Sewage Treatment Activated Carbon Application Introduction
Activated carbon has become an essential filter material for advanced sewage treatment, widely used in industrial wastewater upgrading, municipal sewage depth purification and reclaimed water reuse projects. With developed microporous structure and large specific surface area, it features stable physical adsorption performance, which effectively makes up for the deficiencies of conventional coagulation, precipitation and biochemical treatment processes.
Industrial sewage such as printing and dyeing, chemical and electroplating wastewater contains residual pigments, organic additives, trace heavy metals and refractory macromolecular organics. These residual pollutants are difficult to remove by conventional processes, leading to excessive chroma and COD. Activated carbon can efficiently adsorb these tiny pollutants, reduce water turbidity and eliminate abnormal color, enabling tail water to meet discharge and reuse standards.
In actual operation, activated carbon is usually arranged in the final stage of the water treatment process as a polishing treatment unit. It adapts to fluctuating water quality with stable purification effect and simple operation. After long-term operation, the carbon will reach adsorption saturation and needs regular replacement or regeneration to avoid secondary pollution. It is a cost-effective and reliable purification material for sewage advanced treatment.
