For professionals involved in water treatment, selecting the right activated carbon is a science in itself. Among the most effective options is coal granular activated carbon (GAC), valued for its robust performance in purifying water. As a leading manufacturer and supplier, understanding the critical specifications of GAC is key to making informed purchasing decisions. This guide aims to equip R&D scientists and procurement managers with the knowledge to select GAC that precisely meets their water treatment needs.

Several parameters define the quality and efficacy of GAC. The Iodine Adsorption Value (IAV) is a primary indicator of the carbon's ability to adsorb small organic molecules. A higher IAV, typically in the range of 600-1100 mg/g for our coal GAC, signifies a greater capacity for removing a broad spectrum of contaminants. This is crucial for applications requiring the removal of taste and odor compounds, as well as certain organic pollutants.

Equally important is the Specific Surface Area (SSA). Measured in square meters per gram (m²/g), SSA reflects the total internal surface available for adsorption. Our coal GAC typically offers an SSA of around 950 m²/g, providing ample sites for contaminants to bind to. A larger SSA generally correlates with higher adsorption efficiency, making it a vital specification for achieving desired water purity levels.

Other critical specifications include particle size (e.g., 4-8 mesh, 6-12 mesh), which influences flow rates and contact time in filtration systems, and strength (typically >96%), indicating the carbon's resistance to crushing and attrition, which is vital for longevity in fixed-bed applications. Parameters like moisture content (typically <5%) and ash content (typically 6-10%) also play a role in the overall performance and purity of the GAC.
