Granular Activated Carbon (GAC) is a form of activated carbon with larger particle size compared to powdered carbon. It is produced from raw materials like coconut shell, coal, or wood through high-temperature activation. Its porous structure and large surface area make it highly effective for adsorption of organic and inorganic contaminants. GAC is typically used in fixed-bed filters, adsorption columns, and water/air purification systems.

Activated Carbon Specifications
Technical Parameters & Performance Guidelines
Iodine Value
The Iodine Value is the most common parameter to measure the performance of activated carbon. It indicates the adsorption capacity of carbon — specifically the amount of micropores available to trap contaminants.
Higher iodine value = higher adsorption capacity
Typical Range: 600 – 1200 mg/g
Click on the range bar or markers to see performance details at different iodine values.

Mesh Size
Mesh size defines the particle size of GAC (how coarse or fine it is).
It affects flow rate, contact time, and filtration efficiency.
Standard GAC Mesh Sizes
(2.36–4.75 mm)
Large Particles
Low pressure drop, used in air/gas treatment applications
(1.18–2.36 mm)
Balanced Size
Ideal for water purification systems
(0.425–1.70 mm)
Fine Size
High adsorption efficiency, used in drinking water, pharmaceutical & food industry
(0.297–0.850 mm)
Very Fine
Used in special applications requiring maximum surface area
