Activated sludge (AS) diffusion effectively removes hydrogen sulphide (H2S) odours from wastewater treatment plants. This method offers a cost-effective and practical alternative to traditional odour control systems, achieving 100% H2S removal.

Area of Science:

  • Environmental Engineering
  • Microbiology
  • Wastewater Treatment

Background:

  • Wastewater treatment plants emit odours, primarily hydrogen sulphide (H2S).
  • Microorganisms in wastewater can degrade sulphurous compounds.
  • Activated sludge (AS) presents an economical and practical odour control solution.

Purpose of the Study:

  • Evaluate activated sludge (AS) diffusion as a bioscrubber for H2S removal.
  • Assess H2S removal efficiency at various concentrations (25, 75, 150 ppmv).
  • Determine if H2S diffusion increases overall odour concentration.

Main Methods:

  • Pilot-scale trials using aeration tanks and clarifier reactors.
  • AS diffusion bioscrubber system implementation.
  • Olfactometry measurements for odour assessment.

Main Results:

  • Achieved 100% removal rates for hydrogen sulphide (H2S).
  • No significant increase in odour concentration detected via olfactometry.
  • Odour levels decreased during H2S dosing periods.

Conclusions:

  • Activated sludge (AS) diffusion is a highly effective bioscrubber for H2S odour removal.
  • This method is practical and cost-efficient for wastewater treatment plants.
  • AS diffusion does not increase overall odour levels.
