Powdered Activated Carbon: Properties and Applications
Powdered activated carbon (PAC) is a fine-grained adsorbent with a large specific surface area and abundant microporous structure, made from raw materials such as coal, coconut shell, and wood through carbonization and activation processes. Its unique physical and chemical properties make it widely used in water treatment, air purification, and industrial pollution control.
In water treatment, PAC is highly effective in removing organic pollutants, odors, and residual chlorine, improving water quality and ensuring safety. It is also used in industrial processes to adsorb harmful gases and impurities, helping enterprises meet environmental standards. Compared with granular activated carbon, PAC has faster adsorption speed and higher adsorption capacity for small-molecule pollutants.
Easy to use and low in cost, PAC is a versatile and efficient adsorbent. It can be directly added to treatment systems, adapting to different working conditions. Proper dosage control and treatment conditions are essential to maximize its adsorption efficiency.
