Introduction to activated carbon filtration

Water filtration treatment process using activated carbon as filter media.
The surface area of ​​activated carbon per gram is 500-1700m, and the true specific gravity is 1.9-2.1.
During filtration, due to its porosity, it can adsorb fine substances in various liquids. It is often used in water treatment for decolorization, deodorization, dechlorination, removal of organic matter and heavy metals, removal of synthetic detergents, bacteria, viruses and radioactive pollutants, and is also commonly used in tertiary treatment of wastewater.
Activated carbon filters are divided into three types: fixed bed, moving bed and fluidized bed. The fixed bed filtration rate is generally 8-20m/h. The activated carbon is regenerated by high-temperature steam cleaning or thermal regeneration, and the recovery rate can reach 80-94%.

Introduction
Activated carbon filtration is a process of water treatment using activated carbon as filter media. Activated carbon is a black solid substance with carbon as a skeleton structure, which has developed pores through gasification (carbonization, activation). Its developed pores give it a large specific surface area, with a surface area of ​​500-1700㎡ per gram of material, thus having good adsorption characteristics. The true specific gravity of activated carbon is 1.9 to 2.1.
