of activated carbon-containing groups such as hydroxyl (-OH ), carboxyl (-COOH), etc., they have electrostatic adsorption function of Cr (Ⅵ) chemical adsorption. Can be used in electroplating wastewater Cr (Ⅵ), water adsorption can meet the national emission standards. Tests showed that: the solution Cr (Ⅵ) concentration of 50mg / L, pH = 3, when the adsorption time 1.5h, adsorption properties of activated carbon and Cr (Ⅵ) removal are the best results. Therefore, the use of chromium-containing wastewater treatment process of activated carbon is the result of the combined effect of activated carbon in solution Cr (Ⅵ) physical adsorption, chemisorption, chemical reduction, etc.. Activated carbon treatment of wastewater containing chromium, adsorption stable performance, high efficiency, low operating costs, there is a certain social and economic benefits.
