Novel nitrogen removal process via nitrite in a biofilm system and analysis of microbial community dynamics

点击翻译按钮获取中文摘要

Nitrogen removal from wastewater is essential to protect our unique aquatic environment. This removal is typically achieved via two steps: Nitrification converts ammonium via nitrite to nitrate; denitrification converts nitrate via nitrite again to harmless nitrogen gas. This project will develop a biofilm reactor system, which enables this process to run via nitrite only, instead of nitrate. Savings of 40% carbon and 25% oxygen requirements are possible this way. This process has not yet been demonstrated under controlled conditions, but recent progress in the research groups in Australia and Korea now offer novel ways to accomplish this promising process.
