Powdered activated carbon (PAC) is a versatile adsorbent material widely used across industries for purification, decolorization, and contaminant removal. With its high surface area and porous structure, PAC effectively traps impurities at a molecular level.
PAC is classified based on raw materials and activation methods, each offering distinct properties:
Wood-Based PAC
Derived from sawdust, coconut shells, or other lignin-rich biomass, wood-based PAC excels in removing organic compounds and odors. Its high microporosity makes it ideal for:
Food and beverage decolorization (e.g., sugar refining)
Pharmaceutical purification
Indoor air filtration systems
Coal-Based PAC
Produced from bituminous or anthracite coal, this type has a robust structure and higher density. Key uses include:
Municipal and industrial wastewater treatment
Heavy metal removal (e.g., mercury, lead)
Flue gas desulfurization in power plants
Coconut Shell PAC
Made from sustainably sourced coconut shells, this variant offers exceptional adsorption capacity for volatile organic compounds (VOCs) and chlorine. It’s preferred for:
Drinking water purification
Gold recovery in mining
Gas mask filters
Recycled/Reactivated PAC
Environmentally conscious industries increasingly adopt reactivated PAC, which undergoes thermal regeneration to restore adsorption efficiency.
1. Water Treatment
PAC removes contaminants like pesticides, PFAS, and disinfection byproducts. Municipalities and bottling plants rely on PAC to meet WHO water safety standards.
2. Air & Gas Purification
PAC filters harmful gases (e.g., hydrogen sulfide, ammonia) in industrial exhaust systems and HVAC units, ensuring compliance with air quality regulations.
3. Food & Pharmaceutical Processing
PAC decolorizes syrups, oils, and antibiotics while eliminating off-flavors. Its FDA/EC compliance makes it safe for consumables.
4. Industrial Processes
PAC optimizes chemical manufacturing by removing catalyst poisons and recovering precious metals in electroplating.
5. Environmental Remediation
Used in soil stabilization and landfill leachate management, PAC mitigates ecological risks from hazardous pollutants.
