Membrane aerated biofilm reactor (MABR) and shortcut nitrogen removal are two types of solutions to reduce energy consumption in wastewater treatment, with the former improving aeration efficiency latter reducing oxygen demand. However, integrating these solutions, i.e., achieving MABR, is challenging due difficulty suppressing nitrite-oxidizing bacteria (NOB). In this study, four MABRs were established demonstrate feasibility initiating, maintaining, restoring NOB suppression using low dissolved (DO) control, presence absence anammox bacteria, respectively. Long-term results revealed that strict DO (< 0.1 mg/L) MABR could initiate maintain stable for more than five months nitrite accumulation ratio above 90%, but it was unable re-suppress once they prevailed. Moreover, increased threshold level MABRs, still incapable restore deteriorated conjunction control. Mathematical modelling confirmed experimental further explored differences conventional biofilms biofilms. Simulation showed compared biofilms, regardless thickness or influent concentration. Kinetic mechanisms different proposed, suggesting difficult wash out developed innermost layer because high sludge wasting rate. summary, study systematically demonstrated challenges through both experiments mathematical modelling. These findings provide valuable insights into applications call studies developing effective strategies achieve energy-efficient configuration.

This study focused on the evaluation and characterisation of carrier colonisation a deammonification moving-bed biofilm reactor (dMBBR) at low carrier-inoculation ratio (≤5%v/v), applying multiple methodologies. The dMBBR (5 L working volume) was filled with Aqwise carriers (50%v/v filling ratio) fed synthetic feedstock. Carrier differentially tracked using grey colour for new white pre-colonised seed carriers. operated 190 days nitrogen loading 125–140 gN/m3/d. Multivariant heatmap analysis process parameters indicated stable performance from day 85 onwards albeit some occasional malfunctions occurred, NH4+ total removal rates amounting to 85% 61%, respectively. Biofilm development carriers, evaluated by bulk density measurements via pycnometry, proved be reliable, simple, non-destructive methodology. Anammox genus Candidatus Brocadia ammonia oxidising bacteria Nitrosomonas were well established in line theoretical empirical specific activity tests. multi-parameter provides broad insight into biomass may assist shortening start-up period dMBBRs.
