| Περίληψη: | The membrane-aerated biofilm reactor (MABR) is naturally suitable for partial nitritation-anammox (PN/A) because aerobic and anaerobic microorganisms can grow in different biofilm layers. However, suppressing nitrite-oxidizing bacteria (NOB) in the oxygen-rich inner MABR biofilms remains challenging, while anammox bacteria (AnAOB) in the outer layer are more vulnerable to many harsh treatments. This study demonstrated the strategy of applying hydroxylamine (NH (Copyright © 2025. Published by Elsevier Ltd.) |
