Multivariate statistically-based modelling of a membrane bioreactor for wastewater treatment using 2D fluorescence monitoring data

► Statistically-based models were developed for monitoring a membrane bioreactor. ► 2D fluorescence data was incorporated in addition to operation and analytic data. ► PLS modelling was applied, after PARAFAC compression of fluorescence data. ► Indicators of permeability, effluent quality and biomass were successfully modelled. ► Multiple performance descriptors can be simultaneously monitored with few analysis.
