Introduction to Powdered Activated Carbon:

Powdered activated carbon is produced from high-quality coal through physical or chemical activation methods, resulting in micron-sized particles with a highly porous structure and strong adsorption capabilities. Compared to granular activated carbon, powdered activated carbon has smaller particle sizes and a higher specific surface area, which gives it superior performance in adsorbing organic pollutants in water, removing odors, decolorizing, purifying gases, and eliminating certain heavy metal ions and other contaminants.

Characteristics of Powdered Activated Carbon:
It appears as a black powder, odorless and tasteless, and is insoluble in common solvents.

Main Functions of Powdered Activated Carbon:
(1) Decolorization: Removal rates can reach up to 70%, though decolorization effectiveness is not directly proportional to the dosage;
(2) Odor removal.
(3) Helps remove anionic detergents.
(4) Aids in the removal of algae.
(5) Reduces chemical oxygen demand (COD) and five-day biochemical oxygen demand (BOD5).
(6) Removes phenols.
(7) Reduces turbidity.

Applications of Powdered Activated Carbon:

Powdered activated carbon is widely used in wastewater treatment, chemical wastewater, pharmaceutical wastewater, air purification, food and beverage industries, and more. It is particularly important for removing micropollutants from water and improving water quality. Due to its high adsorption efficiency and environmental friendliness, powdered activated carbon has broad application prospects in environmental protection and purification fields.

For example:

Wastewater Treatment: Powdered activated carbon is commonly used in wastewater purification. It exhibits excellent adsorption performance for aniline, achieving 80%–90% adsorption capacity within 30 minutes.

Chemical Industry: Chemical wastewater often contains hard-to-degrade organic matter and heavy metal ions. Powdered activated carbon can effectively adsorb these substances, improving the biodegradability of wastewater.

Pharmaceutical Industry: Pharmaceutical wastewater typically contains complex organic compounds and residual drug components. Powdered activated carbon can remove these hard-to-degrade organic pollutants.

Food and Beverage: Wastewater from these industries contains large amounts of organic matter and color. Powdered activated carbon can remove these substances, allowing the wastewater to meet discharge standards.

Research on the adsorption characteristics of powdered activated carbon with different particle sizes shows that it has excellent adsorption performance for aniline, achieving 80%–90% adsorption capacity within 30 minutes. Additionally, the specific surface area of powdered activated carbon correlates well with the saturated adsorption capacity of soluble organic matter. As the particle size decreases, its adsorption efficiency for organic matter improves.
