Abstract

The principle aim of the research was to find methods of improving the efficiency and performance of the Nanango wastewater treatment plant with a particular focus on the secondary treatment process and replacing the aerators.

The research into the Nanango wastewater treatment plant has shown that it has been in operation in its current configuration since 1984 with no upgrades to the system or treatment process. In recent years the aeration process had been shown a decline in performance with the aerators themselves breaking down on a regular bases.

Research into wastewater treatment processes and theories, was used to compare the process in operation at the NWWTP. The data and information supplied from the NTP was used to identify possible methods of improving the current treatment
process efficiency and quality of effluent.

The research will show that the NWWTP problems or operational issues that it have been experiences with the secondary treatment process and aerators may not be due to the age of the aeration equipment. A lack of process control, system monitoring and testing would make it wrong to assume that these processes and operation were the contributing factors to the problems experienced at the NTP.

The recommendations of this project will hopefully help the South Burnett Regional Council make the choice to study the NWWTP process in order to gain a better understand of what is happening within the system before spending capital on new equipment.
