Powdered activated carbon is milled and sieved and has a smaller particle size than GAC. The PAC particles are mainly less than 0.18 mm (80 mesh) usually with a median diameter of 15 to 30 microns. PACs are generally used in liquid phase applications and for flue gas treatment.
The activated carbon has been extruded into cylindrical shaped pellets with diameters ranging from 0.9 to 9 mm. These are mainly used for gas phase applications because of their low pressure drop, high mechanical strength and low dust content.
The activated carbon is milled and sieved to achieve particles in the range of 0.2 to 5 mm. Typically the drinking water industry uses an 8 x 30 mesh (effective size of 0.80-1.0 mm), or a 12 x 40 mesh (effective size of 0.5 - 0.7 mm). GAC is used in both liquid and gas phase applications.
