Import Anthracite Filter Material — Buy in wholesale FOB from Supplier in China

Ningxia Biyuan Activated Carbon Co., Ltd. produces anthracite filter material intended for water and wastewater treatment systems, manufactured at its facility in Taisha Industrial Zone, Pingluo County, Ningxia. The product is described as a dual-layer composite of anthracite coal and quartz sand, designed to increase filtration surface area and capture efficiency. The company cites ISO and SGS certifications for quality assurance, though buyers should request current certificate copies directly. Packaging and exact granulometry are not specified in the source data and should be confirmed with the supplier.

Anthracite filter media in the water treatment industry typically exhibits effective size (D10) of 0.8 - 1.2 mm, uniformity coefficient (D60/D10) below 1.7, and specific gravity near 1.6 - 1.7, though these standard values may differ from Ningxia Biyuan's actual product. The combination with quartz sand, a conventional support medium with higher density and hardness, creates a stratified bed where larger anthracite particles remain on top while finer quartz settles below, extending filter run duration between backwashes. Mohs hardness for anthracite media typically ranges 3.0 - 3.5, versus 7.0 for quartz, affecting attrition rates and replacement scheduling.

Municipal water works, environmental engineering firms, and industrial wastewater plants are the principal consumers of this filter category. Applications include gravity and pressure rapid sand filters, multimedia filters for tertiary sewage treatment, and pre-treatment stages for reverse osmosis plants. The dual-layer configuration is particularly valued where turbidity spike tolerance and long filter runs are prioritised over absolute particle removal. Buyers should clarify MOQ, lead time from Pingluo to destination port, and whether the quoted Incoterms are FOB Tianjin or CIF, as Ningxia is landlocked and overland transport to a seaport adds cost and transit variables.

Ningxia Biyuan Activated Carbon Co., Ltd. operates from Taisha Industrial Zone in Pingluo County, Ningxia Hui Autonomous Region, postal code 753000. Ningxia is China's principal anthracite-producing region, with reserves and carbonisation expertise that support a cluster of activated carbon and filter media enterprises. The company holds a harbour trust tier on the platform, with zero recorded response rate and zero average response hours, indicating limited or unmeasured enquiry traffic rather than necessarily reflecting operational scale.

The supplier profile does not state founding year, employee count, annual turnover, installed production capacity, or named clientele. Its product line focuses on anthracite-based filtration media rather than activated carbon, despite the corporate name. Buyers should treat marketing claims about global reach export quality with standard due diligence, requesting business licence, ISO certificate registration numbers, and SGS audit reports for independent verification. The absence of disclosed MOQ or lead time means these must be negotiated directly.
