SUSTAINABLE WASTEWATER TREATMENT TECHNOLOGIES: DEVELOPING AND ADAPTING LOW-COST ALTERNATIVE WASTEWATER TREATMENT TECHNOLOGY FOR SUSTAINABLE AMMONIA REMOVAL FROM WASTEWATER
Budget
R768 735.00

Nitrogen compounds, particularly in the form of ammonia, constitute a major fraction of the polluting organics in domestic and industrial wastewater streams which may cause serious environmental problems including eutrophication. Removal of nitrogen from high ammonia constituent influent wastewater streams is a major challenge for treatment plants worldwide. Anammox process represents a cost effective and environmental-friendly technology for ammonia removal from wastewater, and is currently being applied for biological nitrogen removal in different parts of the world including China, Netherlands and USA. The Anammox process may present a viable alternative to the conventional process due to its comparatively lower costs, energy and waste footprints.

 

In South Africa, though initiative was taken by different research groups to develop Anammox reactors, it has never been successful due to the lack of successful Anammox culture enrichment and appropriate technology transfer. The proposed project thus aims at devising a suitable Anammox reactor and optimization for long-term stable operation to provide an alternate bioprocess technology for the treatment of nitrogen/ammonium-rich wastewater. The proposed study will be conducted in collaboration with the Earth and Environmental engineering department, Columbia University, USA. Preliminary studies on the enrichment of Anammox bacteria have been initiated at the institute in 2015 using a seed culture obtained from Columbia University, USA. A bench scale continuous stirred reactor was designed and constructed to selectively enrich Anammox bacteria.
