8×30 Coal-Based Carbon
for Water Treatment
The cost-effective solution for industrial wastewater and large-scale water treatment. Broad pore structure removes TOC, NOM, dyes, and complex organics that coconut carbon cannot.
The Industrial Workhorse for Water Treatment
Industrial wastewater contains complex organic compounds — dyes, surfactants, humic acids, phenols — that require a carbon with both micropores and mesopores for effective removal. Coal-based activated carbon provides this balanced pore structure naturally, making it the go-to choice for wastewater treatment plants, textile mills, petrochemical facilities, and environmental remediation projects.
Our 8×30 coal GAC is produced from select bituminous coal through steam activation, developing a surface area of 900–1000 m²/g with a well-distributed pore network. The 8×30 mesh size is engineered for industrial filter vessels — providing low head loss at high flow rates while maintaining sufficient kinetics for TOC targets. At 30–40% lower cost per ton than coconut shell, it delivers the best economics for high-volume applications.
