Coal-based activated carbon

In addition to coal-based activated carbon, there are other types, such as wood-based activated carbon and fruit shell activated carbon. Wood-based activated carbon is typically made from high-quality wood, available in powdered and granular forms, mainly used for absorbing impurities in liquids. Fruit shell activated carbon, made from materials like fruit shells and coconut shells, boasts high specific surface area and strong adsorption properties, commonly used in water treatment and air purification fields.
