Water-washed activated carbon is processed through a water-washing treatment to reduce ash and inorganic impurities remaining from activated carbon production.
The washing process improves the cleanliness of the carbon and can reduce impurities that may interfere with adsorption or contribute to secondary contamination. Its performance depends on the carbon substrate, pore structure, and final product specification.
Water washing is a treatment process, not a guarantee of higher adsorption capacity. The final ash content, iodine value, and other specifications should be evaluated together when selecting a product.
Coconut Shell Water-washed Granular Activated Carbon is produced from coconut shells through carbonization, activation, and water washing. The washing step reduces ash and water-soluble inorganic impurities remaining after activation, making the carbon suitable for applications where cleaner granular media and lower impurity release are required.
Its coconut shell structure provides a relatively well-developed micropore system, which is useful for adsorbing smaller molecules and dissolved contaminants. Compared with coal-based carbon, coconut shell carbon is often selected when the process requires high adsorption performance, lower ash content, or a cleaner carbon medium.
The water-washed grade is available in several particle sizes for different contactors and filtration systems. It can be selected according to the target contaminant, required iodine value, ash limit, flow conditions, and replacement frequency.

Coal-Based Water-Washed Granular Activated Carbon is manufactured from selected anthracite coal and processed through activation and water washing. The washing treatment helps remove part of the ash and water-soluble impurities associated with the carbon production process, providing a cleaner granular medium for industrial treatment systems.
Its coal-based pore structure contains a broader range of pore sizes, allowing it to adsorb a wider range of organic contaminants in many industrial applications. The relatively dense structure and good mechanical strength make it suitable for fixed-bed systems that require stable particle performance during continuous operation.
This product is a practical option for industrial water treatment, wastewater polishing, and selected gas treatment processes where the system requires a balance between adsorption performance, mechanical strength, particle size, and operating cost. The final grade should be selected according to the target contaminant and the system’s ash and iodine-value requirements.
| Parameter | Specification |
| Raw material | Anthracite coal |
| Mesh size | 4×8, 8×30, 8×16, 12×40, 30×60, 80×150 |
| Iodine value | 700–1700 mg/g |
| Hardness | 95–98% |
| Bulk density | 0.45–0.55 g/cm³ |
| Ash | 2–4% |
| Moisture | ≤5% |
| pH | 8–11 |
Choose coconut shell water-washed activated carbon when you need low ash content, cleaner carbon, and high adsorption performance. Choose coal-based water-washed activated carbon when the system requires a dense granular medium with a broader pore-size distribution and stable performance in industrial treatment.
Base the final selection on the target contaminant, particle size, ash limit, iodine value, bulk density, and operating conditions—not the carbon base alone.
Select by Ash Content, Carbon Base and Particle Size
Water-washed activated carbon should be selected according to the required ash content, carbon substrate, particle size, and adsorption performance.
For applications with strict impurity requirements, the final ash content and other relevant specifications should be confirmed before product selection.
