Import Coal-Based Granualr Activated Carbon — Buy in Bulk from Supplier in China

Coal-based granular activated carbon from Wenxian Hongtai Water Treatment Materials Factory is produced from anthracite coal through physical activation, resulting in a hard, porous structure with high mechanical strength. The product is supplied in granules sized between 0.8mm and 4.0mm, with a typical iodine number ranging from 800 to 1000 mg/g and a BET surface area of 900 to 1200 m²/g, as measured by standard ASTM D3860 and ISO 10463 methods. The carbon exhibits low ash content, generally below 12%, and minimal moisture levels under 5%, making it suitable for continuous flow systems.

This material is engineered for industrial adsorption applications where structural integrity matters. The granule form resists attrition during handling and backwashing, unlike powdered forms. The pore structure is optimized for medium to large organic molecules, such as phenols, chlorinated hydrocarbons, and volatile organic compounds. These characteristics align with standard industry expectations for coal-based granular activated carbon, though exact values may vary by batch. The supplier does not specify the activation method, but steam activation is typical for this product type.

End users include municipal water treatment plants, chemical manufacturers, and industrial effluent processors requiring reliable contaminant removal. The product is commonly loaded into pressure vessels or fixed-bed filters. Packaging is typically in 25kg woven polypropylene bags with inner liners, though custom bulk packaging may be available. Trade terms such as FOB or CIF are likely offered, but confirmed terms must be requested directly. Minimum order quantities and lead times are not disclosed and require supplier confirmation.

Wenxian Hongtai Water Treatment Materials Factory is located in the Yuecun Industrial Zone, Jiaozuo, Henan Province, China. The supplier is categorized as an imported tier with harbor trust verification, indicating some level of trade documentation compliance. The listing does not disclose company history, workforce size, annual production volume, or client names. There is no information on certifications, laboratory testing capabilities, or export experience beyond the trust tier designation.

The supplier's focus appears to be on producing coal-based activated carbon for industrial filtration markets. No details are provided regarding research and development, in-house quality control protocols, or production capacity. The absence of response rate or average response time suggests limited communication channels. Buyers should treat this supplier as a manufacturer with basic export readiness, and verify all technical claims directly before placing orders.
