• Powdered Activated Carbon (PAC) : Powdered Activated Carbon refers to a kind of activated carbon that is formed with fine particles and has a large surface to volume ratio. It helps bring better effectiveness in contamination absorbtion.
• Granular Activated Carbon (GAC): Granular Activated Carbon is relatively bigger than PAC particles and they come with smaller outside surface areas. It is a type of activated carbon that is extensively used for vapors & gases adsorption and air purification as it comes with quick diffusing features. Thus, GAC can be referred to as a prominent kind of carbon leveraged in water treatment plants across many corners of the globe.
• Pelletized Activated Carbons: It is one of the prominent types of activated carbon that is widely utilised across many industries like healthcare, food & beverages, water treatment, among other industries. They mainly fuse with PAC and create a binding agent.

Other than these, there are certain other varieties like Coconut shell-based activated carbon., Coal-based activated carbon, Wood based activated carbon, Catalytic based activated carbon, Impregnated Activated Carbon and more. All of these are used in industry specific applications.
