Abstract/Summary The Elanora Wastewater Treatment Plant (WWTP) experiences ongoing odour issues related to highly septic influent. The UQ Sewer Model was built and applied to each of the three trunk rising mains serviced by the WWTP. Full scale chemical dosing trials were then completed for the largest of the three mains, using locations and dosing rates predicted by the model, for magnesium hydroxide (MHL), ferric chloride and oxygen injection. The field data and model results from the trials were then used to validate the model, so it could be applied to the remaining two trunk mains, to provide an optimal chemical dosing strategy for odour control at the Elanora WWTP. The model dosing rates were then assessed based on dissolved sulfide and total odour reduction, cost and availability of the chemical, safety of the dosing operation, and impact on WWTP performance. A permanent chemical dosing strategy using MHL has been proposed based on its safer operation, positive impact on the WWTP and more effective long-term odour control within the network and at the WWTP.
