“…The presence of soluble microbial products (SMPs) has been recognized as one of the main factors leading to membrane fouling [ 58 ]. In order to improve the understanding and the representation of the individual foulants, starting with the late 1980s, mathematical models have been developed to include the contribution of the SMPs into the MBR bioprocesses either individually [ 59 , 60 ] or as an extension of the ASMs [ 61 , 62 , 63 ].…”

“…These new representations enhance the performance of the ASMs in the modelling of the biomass kinetics inside the MBR without the need for calibration with experimental data. However, the addition of SMP components and other variables generally results in complex models with many variables which can make their validation difficult due to over-parameterization [ 58 ].…”

The membrane bioreactor (MBR) is an efficient technology for the treatment of municipal and industrial wastewater for the last two decades. It is a single stage process with smaller footprints and a higher removal efficiency of organic compounds compared with the conventional activated sludge process. However, the major drawback of the MBR is membrane biofouling which decreases the life span of the membrane and automatically increases the operational cost. This review is exploring different anti-biofouling techniques of the state-of-the-art, i.e., quorum quenching (QQ) and model-based approaches. The former is a relatively recent strategy used to mitigate biofouling. It disrupts the cell-to-cell communication of bacteria responsible for biofouling in the sludge. For example, the two strains of bacteria Rhodococcus sp. BH4 and Pseudomonas putida are very effective in the disruption of quorum sensing (QS). Thus, they are recognized as useful QQ bacteria. Furthermore, the model-based anti-fouling strategies are also very promising in preventing biofouling at very early stages of initialization. Nevertheless, biofouling is an extremely complex phenomenon and the influence of various parameters whether physical or biological on its development is not completely understood. Advancing digital technologies, combined with novel Big Data analytics and optimization techniques offer great opportunities for creating intelligent systems that can effectively address the challenges of MBR biofouling.

“…Process modeling in membrane systems is based on membrane filtration. The focus of modeling is on the physical processes that occur after filtration, such as concentration polarization and membrane fouling (Hamedi et al 2021). Membrane filtration models are mostly realized in a mechanistic way using Darcy's law and the concept of series resistance.…”

In this study, a laboratory-scale microfiltration membrane system was operated with olive oil industry wastewater (OMW) and cheese whey effluent (CWE) with chemical oxygen demand (COD) concentrations of 54 and 65.6 g/L at flow rates (Q) of 100, 150, and 200 L/h, pressures of 1 and 2 bar, filtration times considered as four different hydraulic retention time (q) of 30, 60, 90, and 120 min, respectively. COD removal efficiencies decreased with decreasing q from 120 min to 30 min and increasing pressure. In this study, mathematical models such as first-order kinetics, Grau second-order, and Modified Stover-Kincannon models were applied to determine the organic matter removal kinetics of the microfiltration membrane system. The model’s kinetic parameters were determined by linear regression using the experimental data. The predicted effluent COD concentrations were calculated using the kinetic constants. Grau second-order and Modified Stover-Kincannon models were found to be more consistent with the observed data. Moreover, the correlation coefficient (R2) obtained for the experimental and predicted effluent COD concentration also confirmed the suitability of the kinetic models and showed that the models can be used in the kinetics of organic matter removal in microfiltration membrane system design, thus predicting the behavior of the membrane for treating olive oil industry wastewater and cheese whey effluent. The experimental results obtained in this study are expected to be used as a reference for the determination of organic matter removal kinetics in membrane systems.

“…Kinetic information on specific growth rates, lag phases, biomass yields, and substrate consumption rates under different environmental conditions helps construct mathematical models that optimize and predict bioprocess outcomes [ 5 ]. In the food industry, selection of appropriate models depends on the characteristics of the microorganism and the food matrix, and their accuracy should be validated with experimental data [ 6 , 7 ].…”
