Nitrogen Removal in Wastewater Treatment Using the Nitrite Pathway (2002–2004)

Abstract:
Nitrogen removal from our wastewater is becoming very important in most parts of Australia to protect our unique aquatic environment. This removal is achieved biologically through two steps: Nitrification converts ammonium via nitrite to nitrate; and denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project aims to develop a method that allows this process to go just via nitrite, instead of nitrate, to nitrogen gas. This would significantly reduce oxygen and/or carbon requirement in nitrogen removal. If successful, the new operating method will allow modern wastewater treatment plants to achieve a better effluent quality at lower costs.''
