Product Description Granular Activated Charcoal Granular Activated Charcoal (GAC) is a highly porous form of activated carbon that is used in a wide range of applications, including water and air purification, gas and vapor adsorption, and chemical and pharmaceutical processing. It is produced by heating carbon-rich materials, such as coconut shells or wood, in the absence of air, which creates a highly porous material with a large surface area. The surface area of GAC can range from 500 to 1500 square meters per gram, depending on the specific production process and the pore size distribution. This high surface area and porosity give GAC excellent adsorption properties, allowing it to attract and retain a wide range of organic and inorganic compounds. GAC is commonly used in water treatment applications, where it is used to remove impurities such as chlorine, volatile organic compounds (VOCs), pesticides, and other organic contaminants. It can also be used to remove odors and flavors from water.
