Wastewater treatment configuration and operation influence the temporal variability of odour emissions from anaerobically digested biosolids.
Analysis using GC-SCD, TD-GC-MS, and sensory evaluation revealed higher concentrations and detection frequencies of key VSCs (DMDS, DMS, DMTS, MeSH) during Phase 1, often exceeding odour thresholds and challenging their beneficial reuse. Extended monitoring is advised to improve management practices and support sustainable land application.
