E3.02 Bonvin 2016 ReNUWIt Annual Meeting Poster

Little is known about the presence or fate in of odorous compounds in direct potable reuse (DPR) systems. This project aims to assess whether these low molecular weight compounds present a potential barrier to the implementation of DPR through a broad monitoring of full-scale conventional and advanced wastewater treatment systems and quantitative analysis of target odorants. Results indicate that the target compounds are detected in wastewater effluent at concentrations up to 100 x higher than their odor thresholds.

However, in advanced treatment systems, the compounds are reduced to acceptable levels. Still, future potable reuse systems should take into consideration the influent concentration of these compounds when designing the treatment train to ensure adequate removal.
