Summary: The recycling of water and nutrients is becoming an issue of high Australian and international priority. Membrane bioreactor (MBR) technology combines biological treatment and membrane filtration for solid/liquid separation. Traditional MBR has the drawbacks of partial removal of nutrients, high costs and a large footprint.We will develop a compact high-rate MBR coupled with a fluidized ion exchange system for complete pollutant removal and nutrient recovery. This will involve i) designing a compact system by coupling MBR with inert media which remove organic matter with less fouling and ii) developing efficient hybrid media for nutrient removal and recovery by ion exchange.
