Product Overview
WT-S is a coal-based granular activated carbon designed for reliable performance in standard-duty wastewater treatment applications. Manufactured from bituminous coal through carbonization and steam activation, it provides an iodine adsorption value above 900 mg/g with a specific surface area exceeding 900 m²/g.
Engineered for fixed-bed operation in municipal and industrial sewage plants, WT-S balances adsorption capacity with cost efficiency. The granular form ensures low pressure drop and uniform flow distribution in pressure or gravity filters, while the high crush strength withstands the backwashing and hydraulic stresses typical of continuous wastewater service.

Key Application Areas
- Municipal Wastewater Polishing — Provides final organic removal in municipal treatment plants, ensuring effluent meets discharge or reuse standards.
- Industrial Effluent Treatment — Handles mixed industrial wastewater from manufacturing, processing, and utility operations where organic removal is required before discharge.
- Biological Post-Treatment — Serves as a tertiary adsorption stage following activated sludge, trickling filters, or MBR systems to capture residual COD and color.
- Water Reuse & Recycle — Prepares treated wastewater for industrial reuse by removing organics that could foul cooling towers, boilers, or irrigation systems.
- Pre-Treatment Protection — Acts as an organic buffer upstream of sensitive biological units, protecting biomass from toxic shock and variable loading.
Key Advantages
- Cost-Effective Tertiary Performance: >900 mg/g iodine delivers sufficient capacity for standard municipal and industrial wastewater polishing at a practical price point for large-volume consumers.
- Rugged Fixed-Bed Design: >90% crush strength and consistent granular geometry resist breakdown during backwashing, maintaining bed permeability and reducing fines carryover.
- Proven Coal Base Reliability: Bituminous coal activation provides predictable adsorption kinetics and stable supply for continuous wastewater operations.
- Operational Flexibility: Performs equally well in gravity filters, pressure vessels, and combined biological-physical treatment trains.
