Activated carbon is made of carbon material with a black appearance, developed internal pore structure, large specific surface area, and strong adsorption capacity. It is commonly used as adsorbent, catalyst, or catalyst carrier.

Activated carbon adsorption technology is mainly used for solution decolorization and adsorption of impurities and heavy metals in pharmaceutical industry.

Cobetter Roheap® CSD activated carbon depth filter combines high-purity wood cellulose with activated carbon powder through a special process, forming a tight three-dimensional structure inside and having a high dirt holding capacity. The filter plate is positively charged, further enhancing its adsorption capacity and achieving good decolorization and deodorization effects.
