Granulated Activated Carbon (GAC) is a highly porous adsorbent material, commonly used in water and air purification processes. Its large surface area and pore structure make it exceptionally effective at removing impurities and contaminants through adsorption. GAC is widely employed in applications such as water treatment, air purification, and industrial processes to eliminate organic compounds, chlorine, and harmful pollutants. Its versatility and high efficiency make it a critical component in ensuring clean and safe water and air in various settings.
