Activated carbon Clean and remove dust before use, otherwise these black dust may temporarily affect the cleanliness of water quality. However, it is recommended not to wash directly with fresh tap water, because once the pores of activated carbon absorb a large amount of tap water and bleach, it will damage the water quality when it is put into the filter for use later. However, what are the types of activated carbon?

1. Plant raw materials

Activated carbon has a wide range of wood materials, such as charcoal, coconut shell, sawdust, bark, walnut shell, nut kernel, cotton shell, rice hull, bamboo, coffee bean stem, oil palm shell, furfural residue and pulp waste liquid. Wood raw materials play a very important role in China's activated carbon industry. Among them, coconut shell and walnut shell are superior, but their development is restricted due to limited raw materials.

2. Coal raw materials

Coal is the most important raw material for manufacturing activated carbon. Almost all coal can be made into activated carbon. Among them, young anthracite, weak caking coal, lignite and peat with short coal forming time are excellent raw materials for manufacturing activated carbon. Because coal resources are rich and widely distributed, it has a good prospect to produce activated carbon from coal.
