Granular activated carbon (GAC) is one of the most widely used adsorption materials for liquid and gas purification. With a well-developed porous structure, high adsorption capacity, and excellent mechanical strength, GAC is designed for fixed-bed filtration systems that require long service life and stable performance.
Xingsen provides granular activated carbon solutions made from different raw materials, including coconut shell, coal, and nut shell. By adjusting pore structure, particle size and adsorption performance, our GAC products can meet various requirements in water treatment, air purification, food processing and industrial purification.
Understanding GAC Adsorption Performance
Granular activated carbon is produced by carbonizing and activating carbon-rich materials to create millions of microscopic pores.
Compared with powdered activated carbon (PAC), granular activated carbon has a larger particle size, better filtration performance, and lower pressure loss, making it suitable for continuous adsorption systems.
Main advantages:
Made from selected coconut shells, this type of GAC features highly developed micropores, high purity, and excellent adsorption performance.
Main advantages：
Recommended applications:
Coal-based GAC provides balanced pore distribution and strong adsorption performance, making it a cost-effective choice for large-scale industrial purification.
Main advantages:
Recommended applications:
Produced from nut shell materials, this carbon combines good adsorption performance with excellent hardness and abrasion resistance.
