Wood based granular activated carbon

Irregular granulated activated carbon is used high quality wood and special sawdust as raw materials.

Irregular granulated activated carbon is used high quality wood and special sawdust as raw materials. It should be refined by many working procedures, It is characterized with strong adsorption power, low impurity content and good filtering ability, they are commonly used for decolorizing, refining and purifying various medicine injections and chemical raw materials.
