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 extremely strong adsorption capacity, which can adsorb organic matter, chromaticity, odor, residual chlorine and other substances in water, as well as toxic and harmful gases in the air. Granular activated carbon has good chemical stability and is not easily corroded by chemicals such as acid and alkali. Granular activated carbon processed by special processes has high mechanical strength, is not easy to break, and is suitable for various complex working conditions.
