Granular Activated Carbon GAC

Granular Activated Carbon GAC

Description

Granular activated carbon use the high quality bituminious coal as raw materials, production technology refined through series made of black granular appearance. It has enormous effective surface area and its characteristic structure enables a high pressure environment and can be recycled easily.Fully in line with ISO9001-2000 national standard .

Granular activated carbon has a relatively larger particle size, presents a smaller external surface.  Diffusion of the adsorbate into the interior pore surfaces is thus an important factor.  Since the rate of diffusion is related to particle size, the smaller the carbon particle or mesh size, the faster the adsorption (e.g., less contact time is needed).  Granulated carbons are used for water treatment, deodorization and separation of components of a flow system, and are also used in rapid mix basins.  GAC is designated by sizes such as 8×20, 20×40, or 8×30 and 12×40 for liquid phase applications and 4×6, 4×8 or 4×10 for vapor phase applications.  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.
