Powdered Activated Carbon: Characteristics and Applications
Powdered activated carbon (PAC) is a fine porous adsorbent made from high-quality wood coal and anthracite through high-temperature activation and fine grinding. Compared with columnar and honeycomb activated carbon, it has a larger specific surface area and finer particle size, enabling faster adsorption speed and more sufficient contact reaction with pollutants. It is widely used in water purification, waste gas treatment and industrial decolorization, serving as an essential material for fine environmental purification.
PAC features developed micropore structures, which can effectively adsorb tiny pollutants in water and gas. In water treatment, it removes residual chlorine, peculiar smell, color, organic impurities and trace heavy metals, widely applied in tap water purification and sewage advanced treatment. In industrial waste gas management, it efficiently absorbs VOCs, lampblack odor and harmful smoke particles, adapting to complex and variable working conditions.
With flexible one-time dosing and mixed adsorption mode, PAC requires no fixed equipment, featuring high purification accuracy and stable decolorization and deodorization performance. It is ideal for purification and decolorization in food, pharmaceutical and chemical industries. Despite drawbacks like easy dusting, high wind resistance and non-reusability, its efficient adsorption and convenient use make it perfect for fine purification and emergency treatment.
