The adsorption performance of activated carbon mainly comes from its highly developed pore structure and huge specific surface area. These pores can effectively adsorb organic matter, chromaticity, odor, residual chlorine and other substances in water, as well as toxic and harmful gases in the air. The adsorption process of activated carbon is usually non selective and can adsorb various substances, but it can also be selectively adsorbed through specific treatments.

When selecting granular activated carbon, attention should be paid to the raw materials, production process, adsorption performance and other indicators of the product, and products produced by legitimate manufacturers should be selected. Granular activated carbon should be stored in a dry, cool, and ventilated place, avoiding direct sunlight and high temperatures. During storage, attention should be paid to measures such as moisture prevention, fire prevention, and pollution prevention.
