The base carbon is treated with unique processes such as acid solution, alkali solution, or chemical impregnation to adjust pH, reduce ash, iron, and load, producing aid washing activated carbon, alkali washing activated carbon and carrier activated carbon respectively.
Acid washing activated carbon is specially used for decolorization and deodorization of alkaline sewage, and fine decolorization processes in food and medicine manufacturing.
Alkali washing activated carbon can be used as special carbon for solvent recovery, refrigerator deodorization, and high-efficiency industrial H2S removal.
Carrier activated carbon can be used as a special carrier carbon for formaldehyde removal, indoor VOCs removal, and restroom ammonia removal. The main application areas are efficient adsorption and degradation of formaldehyde and VOCs gases in industrial rooms; TVOC adsorption and degradation and formaldehyde absorption in civil rooms, etc.
