The adsorption performance of activated carbon mainly comes from its highly developed pore structure and huge specific surface area. These pores can effectively adsorb organic matter, chromaticity, odor, residual chlorine and other substances in water, as well as toxic and harmful gases in the air. The adsorption process of activated carbon is usually non selective and can adsorb various substances, but it can also be selectively adsorbed through specific treatments.

Granular activated carbon has a wide range of applications in water treatment, such as tap water purification, industrial wastewater treatment, electroplating wastewater treatment, etc. It can remove harmful substances from water and improve water quality. Granular activated carbon can be used in air purification equipment to adsorb toxic and harmful gases in the air, such as formaldehyde, benzene, ammonia, etc., and improve indoor air quality.
