Summary of Project
This project will establish the effectiveness of denitrification bioreactors as an on-farm technology for removing dissolved inorganic nitrogen (DIN) in waters draining the Babinda Swamp Drainage Area. The region has been identified as a hotspot for DIN in the Great Barrier Reef catchment. This will be the first trial of denitrification bioreactors in the Wet Tropics. Denitrifying bioreactors route water through a high-carbon substrate under anaerobic conditions to encourage denitrification (the conversion of DIN to atmospheric N2). Two bioreactor configurations will be tested at two sites, and the potential for broader adoption will be assessed.
