Shell shell activated carbon to high-quality raw materials, the use of physical methods by carbonization gas activation from. Has developed pore structure and reduce chroma, is filled with family, ideal material for water production equipment of social organizations, hotels and high purity purification. Shell activated carbon shell activated carbon price Iodine shell activated carbon activated carbon shell parameters! Shell activated carbon shells as raw material is high quality fruit, dried, refined processing and high temperature steam activation after charring from the high adsorption performance of activated carbon. Appearance is black amorphous particles, developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, low bed resistance, chemical stability, and easy regeneration, durability and other advantages, and has a variety of particle . Ningxia | DINGFENG shell activated carbon supply purposes: Ningxia | DINGFENG shell activated carbon is widely used in the supply of drinking water, industrial water and waste water depth purification; separation of various gases, purification, purification; organic solvent recovery; industrial sugar , MSG, medicine, liquor, beverages bleaching, deodorizing, refining; precious metal refining; chemical industry catalysts and catalyst supports. Ningxia | Supply DINGFENG shell activated carbon activated carbon treatment of wastewater containing chromium. Chromium is a larger amount of plating a metal material, hexavalent chromium in wastewater with different pH values, respectively, 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). Surface there is a lot 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), wastewater after adsorption can meet the national emission standards. Tests showed: solutions Cr (Ⅵ) concentration of 50mgL, 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 activated carbon treatment process of wastewater containing chromium are the result of the combined effect of activated charcoal solution Cr (Ⅵ) physical adsorption, chemical adsorption, chemical reduction and so on. Activated carbon treatment of wastewater containing chromium, adsorption stable performance, high efficiency, low operating costs, there is a certain social and economic benefits.
