SEMINAR: Seminar - Wastewater treatment, disposal and non-potable reuse via aquifer infiltration
|Seminar - Wastewater treatment, disposal and non-potable reuse via aquifer infiltration : Dr Mike Donn, 2 August, 4pm
Treated wastewater (TWW) is infiltrated into aquifers via infiltration ponds for disposal and non-potable reuse at many wastewater treatment plants across WA. Infiltration, a form of Managed Aquifer Recharge (MAR), provides water quality improvement of TWW associated with natural processes during infiltration and within the aquifer. A collaborative research project between the CSIRO and Water Corporation analysed decades of historical groundwater and TWW quality data using a probabilistic modelling approach to evaluate TWW contaminant removal efficiency via aquifer treatment.
The analysis of TWW infiltration sites with long-term operational data will be presented providing evidence that with appropriate wastewater treatment, recharge volume and aquifer characteristics, contaminants may be substantially attenuated via aquifers.
Dr Mike Donn is a Research Scientist with CSIRO. Since joining CSIRO in 2006 his research has been focused on understanding biogeochemical transformations in shallow groundwater systems in urban and peri-urban settings. His current research interests lie in the application of environmental chemistry to understanding the impacts of using treated wastewater for Managed Aquifer Recharge, in particular the natural attenuation in shallow groundwater and the potential benefits for non-potable reuse and the environment.
Debbie Reed and Arron Lethorn from the Water Corporation will also be available for questions
