Powdered activated carbon
Powdered activated carbon is used for the treatment of liquids in the chemical, pharmaceutical and food industries, as well as in water treatment and as a catalyst carrier. It is also used suspended or mixed with a calcium-based sorbent in the final stage of exhaust gas treatment. Powdered activated carbon products differ in the proportions of micro and macro pores they contain, depending on the input material used in production. This affects the material’s suitability for different applications: activated carbon from coconut shells is suitable for trapping small molecules (perchloroethylene and trichlorethylene in degreasing), while wide-pore activated carbon made from wood is appropriate for decolouring.
