Product Overview
WT-P is a high-activity coal-based granular activated carbon engineered for municipal, industrial, and laboratory wastewater treatment. Manufactured from select bituminous coal through carbonization and high-temperature steam activation, it delivers an iodine adsorption value exceeding 1000 mg/g with a specific surface area above 1000 m²/g.
The granular structure is optimized for fixed-bed operation in biological and physical wastewater treatment trains. With low moisture content, controlled ash, and high mechanical strength, WT-P withstands the demanding hydraulic conditions of sewage treatment— including backwashing, variable organic loading, and extended service cycles—while maintaining consistent adsorption performance for COD reduction and organic contaminant removal.

Key Application Areas
- Municipal Sewage Treatment — Polishes secondary effluent in municipal plants, adsorbing residual organics and micropollutants before discharge or reuse.
- Industrial Wastewater Processing — Treats effluent from chemical, pharmaceutical, and food manufacturing where variable organic loads require reliable adsorption capacity.
- Post-Biological Tertiary Treatment — Integrates after activated sludge or MBR systems to remove non-biodegradable organics, color bodies, and trace contaminants that biological processes cannot fully degrade.
- Reclaimed Water Production — Prepares treated wastewater for non-potable reuse applications by removing residual COD and organic precursors that could foul downstream membranes.
- Pre-Treatment & Stormwater Management — Protects downstream biological units from organic shock loads and treats variable-flow wastewater streams.
Key Advantages
- High Iodine for High-Load Duty: >1000 mg/g iodine and >1000 m²/g surface area deliver rapid adsorption kinetics for COD and organic removal in high-volume wastewater streams.
- Granular Durability for Harsh Service: >90% crush strength and low floating rate ensure stable bed performance through repeated backwashing and hydraulic stress.
- Coal-Based Cost Efficiency: Bituminous coal feedstock provides economic activated carbon for large-scale continuous wastewater operations without sacrificing adsorption capacity.
- Tertiary Treatment Versatility: Compatible with biological treatment trains, acting as a polishing step or shock-load buffer without disrupting microbial ecosystems.
