Powdered activated carbon is made from high-quality sawdust, coconut shell, and coal through a series of production processes. Powdered activated carbon has the advantages of fast filtration, good adsorption performance, strong decolorization, and odor removal ability, economy, and durability. Powdered activated carbon can be made according to user requirements in different adsorption capacities of different bleaching, the level of activated carbon with different fineness. Powdered activated carbon at high speed, with flocculation effect and filtering effect.
