Product Overview
GAC is a coal-based granular activated carbon manufactured from select bituminous coal through carbonization and high-temperature steam activation. Engineered for drinking water and ultra-pure water systems, it delivers an iodine adsorption value exceeding 900 mg/g with a specific surface area above 900 m²/g.
The granular structure provides reliable hydraulic performance in fixed-bed pressure vessels, while the coal base ensures high mechanical strength and cost-effective operation for municipal and industrial water treatment. With controlled ash content and low floating rate, GAC maintains consistent adsorption kinetics for organic contaminant removal and dechlorination.

Key Application Areas
- Ultra-Pure Water Systems — Polishes deionized water in electronics, power generation, and pharmaceutical manufacturing by adsorbing trace organics and chlorine residuals.
- Beverage & Food Processing Water — Purifies ingredient and process water for breweries, soft drink bottling, and food production, ensuring consistent product quality and compliance.
- Point-of-Entry (POE) Water Treatment — Installed at building entry to remove chlorine, taste, and organic precursors from municipal supplies, protecting downstream equipment and residential water quality.
Key Advantage
- Balanced Pore Structure: Coal-based activation develops both micropores for small-molecule adsorption and mesopores for larger organics, ensuring versatile contaminant removal.
- High Mechanical Strength: >90% crush strength withstands backwashing and bed loading without excessive fines generation, extending filter runs and reducing maintenance.
- Cost-Effective Water Treatment: Bituminous coal feedstock provides high adsorption capacity at economical pricing for large-scale municipal and industrial installations.
- Low Floating Rate: <6% floating rate ensures stable bed packing and prevents carbon loss during backwash and hydraulic surges.
