Granular Activated Carbon feed

Granular activated carbon has a relatively larger particle size compared to the powdered activated carbon, which presents a smaller external surface. Thus diffusion of the adsorbate is an important factor. This carbon is therefore preferred for all adsorption of gases and vapors as their rate of diffusion is faster. Granular carbon is 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 it has a good balance of size, surface area, and head loss characteristics.
