Coal-Based Powdered Activated Carbon

High Adsorption Capacity

· Selling Point: Coal-based powdered activated carbon has a strong adsorption capacity, capable of rapidly and extensively adsorbing organic matter, heavy metal ions, pigments, odors, and other impurities from water. In industrial wastewater treatment, it can effectively reduce the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD), helping wastewater meet discharge standards. In drinking water purification, it removes residual chlorine, pesticide residues, and other harmful substances, providing safe and healthy drinking water.

· Feature: It has a highly developed pore structure and a large specific surface area, reaching 500–1500 m² per gram. The pores vary in size — micropores adsorb small molecules, while mesopores and macropores allow the diffusion and adsorption of larger molecules — achieving efficient adsorption of pollutants with different sizes and properties.

High Cost Performance

· Selling Point: Compared with other types of activated carbon, such as coconut shell activated carbon, coal-based powdered activated carbon has lower production costs and is more affordable. In large-scale applications such as water treatment and air purification, the use of coal-based powdered activated carbon can significantly reduce treatment costs without compromising performance, saving considerable expenses for enterprises.

· Feature: Coal is an abundant and relatively inexpensive raw material. Using coal as the feedstock for activated carbon production offers advantages in both raw material acquisition and processing costs. Moreover, the production process for coal-based powdered activated carbon is mature and efficient, ensuring large-scale and stable market supply, which further reduces product prices.

Excellent Chemical Stability

· Selling Point: Coal-based powdered activated carbon has excellent chemical stability and can maintain consistent performance in various chemical environments. It is resistant to acids, alkalis, and high temperatures, making it suitable for harsh industrial conditions. It does not react with chemicals that would otherwise reduce adsorption efficiency, ensuring reliable and stable performance throughout the treatment process.

· Feature: Its main component is carbon, which is chemically stable. It is not easily soluble or reactive in acidic or alkaline solutions, thus maintaining its structure and performance over time. Even under high-temperature conditions, coal-based powdered activated carbon does not easily decompose or deteriorate, making it suitable for processes that require high-temperature treatment.

Good Regeneration Performance

· Selling Point: Used coal-based powdered activated carbon can be regenerated to restore its adsorption capacity, allowing for multiple reuse cycles. This not only reduces usage costs but also minimizes waste generation, aligning with environmental protection and sustainable development goals. For enterprises with strict cost control requirements, the regeneration and reuse of activated carbon can greatly enhance economic efficiency.

· Feature: The pore structure and surface properties of coal-based powdered activated carbon make it easy to regenerate. Common regeneration methods include thermal regeneration and chemical regeneration. During thermal regeneration, the pollutants adsorbed in the pores are decomposed or volatilized at high temperatures, reopening the pores and restoring adsorption capacity.

Wide Range of Applications

· Selling Point: Coal-based powdered activated carbon is suitable for purification and treatment processes across multiple fields. In water treatment, it can be used for industrial wastewater treatment, drinking water purification, and swimming pool water purification. In air purification, it removes harmful gases and odors from indoor and outdoor air, improving air quality. In the food, pharmaceutical, and chemical industries, it is used for decolorization, purification, and refining processes.

· Feature: Owing to its excellent adsorption properties and chemical stability, it can adapt to complex environments and treatment requirements in various fields. Different application scenarios can achieve optimal treatment results by adjusting parameters such as particle size, pore structure, and surface characteristics of the activated carbon.
