Activated carbon pellets are highly porous granules or pellets made from carbon-rich materials like coal, wood, coconut shells, or other carbon sources. They are subjected to an activation process, usually through heat treatment at high temperatures in the presence of steam or carbon dioxide, which creates a network of pores and increases their surface area. This unique structure enables them to effectively adsorb and capture a wide range of impurities, contaminants, and pollutants from gases or liquids
