Coal-based activated carbon is a high-performance adsorbent produced through carbonization, cooling, activation and washing. Also known as coal-based granular activated carbon, it appears as black granules with a well-developed pore structure and a very large specific surface area, effectively adsorbing harmful substances in air and water.
1. Purifying water and safeguarding drinking water safety
Coal-based activated carbon is widely used in drinking water treatment, efficiently removing taste and odour, organics, residual chlorine, disinfection by-products and pesticide residues. Its abundant micropore structure gives it a strong capacity for adsorbing small-molecule organic pollutants, markedly improving the taste and safety of treated water.
2. Treating industrial wastewater and cutting pollutant discharge
In industrial wastewater treatment, coal-based activated carbon removes COD, colour, heavy metals and recalcitrant organics. Acid-wash post-treatment further reduces ash and iron content, allowing effluent to meet stricter discharge or reuse standards.
3. Air purification and VOC abatement
Coal-based activated carbon is equally suited to air purification and industrial off-gas treatment. It adsorbs volatile organic compounds (VOCs), hydrogen sulphide, ammonia and other harmful gases, and is widely used in indoor air purification, respirators, solvent recovery and flue-gas desulfurization and deodorization.
4. Reactivation for a circular, greener process
Spent coal-based activated carbon can be thermally reactivated to restore its adsorption performance and be reused. This reduces solid waste and lowers the customer's overall carbon cost, in line with sustainable development principles.
Datong Guiyi Carbon uses premium Datong Jurassic coal and advanced activation technology to produce high-performance coal-based activated carbon, providing reliable material support for water treatment, air purification and industrial pollution control.
