How To Use Activated Carbon In Water Treatment
Activated carbon is a specially treated carbon with numerous tiny pores and a huge surface area, with a surface area of 500-1500 square meters per gram of activated carbon. Activated carbon has strong physical adsorption and chemical adsorption functions, and also has a detoxification effect. The detoxification function is to use its huge area to adsorb the poison in the air of the activated carbon, thereby preventing the absorption of the poison. At the same time, activated carbon can bind to a variety of chemical substances, thereby preventing the absorption of these substances. Because activated carbon has high requirements for water pretreatment and the price of activated carbon is expensive, in wastewater treatment, activated carbon is mainly used to remove trace pollutants in wastewater, which has achieved the purpose of deep purification. (1) Activated carbon treatment of chromium-containing wastewater Chromium is a metal raw material with a large amount in electroplating, and hexavalent chromium exists in different forms in wastewater with different pH. Activated carbon has a very developed microporous structure and high specific surface area, and has strong physical adsorption capacity, which can effectively adsorb Cr(VI) in wastewater. There are a large number of oxygen-containing groups on the surface...
