Product Overview
LAC is a standard coal-based granular activated carbon manufactured from select bituminous coal for drinking water, ultra-pure water, and food-grade water treatment. Produced through carbonization and high-temperature steam activation, it delivers an iodine adsorption value exceeding 900 mg/g with a specific surface area above 900 m²/g.
Available in LAC 830 and LAC 1240 configurations, this grade provides reliable organic removal and dechlorination for municipal and industrial water systems. With controlled moisture, ash, and floating rate, LAC maintains consistent hydraulic performance in fixed-bed pressure vessels while offering the cost advantages of coal-based manufacturing.

Key Application Areas
- Ultra-Pure Water Treatment — Polishes deionized water for electronics, power generation, and laboratory applications where standard organic removal is required.
- Beverage Processing Water — Purifies ingredient water for breweries, soft drink bottling, and food manufacturing, supporting consistent product quality.
- Point-of-Entry (POE) Water Systems — Provides whole-building protection against chlorine, taste, and organic contaminants in residential and commercial water supplies.
Key Advantages
- Proven Coal-Based Performance: Iodine >900 mg/g and surface area >900 m²/g deliver reliable dechlorination and organic removal for standard-duty water treatment.
- High Mechanical Strength: >90% crush strength withstands backwashing and bed loading without excessive attrition, maintaining stable bed permeability.
- Low Floating Rate: <6% floating rate ensures stable bed packing and prevents carbon loss during hydraulic surges and backwash cycles.
- Cost-Effective Municipal Supply: Bituminous coal feedstock and mature manufacturing ensure competitive pricing for large-scale continuous operations.
