The raw materials for activated carbon are very diverse, mainly including fruit shells (such as coconut shells, peach shells, apricot shells, jujube shells, etc.), wood, coal, petroleum coke, etc. These raw materials undergo high-temperature carbonization and activation treatment to form activated carbon with rich pore structure and huge specific surface area. Activated carbon is a powerful porous carbon containing substance with a huge specific surface area and highly developed pore structure. It can adsorb various substances and is widely used in multiple fields.

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.
