Granular activated carbon (GAC) is produced from high‑carbon raw materials such as coconut shell or coal and is characterized by particle sizes retained on a 50‑mesh sieve, making it ideal for fixed‑bed and continuous filtration systems in water and air treatment. Engineered through precise carbonization and activation to develop extensive internal porosity, GAC delivers robust adsorption performance across liquid‑ and gas‑phase applications, including municipal and industrial water purification, VOC and odor control, solvent recovery, and food and sugar decolorization. Offered in multiple raw‑material bases, mesh sizes, and activation levels, it can be tailored to meet demanding process, environmental, and regulatory requirements across diverse industries.
