Findings reveal effective aeration control optimizes nitrogen removal in hybrid MBBR-MBR systems, indicating promising strategies for wastewater treatment.
Key Points
This study aims to evaluate the stability of Partial Nitritation-Anammox in different reactor configurations and the role of aeration in optimizing performance.
Compared Sequencing Batch Reactor (SBR) with two Membrane Bioreactor (MBR) configurations.
Evaluated the effectiveness of an intermittently aerated MBR (MBR-I) in controlling Nitrite-Oxidizing Bacteria (NOB).
Assessed nitrogen removal rates and biofilm development under varied aeration conditions.
SBR demonstrated superior NOB washout compared to MBR configurations.
MBR-I achieved a total nitrogen removal rate (TNRR) of 76.38%, indicating effective NOB suppression through tailored aeration.
Aeration control was crucial in optimizing competitive kinetics for nitrite, enhancing overall system stability.
