Waste Treatment Plant Odor Control Biofilter

The BIO Series Odor Control Biofilter is specially designed for waste transfer stations, landfills and incineration plants, featuring “multi-strain biofilm+multi-layer filtration” technology to remove H₂S, NH₃, VOCs with ≥96% efficiency. Complies with EU Landfill Directive 1999/31/EC and US EPA Subpart WW standards.

Application

✔ Transfer Stations: Waste compaction area emissions ✔ Landfills: LFG & leachate treatment plant exhaust ✔ Incinerators: Waste bunker & tipping hall odor control ✔ Organic Waste: Fermentation process gas treatment

Working Princple

  1. Gas Collection

  • FRP ducting with corrosion-resistant centrifugal fans

  1. Biofiltration Core

  • 4-stage treatment:

    • Pre-treatment: Water scrubber + humidity control (RH≥95%)

    • Stage 1: Sulfur-oxidizing bacteria for H₂S removal(>95%)

    • Stage 2: Nitrifying bacteria for NH₃ removal(>90%)

    • Stage 3: Mixed culture for VOCs degradation

  1. Smart Control

  • Real-time H₂S/NH₃ monitoring with automatic spray adjustment

  1. Final Emission

  • Odor concentration ≤1000, meeting strictest regulations

Features

  1. 🔸 High Efficiency
  • Specialized microbial consortia handle H₂S≤200ppm

  1. 🔸 Shock Resistance
  • Adapts to fluctuating concentrations (50-5000mg/m³)

  1. 🔸 IoT Monitoring
  • Remote access to operational data via web platform

  1. 🔸 Cost-effective
  • PP+FRP construction with ≥10 years service life
