Profiling and modelling of thermal changes in a large waste stabilisation pond

Abstract: A thermal profiling study was undertaken at four depths at each of nine sites, and at the inlets and outlets of a large waste stabilisation pond (WSP). Results were collected simultaneously using a network of 42 thermistors and dataloggers. Profiles at each site were categorised as either "stratified" or "unstratified", and persistence analysis was used to determine the frequency and persistence of stratification events at each of the nine sites. Stratification was found to persist most strongly at the site fu… Show more

“…The Bolivar WSPs are located north of Adelaide, South Australia (34845 0 23 00 S 138834 0 15 00 E) and comprise six ponds operating in two parallel trains covering a total area of around 350 ha; treating effluent from a population equivalent of 800,000 people. The first and largest pond (Pond 1) was selected for this research (see Sweeney et al (2005a) for detailed description). With a nominal operating depth of 1.3 m and an hydraulic residence time of 12 -15 days, the tertiary-level facultative WSP receives effluent from an AS plant.…”

“…Samples of sediment and overlying wastewater (5 L) were also collected using a tubular sediment corer (3 cm £ 130 cm) and transported to the laboratory. In the laboratory, samples (wastewater or wastewater plus sediment) were incubated in water bath acclimated microcosms under dark conditions at 258C-a temperature similar to that at the sample sites during summer (Herdianto 2003;Sweeney et al 2005a). Microcosm inorganic N concentrations were augmented either with 10 mg NO 2 -N L 21 or 100 mg NH 4 -N L 21 .…”

“…Computational fluid dynamics (CFD) modelling of hydrodynamic flows and the implementation of disinfection models to maturation ponds have been developing (Wood et 3 al., 1995(Wood et 3 al., , 1998Shilton and Harrison, 2003;Shilton and Mara, 2005;Sweeney et al, 2005;Abbas et al, 2006;Shilton et al, 2008;Badrot-Nico et al, 2009;Alvarado et al, 2012a,b;Dahl et al, 2017b) in parallel with the continual improvements to sunlight kinetic rate models (e.g.…”

“…Turbulent flow modelling of thermal energy was only undertaken by Dahl et al (2017b) for maturation ponds and by Sah et al (2011) for facultative ponds and possibly by Sweeney et al (2005) and Badrot-Nico et al (2009). Laminar flow models have been employed by Wood et al (1995) and Olukanni and Ducoste (2011).…”
