About the research project

Australia has the sixth-longest coastline of any nation, with more than 85% of the population living within 50 km of the sea. Urbanisation, resource-extraction activities, and the need for greater agricultural outputs have already put significant pressure on our water supply, and impacts associated with climate change are beginning to emerge. As highlighted in a 2015 senate enquiry, Australia's urban area produces 3000 gigalitres of stormwater runoff annually. Contamination of coastal areas, water storages and oceans by polluted agriculture and stormwater runoff is a serious concern in Australia and worldwide. Declining coastal water quality, influenced by agricultural runoff, is recognised as one of the most significant threats to the Great Barrier Reef.

Constructed wetlands (CWs) are recognised as resilient, economical, and extensive decentralised eco-friendly technologies capable of meeting water treatment challenges. Until now electricity generation in Constructed Wetlands (CWs) integrated with Microbial Fuel Cell (MFC) for coastal areas is very low. The improvement in electricity generation or electron flow to the conductive material can be applied for real time applications such as pollutant sensing. In addition, transfer of electron to conductive material can also enhance the treatment of wastewater in CW.  It is reported by several studies with bioelectrochemical cells such as MFC, a large fraction of electron transfers to the methanogenic bacteria for the production of methane gas. This is the reason why the production rate of methane gas is high in CW-MFC systems whereas electricity generation is low. In this project, we are trying to inhibit methanogenic bacteria so that the entire or maximum electron goes directly to the conductive material. With extracting more electrons from the microbes, electricity generation of CW-MFC can be enhanced. This strategy can also be beneficial for producing greenhouse gases of low potential.

So, the objectives of this PhD research are:

  1. Enhance the electricity generation in MFCs by inhibiting the methanogenic activities
  2. Investigating the potential of MFC for real time applications such as pollution sensing
