Granular Activated Carbon (GAC)
Versatile granular carbon for continuous-flow filtration systems.
Product Overview
Granular Activated Carbon (GAC) is the most widely used form of activated carbon, designed for continuous-flow fixed-bed adsorption systems. The irregular granular shape provides excellent flow distribution and high contact area, making it ideal for both liquid-phase and gas-phase applications.
Available in both coal-based and coconut shell-based varieties with multiple mesh sizes, our GAC products can be tailored to specific flow rates, contact times, and target contaminants. GAC can be regenerated thermally for multiple reuse cycles, offering long-term cost advantages.
Key Applications
- Drinking water filtration
- Wastewater polishing
- Groundwater remediation
- Swimming pool filtration
- Aquarium filtration
- Air & gas purification
- PFAS removal
- Chloramine removal
