Specify the target contaminant, water conditions, flow rate and required particle size before selecting a coal-based or coconut shell grade.
Confirm the CIP, CIL or CIC circuit, particle size, gold adsorption requirements and resistance to attrition for the selected grade.
Identify the target gas, concentration, flow rate, temperature and humidity, and confirm whether a standard or impregnated grade is required.
Confirm the process medium, treatment objective and applicable compliance requirements. Match these to a documented grade and suitability test.
Granular activated carbon (GAC), also called granulated activated carbon or granular activated charcoal, is a porous adsorbent supplied as granules. It is produced from carbonaceous raw materials through carbonization, activation and screening. Material, particle size and surface treatment should be selected for the intended process.
For an impregnated grade, the impregnant and operating conditions must be matched to the target contaminant.
We specialize in steam-activated coconut shell-based granular activated carbon and coal-based granular activated carbon (bituminous coal and anthracite), supplied with different specifications.
Granular activated carbon is used in water treatment, gold recovery, air and gas treatment, and food and beverage processing. Each duty requires an appropriate grade and operating conditions. See the application guidance below, or view the additional granular activated carbon product information.
The published order report describes 12 tonnes of coal-based granular activated carbon supplied for water filters, with 25 kg branded bags and shipment to Cat Lai Port. The customer requested virgin carbon and attention to ash, strength and iron content.

This repeat order report describes 56 tonnes of coconut shell granular activated carbon in 6×12 mesh, shipped via Cotonou. The customer’s purchasing priorities included ash content and customised bags.
Read the Niger case →Sample orders can be requested for testing and evaluation. Product photographs, a TDS or an SGS report may also help you review the product before arranging a sample. Confirm which documents are available for the selected grade.
20 kg, 25 kg and 500 kg bags are listed among the packaging options. Custom packaging and customer branding can be discussed for the order.

Quality is our culture. We have a professional quality testing center that conducts chemical and physical tests on raw materials before production. We will control the quality of the goods during all the mass production. Please let us know immediately if you are not satisfied with Huamei's quality or service.
Pricing and order requirements depend on the selected grade, specification, quantity, packaging and delivery destination. Send these details with your inquiry so we can confirm the quotation and applicable minimum order quantity.
Coal-based and coconut shell GAC differ in raw material and pore characteristics. Compare documented grades against your target contaminant, operating conditions and test requirements rather than selecting by raw material or iodine value alone.
Choose particle size against the equipment design, required contact, pressure drop, flow or slurry conditions, and fines control. Confirm the sieve standard and size distribution before ordering.
Replacement depends on operating conditions and the required outlet performance. Monitor the relevant contaminant or process indicator and follow the agreed breakthrough or replacement criteria. There is no single service interval for every GAC system.
