Product Overview
Coal granular carbon water treatment 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.
How LAC Delivers Coal Granular Carbon Water Treatment
Municipal and industrial water treatment systems require consistent dechlorination, organic removal, and reliable hydraulic performance across variable flow rates. Standard low-iodine carbons may achieve basic chlorine reduction but struggle with organic precursors, taste-and-odor compounds, and seasonal loading spikes—leading to premature breakthrough and compromised effluent quality.
LAC solves this through proven coal-based activation. The coal granular carbon water treatment base develops both micropores for small-molecule adsorption and mesopores for larger organics, ensuring versatile contaminant removal. In fixed-bed pressure vessels, the granular structure maintains low pressure drop and stable bed packing through repeated backwashing. The >90% crush strength and <6% floating rate ensure minimal attrition and carbon loss during hydraulic surges. The result is reliable, cost-effective water treatment for municipalities and industrial plants with continuous demand.
LAC vs GAC and Enhanced LAC-P
GAC provides comparable coal-based granular performance with similar specifications for drinking water and ultra-pure water. LAC-P delivers >1000 mg/g iodine for enhanced capacity in high-duty process and reclaimed water systems.
LAC bridges this gap as the standard coal granular carbon water treatment solution. It offers the same proven >900 mg/g iodine foundation and high mechanical strength as GAC, with selection often depending on specific supply chain, certification, or regional availability. For standard-duty municipal drinking water, ultra-pure water, and beverage processing where 900 mg/g iodine is sufficient, LAC provides economical and reliable performance. Choose LAC-P for higher organic loading or tighter effluent requirements; select coal granular carbon water treatment LAC for consistent, cost-effective standard-duty systems.
