Nutshell activated carbon is made of high-quality coconut shells, apricot shells, peach shells, walnut shells and other harder shells as raw materials, and is refined by advanced carbonization, activation, and superheated steam treatment. The appearance is black amorphous particles. wholesale activated carbon It has the advantages of developed pore structure, large specific surface area, strong adsorption capacity, high mechanical strength, low bed resistance, good chemical stability, easy regeneration, and durability.

Widely used in the deep purification of drinking water, industrial water and wastewater; separation, purification, and purification of various gases; organic solvent recovery; decolorization, deodorization, and refining of sugar, MSG, medicine, alcohol, and beverages; precious metal extraction ; Catalysts and catalyst carriers in the chemical industry.

In industrial production, cyanide or by-product cyanide is used in the wet extraction of gold and silver, chemical fiber production, coking, ammonia synthesis, electroplating, and gas production. Therefore, a certain amount of cyanide must be discharged during the production process. Wastewater.

Activated carbon has the performance of adsorbing mercury and mercury-containing compounds, but its adsorption capacity is limited, so it is only suitable for treating wastewater with low mercury content. If the concentration of mercury is high, it can be treated by chemical precipitation first. After treatment, the mercury content is about 1mg/L, and when it is high, it can reach 2-3mg/L, and then use activated carbon for further treatment.

Phenol-containing wastewater widely comes from petrochemical plants, resin plants, coking plants and oil refineries. dxdcarbon  Experiments have proved that the activated carbon has good adsorption performance for phenol, and the increase in temperature is not conducive to the adsorption, which reduces the adsorption capacity; but the time for increasing the temperature to reach the adsorption equilibrium is shortened.

There is an optimal value for the amount of activated carbon and adsorption time. Under acidic and neutral conditions, the removal rate does not change much; under strong alkaline conditions, the removal rate of phenol drops sharply. The stronger the alkalinity, the worse the adsorption effect.
