Activated Carbon for Wastewater Filtration
Activated carbon is an essential deep filtration material widely used in municipal and industrial wastewater treatment. With developed micropore structure and huge specific surface area, it features strong physical adsorption capacity, good abrasion resistance and stable water permeability, which perfectly meets the advanced purification requirements of sewage systems.
Conventional sewage filtration can only remove large suspended particles, while many soluble organic pollutants, residual pigments, odor substances and trace heavy metals still remain in the water. Activated carbon effectively adsorbs these tiny harmful contaminants, reduces water chroma and peculiar smell, and lowers the chemical oxygen demand of wastewater. It greatly improves water clarity and quality, making sewage meet discharge or reuse standards.
In practical treatment processes, activated carbon is usually applied after sand filtration and sedimentation as a deep purification procedure. Long-term water flow will saturate its pores and weaken filtration performance. Regular backwashing and timely replacement are required to maintain stable treatment effect. It has become an economical and reliable material for modern sewage purification and environmental protection treatment.
