Product Overview

WT is a coal-based granular activated carbon manufactured from select bituminous coal through carbonization and high-temperature steam activation. Available in WT 830 and WT 1240 configurations, it delivers an iodine adsorption value exceeding 800 mg/g with a specific surface area above 800 m²/g.

Engineered for municipal, industrial, and laboratory wastewater treatment, WT provides reliable organic removal and COD reduction in fixed-bed pressure or gravity filters. The granular structure ensures low pressure drop and uniform flow distribution, while the high mechanical strength withstands the backwashing and hydraulic stresses typical of continuous sewage service.

Key Application Areas

  • Municipal Sewage Treatment — Provides primary and secondary effluent polishing in municipal plants, adsorbing residual organics and improving effluent quality before discharge or reuse.
  • Industrial Wastewater Processing — Treats effluent from manufacturing, chemical, and food processing facilities where variable organic loads require consistent adsorption performance.
  • Post-Biological Tertiary Treatment — Integrates after activated sludge or biological reactors to remove non-biodegradable organics 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.
  • Wastewater Pre-Treatment — Protects downstream biological units from organic shock loads and treats high-strength influent before primary clarification.

Key Advantages

  • Proven Municipal Performance: Iodine >800 mg/g and surface area >800 m²/g deliver reliable COD and organic removal for standard-duty wastewater treatment.
  • Rugged Fixed-Bed Design: >90% crush strength and low floating rate maintain stable bed geometry through repeated backwashing and hydraulic surges.
  • Cost-Effective Coal Base: Bituminous coal feedstock ensures economical pricing for large-scale continuous wastewater operations without sacrificing adsorption consistency.
  • Dual Mesh Flexibility: WT 830 (1.4–1.7 mm) suits high-flow systems with lower pressure drop; WT 1240 (1.2–1.4 mm) enhances contact efficiency for tighter effluent requirements.

  • Q
    What is the difference between WT, WT-P, and WT-S?
    A

    WT delivers >800 mg/g iodine for standard municipal and industrial wastewater duty. WT-P offers >1000 mg/g for enhanced capacity in high-load or high-purity applications. WT-S provides >900 mg/g as a mid-tier alternative.

  • Q
    Is WT suitable for drinking water treatment?
    A

    WT is optimized for wastewater effluent. For drinking water, use GAC, PSD-A0, or LAC series with appropriate certifications.

  • Q
    Can WT be used in biological activated carbon (BAC) systems?
    A

    Yes. WT can be operated as a BAC medium where biofilm growth on the carbon surface enhances total organic removal through combined biological degradation and adsorption.

  • Q
    What is the typical service life in municipal wastewater?
    A

    Under normal secondary effluent conditions, expect 12–24 months before breakthrough. Higher industrial loads or poor biological pretreatment may shorten this interval.
