A structured mathematical model has been developed to describe the formation and emission of odourous compounds in anaerobic sludge digestion. Special emphasis is given to the general mechanisms for the formation of four ubiquitous sulfur odorous compounds in anaerobic digesters: methyl mercaptan (MT), dimethyl sulfide (DMS), dimethyl disulfide (DMDS) and hydrogen sulfide (H2S), as well as to VFA and ammonia (NH3). The model includes multiple-reaction stoichiometry, microbial growth kinetics and conventional material balances for an ideally mixed reactor. A sensitivity analysis was performed to identify the most substantial model parameters that impact on odour emissions. Based on the sensitivity analysis a parameter set was identified that generated estimates of odourous compound concentrations that were typical of those reported in the literatures. In this regard, the impacts of temperature, SRT, solids loading and solids composition were assessed.
