A diverse range of volatile organic compounds (VOCs) are emitted from wastewater biosolids processing. Odorous emissions are predominately made up of volatile sulfur compounds (VSCs) which are typically the only odorants measured. However, a range of VOCs are known to contribute to malodours yet previous studies often overlook the contribution of VOCs in comparison with VSCs.

Highlights

  • This review covers aspects from both analytical odour sampling as well as a community assessment paradigms.
  • The dose-response relationship is discussed as a complex system that has varying degrees of influence dependent upon the olfactory quality assessed.
  • Combined approaches are discussed and are found to be advantageous compared to single type methodologies.

GC–MS/O methodologies are broadened to improve ecological validity.
A Community Odour Wheel for untrained individuals is implemented.
A combined online and workshop based community engagement structure is proposed.
Common language between all stakeholders in environmental malodour provides many advantages.

Odorous emissions from wastewater biosolids processing can cause nuisance impacts to the surrounding community. Odour Wheels are an effective tool for environmental odour management, but have yet to be provided for wastewater biosolids processing. Emissions throughout the biosolids processing from eight wastewater treatment plants, each with different unit operation configurations, were surveyed to identify odorants present and their olfactory properties. Chemical and olfactory methods identified a range of odorants and odours emitted throughout biosolids processing.

Volatile sulfur compounds (VSCs) are important contributors to nuisance odours from the processing of wastewater sludge and biosolids. However, emission characteristics are difficult to predict as they vary between sites and are likely to be affected by biosolids processing configuration and operation.
