GAC is a form of irregular shaped activated carbon with particle size greater than 0.2 mm (70 ASTM Mesh).
Owing to their larger particle size compared to PAC and superior mechanical properties they are mainly used in applications with rigorous process conditions such as high flow rate and pressure drop. Particle sizes between 0.2 to 2 mm are typically used for liquid phase applications because rate of adsorption is more important than pressure drop issue, and between 2 to 5 mm are typically used for gas/vapor phase applications because pressure drop is a more critical factor than rate of adsorption.
SHAKUN MINERALS PVT LTD provides GAC derived from 2 raw materials viz., coal and coconut shell, each available in various mesh sizes and standard as well as customizable properties. We have the capability to manufacture GAC through both steam activation and chemical activation routes. We also offer unwashed, water washed and acid washed grades with tailorable adsorption properties.
