odour management refereed paper technical features 64 NOVEMBER 2012 water objectionable and most organoleptically potent compounds such as VOSCs and organic nitrogen compounds have been depleted. It would also be advantageous to determine whether these odours are considered objectionable or not, and at what concentrations do the odours become acceptable. While studies conducted in this project utilised sludge and biosolids samples from just one WWTP, future studies will expand the scope to include biosolids and sludge sourced from other WWTPs. This would provide information on odorous compounds in biosolids produced at other WWTPs and determine whether the trialled odour reduction strategies are applicable to more than one type of wastewater treatment system.
