Powder activated carbon (PAC) stands as a pivotal purification agent renowned for its exceptional adsorption capabilities, serving a myriad of applications across liquid and gas phases. As a counterpart to granular activated carbon (or GAC), powder activated carbon boasts distinctive properties and utilities, making it a cornerstone in various purification processes.

What is Powder Activated Carbon?

Powder activated carbon represents a finely ground form of activated carbon, characterised by its minute particle size. Typically, powder activated carbon particles measure below 0.2mm (200 microns), distinguishing them from the larger granules of granular activated carbon (GAC). This finely powdered state enhances its surface area, augmenting its adsorption efficiency and reaction kinetics, rendering it ideal for specific purification tasks.

Powder Activated Carbon Manufacture and Composition

Similar to granular activated carbon, powder activated carbon is crafted from premium-grade carbonaceous materials such as bituminous coal, coconut shells, or select wood types. These raw materials undergo a meticulous activation process, wherein they are subjected to high temperatures in a carefully controlled environment, resulting in the formation of a highly porous structure conducive to adsorption.
