Our Granular Activated Carbon has a relatively larger particle size compared to powdered activated carbon and consequently, presents a smaller external surface. Diffusion of the adsorbate is thus an important factor. These carbons are therefore preferred for all adsorption of gases and vapors as their rate of diffusion are faster. Granulated carbons are used for water treatment, deodorization and separation of components of flow system. Gac can be either in the granular form or extruded. Gac is designated by sizes such as 8×20, 20×40, or 8×30 for liquid phase applications and 4×6, 4×8 or 4×10 for vapor phase applications. A 20×40 carbon is made of particles that will pass through a u.s. Standard mesh size no. 20 sieve (0.84 mm) (generally specified as 85% passing) but be retained on a u.s. Standard mesh size no. 40 sieve (0.42 mm) (generally specified as 95% retained). Awwa (1992) b604 uses the 50-mesh sieve (0.297 mm) as the minimum gac size. The most popular aqueous phase carbons are the 12×40 and 8×30 sizes because they have a good balance of size, surface area, and head loss characteristics.

We have Powdered Activated Carbon. Powdered varieties of activated carbon are used in liquid phase application primarily for removal of undesired colour, smell & other impurities in many types of industries including basic drugs, fine chemicals, glucose, sugar, electroplating plasticizers and so on. Quite often, powdered carbon is washed with acid and then, repeatedly with water & dried to minimize impurities like soluble ash-iron, heavy metals etc. Activated carbon is invariably used in a batch process at the penultimate stage of manufacture of a product. A pre-determined quantity of activated carbon is added to a solution and after stirring for a certain contact time mostly at elevated temperature carbon is filtered out or settled to get a sparkling colour free solutions from which product is recovered.
