Granular Activated Carbon for Water Treatment, Gas Purification and Fixed-Bed Adsorption
Adsorbent Source supplies granular activated carbon for water treatment, gas purification, odor control, VOC adsorption, filtration systems and selected industrial fixed-bed adsorption applications. We help buyers compare suitable GAC grades according to application, raw material source, particle size, iodine value, hardness, ash content, target impurity, packaging and documentation requirements.
What Is Granular Activated Carbon?
Granular activated carbon, often called GAC, is activated carbon supplied in granular particle form. It is commonly used in fixed-bed filters, adsorption columns and treatment vessels where liquid or gas streams pass through a carbon bed for purification.
Compared with powder activated carbon, granular activated carbon is easier to retain in fixed-bed systems and can be selected where pressure drop, particle strength, flow distribution and contact time are important.
Adsorbent Source helps buyers compare GAC grades, coordinate samples, confirm technical documents and arrange export packaging according to project requirements.
Granular Activated Carbon Compared with Powder Activated Carbon
Granular activated carbon and powder activated carbon are both activated carbon adsorbents, but they are used in different system structures. GAC is usually used in fixed-bed filters and adsorption vessels, while powder carbon is more often used in mixing, batch treatment or decolorization processes.
