Granular Activated Carbon Manufacturer & Producer
Granular Activated Carbon (GAC): High-Performance Adsorbents for Air and Water Purification
Granular Activated Carbon (GAC) from Global Adsorbents is engineered for efficient removal of contaminants through both physical adsorption and chemical interaction. Its highly porous structure, developed from premium-grade raw materials, captures pollutants across multiple pore sizes, while surface functional groups enable selective bonding with organic and inorganic compounds. The result is reliable, high-capacity adsorption performance for air treatment, water purification, industrial gas filtration, and solvent recovery applications—trusted by OEMs and process industries worldwide for consistent quality and sustainability.
Coconut Shell-Based Granular Activated Carbon
This is the most common and popular base for Granular Activated Carbon. It is known for its excellent hardness and high concentration of micropores.
Key Properties: Exceptionally hard, high density, and a very large internal surface area dominated by micropores (perfect for small molecule adsorption).
Key Properties: Exceptionally hard, high density, and a very large internal surface area dominated by micropores (perfect for small molecule adsorption).
Key Properties:
Water Treatment
Removing chlorine, taste, odor, and small organic molecules from drinking water.
Gold Recovery
Its hardness and high density make it highly effective in Carbon-in-Pulp (CIP) and Carbon-in-Leach (CIL) processes for gold extraction.
Solvent Recovery
Capturing and recovering solvent vapors.
Air Purification
Removing volatile organic compounds (VOCs) and other small airborne contaminants.
Impregnation
We also offer impregnated granular activated carbon, including the ABEK series, MGO, Silver impregnated grades, etc., depending on industry
requirements.
requirements.
Coal-Based Granular Activated Carbon
Derived from bituminous or anthracite coal, this GAC has a balanced pore structure with a mix of micropores and mesopores.
Key Properties:
Versatile pore structure, good hardness, and cost-effective.
Applications:
Industrial Water Treatment
A workhorse for treating industrial wastewater and process water, as its larger pores can handle a wider range of organic compounds.
Groundwater Remediation
Effective in removing contaminants from contaminated groundwater.
Municipal Water Treatment
Commonly used in large-scale municipal water treatment plants.
Wood-Based Granular Activated Carbon
Wood-based Granular Activated Carbon typically has the largest pore structure, with a high concentration of mesopores and macropores.
Key Properties:
Lower density, high pore volume, and a greater number of mesopores and macropores. This makes it less hard but highly effective for large molecules.
Decolorization: Ideal for removing color compounds from liquids, such as in the sugar and edible oil industries, as color molecules are typically large.
Air & Gas Purification: Used for specific gas-phase applications where larger contaminant molecules need to be adsorbed.
Pharmaceutical and Chemical Industries: Effective in processes that require the removal of high molecular weight organic compounds.
Frequently Asked Questions (FAQs)
What is Granular Activated Carbon used for?
Granular Activated Carbon (GAC) is widely used in drinking water treatment, gold recovery, solvent recovery, food & beverage purification, industrial water treatment, and air purification.
How is GAC different from Powdered Activated Carbon (PAC)?
GAC is used in continuous fixed-bed systems where water or air passes through it, while PAC is a fine powder typically dosed into liquids for batch treatment.
What are the main advantages of Coconut Shell-Based GAC?
Coconut shell GAC offers high hardness, high density, and predominantly microporous structure, making it ideal for removing small organic molecules and ensuring long service life.
Can Granular Activated Carbon be regenerated?
In many industrial applications, GAC can be thermally regenerated, allowing multiple cycles of use and lowering overall operating costs.
Which industries benefit most from GAC?
Industries such as municipal water treatment, food & beverage, pharmaceuticals, chemicals, mining (gold recovery), and air purification are among the largest users of GAC.
