An odour Attribution Study to determine the relative contribution from three facilities for the development of real-time odour monitoring

le .

48 006a   An Odour Attribution Study is undertaken in North America for an Air Quality Management Agency that includes athering data from specific sources and ambient locations to better understand odour impacts within the local communities. Specifically, the following objectives were to be met:

  Identify odorant compounds impacting the area of concern via comprehensive quantitative and qualitative analyses; Determine the relative contribution and variability of the odorant compounds emitted from the three key source facilities; Develop a strategy for continuous real-time odorant monitoring to measure emissions impacting the community from the three key source facilities.

Navigating the complex landscape of biological odour control solutions for Waste Water applications

Webb   Biofiltration is not a one-size-fits-all technology. In order to properly design the biological odour control process, the foul air source needs to be accurately characterized. The optimal biological odour control configuration will depend strongly on the compounds contributing to odour. Considering the application of biological odour control to wastewater treatment plants specifically, this paper first describes the most common odorous compounds and how each can be biologically degraded.

   Several case studies demonstrate the importance of selecting the proper biological technology based on the foul air source. This paper is intended as a Manual of Best Practices for environmental professionals interested in applying the latest developments in advanced biological odour control techniques.

Comprehensive evaluation of granular activated carbon from a wastewater treatment plant deodorisation and regeneration system for subsequent reuse.

008   In this work, the physico-chemical, olfactometric and textural characterization of granular activated carbon (GAC) from the odor adsorbent beds of an urban wastewater treatment plant (WWTP), as well as the chromatographic quantification of the retained odoriferous compounds, were carried out.

   These techniques allowed an integral evaluation of such adsorbent material, which came from the deodorization at four stages of integral wastewater treatment (pretreatment header: GAC-1; sand and fat removal: GAC-2; sludge thickening: GAC-3; sludge dewatering: GAC-4).
