Abstract
Ease of Handling: Granular form simplifies loading and regeneration in fixed-bed reactors.
Regenerability: Can be thermally or chemically regenerated, reducing operational costs.
Versatility: Suitable for both liquid-phase (e.g., water treatment) and gas-phase (e.g., air purification) applications.
Limitations
Flow Resistance: High pressure drops may occur in packed beds if not properly designed.
Selectivity: May require pretreatment or modification (e.g., impregnation with metals) for specific contaminants.
Cost: Higher initial investment compared to powdered activated carbon (PAC), though regenerability offsets long-term expenses.
Regulatory and Safety Considerations
GAC is classified as non-toxic and inert, but dust handling requires precautions to avoid inhalation.
Disposal of spent GAC must comply with local regulations, as it may contain adsorbed contaminants.
Conclusion
Granular series activated carbon remains a cornerstone in adsorption technologies due to its exceptional efficiency, durability, and adaptability. Its role in environmental protection, industrial processes, and emerging fields like energy storage underscores its enduring relevance in modern engineering and sustainability efforts.
