Activated Carbon Types and Applications in Wastewater Treatment
In the field of activated carbon applications, products are typically classified based on their physical form. The most common types include extruded activated carbon (EAC), powdered activated carbon (PAC), and granular activated carbon (GAC) made from coconut shells or other nut shells. Each type offers unique performance characteristics, making it essential to choose the right form for specific wastewater treatment and filtration needs.
Powdered activated carbon (PAC) is available in various particle sizes and is known for its high surface area and rapid adsorption capacity. It is widely used in industrial water treatment processes for emergency dosing and targeted applications such as decolorization, deodorization, and chemical adsorption. PAC is also commonly applied in desulfurization and catalytic processes. However, due to its fine particle size, PAC is difficult to recover and handle, which limits its use in continuous filtration systems.
Extruded activated carbon (EAC), also known as pelletized activated carbon, offers high mechanical strength, a stable structure, and excellent durability. It is easy to handle, load, and regenerate, making it ideal for continuous filtration systems and long-term wastewater treatment operations. Common diameters include 2mm, 4mm, 6mm, and 8mm, allowing flexible selection for different industrial conditions. EAC is highly effective in removing organic contaminants, odors, and impurities, and is widely used in industrial wastewater treatment, air purification, drinking water filtration, and aquarium filtration systems.
Granular activated carbon (GAC), especially those made from coconut shell raw materials, is also widely used in water purification due to its high hardness and excellent adsorption performance. It is particularly suitable for drinking water treatment and applications requiring high purity.
In summary, for continuous filtration and long-term wastewater treatment systems, extruded activated carbon is generally the preferred choice. Powdered activated carbon is more suitable for short-term dosing and auxiliary treatment processes, while granular activated carbon provides a balanced solution for many water purification applications.
