Abstract:

MABR exhibits excellent TN removal performance for treating ROC with low C/N ratio.

Operating conditions should be properly controlled to achieve optimal TN removal.

Denitrifying bacteria and NOB are proved notably inhibited by high salinity stress.

The TN removal rate remains over 70% when the NaCl addition amount is below 20 g/L.
