Brief description Nitrogen Removal in Wastewater Treatment Using the Nitrite Pathway. 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.
