Import Coal Columnar Activated Carbon — Buy in wholesale FOB from Supplier in China

Coal Columnar Activated Carbon from Ningxia Huiheng Activated Carbon Sales Co., Ltd. is a cylindrical form of activated carbon derived from bituminous coal, designed for liquid and gas phase adsorption. The product features a hardness rating above 90% and a bulk density of approximately 0.45 to 0.55 g/cm³, with particle sizes typically ranging from 0.8 mm to 4.0 mm. Its surface area exceeds 1000 m²/g, supporting strong adsorption of organic contaminants and chlorine compounds. This form is preferred over granular or powdered types in fixed-bed systems due to its low pressure drop and mechanical stability.

The carbon is manufactured through physical activation with steam or CO₂, resulting in a microporous structure optimized for adsorbing molecules under 1 nm in diameter. Standard iodine number values range from 800 to 1000 mg/g, and methylene blue adsorption typically exceeds 180 mg/g. The ash content remains below 10%, and moisture content is controlled under 5% to ensure consistent performance in wet environments. These specifications align with common industry benchmarks for coal-based columnar carbon used in water purification and solvent recovery.

This product is primarily purchased by municipal water treatment plants, chemical manufacturers, and industrial air filtration systems requiring sustained adsorption without frequent media replacement. Buyers typically order in 25 kg bags, 500 kg drums, or bulk container loads. Trade terms commonly include FOB Ningxia port or CIF destination, with lead times of 15 to 25 days after order confirmation. Packaging is polyethylene-lined with kraft paper outer layers to prevent dusting and moisture ingress during transit.

Ningxia Huiheng Activated Carbon Sales Co., Ltd. operates from Huinong District in Ningxia, China, with a facility focused on coal-based activated carbon production and export. The company is listed as a harbor-tier supplier, indicating verified manufacturing capability and export experience. Its profile confirms active engagement in international trade but provides no details on production capacity, workforce size, or years in operation. The supplier does not publish certifications, client lists, or laboratory test reports publicly.

The listing does not confirm ISO, SGS, or other third-party certifications despite claims in the source description. No evidence of in-house testing equipment or quality control protocols is available. The supplier's response rate and average response time are recorded as zero, suggesting limited or no real-time communication capability. Buyers should treat this as a manufacturer-to-exporter model with no direct customer service infrastructure.
