Nitrogen removal via short-cut simultaneous nitrification and denitrification in an intermittently aerated moving bed membrane bioreactor

► An intermittently aerated MBMBR was investigated to achieve SND via nitrite. ► The intermittent-aeration strategy was an effective approach to achieve nitrition. ► The activities of NOBs were inhibited under the intermittently aerated mode. ► The intermittently aerated mode had no effect on the activities of AOBs.
