Nutshell activated carbon treats mercury-containing wastewater. Activated carbon has the effect of adsorbing mercury and mercury, but the adsorption capacity is limited, and it is only suitable for wastewater with low mercury content. If the mercury concentration is high, it can be treated by chemical precipitation, the mercury content is about 1mg/L, up to 2≤3mg/L, and then coconut shell activated carbon manufacturers use activated carbon for further treatment.

Nutshell activated carbon treats phenol-containing wastewater. Phenol-containing wastewater mainly comes from petrochemical plants, resin plants and oil refineries. yongruida carbon pellets The results show that the adsorption capacity of phenol by the shell activated carbon is better, which is not conducive to the reduction of adsorption capacity, but it shortens the adsorption equilibrium when the temperature is increased. Under acidic and neutral conditions, the removal rate and adsorption time of activated carbon from husk are better, and the removal rate of phenol drops sharply under strong alkali conditions. The stronger the alkalinity, the worse the adsorption effect.

Nutshell activated carbon is treated with methanol wastewater. Nutshell activated carbon can adsorb methanol, but the adsorption capacity is not strong. The project results show that the COD of the mixed solution can be reduced from 40mg/L to 12mg/L, and the removal rate of methanol can reach 93.16%≤95%. The effluent water quality can meet the water quality requirements of the boiler desalination system.

Nutshell activated carbon treats chromium-containing wastewater. Chromium is a metal raw material used for electroplating. The 6 types of chromium in wastewater vary with pH. Nutshell activated carbon has strong physical adsorption capacity, strong microporous structure and high specific surface area. It can effectively adsorb CREESEA in wastewater. There are a large number of oxygen-containing substances on the surface of activated carbon from the shell, such as hydroxyl (OH) and carbon-based (COOH). coconut activated charcoal They all have electrostatic adsorption function. The process of coconut shell activated carbon manufacturers using activated carbon to treat chromium-containing wastewater is a comprehensive effect of physical adsorption and chemical recovery of activated carbon in solution. Nutshell activated carbon has stable adsorption performance, high treatment efficiency and low operating cost for treating chromium-containing wastewater, and has certain social and economic benefits.

 Nutshell activated carbon is treated with cyanide wastewater. Coconut shell activated carbon manufacturers in industrial production, or by-products are used to extract chemical fiber production. Therefore, a certain amount of cyanide sewage must be discharged during the production process. Nutshell activated carbon has long been used to purify wastewater. There are also more and more reports in the literature for the treatment of cyanide-containing wastewater. However, the adsorption capacity of CN_HCN to activated carbon is relatively small. In general, 3mgCN/GAC~8mgCN/gAC is not cost-effective in terms of processing costs.
