Granular activated carbon is divided into shaped particles and amorphous particles. It is mainly made of coconut shell, fruit shell and coal as raw materials, and refined through a series of production processes. Products are widely used in drinking water, industrial water, wine making, waste gas treatment, decolorization, desiccant, gas purification and other fields. Granular activated carbon is made of high-quality anthracite as raw material, refined and processed by advanced technology, and its appearance is black amorphous particles. It has the advantages of developed pore structure, good adsorption performance, high mechanical strength, easy repeated regeneration, low cost, etc.; used for the purification of toxic gases, waste gas treatment, industrial and domestic water purification, solvent recovery, etc.
