AWMC Seminar Program: Purple phototrophic bacteria for simultaneous organics, nitrogen and phosphorous removal from domestic and industrial wastewater

Purple phototrophic bacteria for simultaneous organics, nitrogen and phosphorous removal from domestic and industrial wastewater - A summary by Tim Hülsen.

Abstract: Mixed culture purple phototrophic bacteria (PPB) have recently been proposed as an alternative platform for wastewater treatment utilising photoheterotrophic growth. The concept is based on non-destructive assimilation and accumulation of organics (COD), nitrogen (NH4-N) and phosphorous (PO4-P) whereby resources are preserved in the biomass, rather than dissipated e.g. into the atmosphere. This presentation will summarise the work on domestic wastewater of the last 3.5 years, including the first batch tests, the continuous reactor operation at ambient and low temperatures (10 °C) and the overall feasibility of the Partition-Release-recovery concept. Furthermore, the expansion of the PPB technology to industrial wastewaters with focus on the recovery of high value products such as single cell protein and the impact on the overall feasibility will be discussed.
