“…It was also observed the storage phenomenon, due to the ability of specific microorganisms to rapidly convert external substrate into internal storage products under dynamic conditions, as outlined in previous studies [37]. The obtained data from respirometry analysis may contribute to support modelling application for future studies [39,40].…”

“…They found that the salinity affects the amount of N 2 O emissions over the nitrification process. There was an agreement between the predictions and measurements . In another research investigation, Mannina et al developed a comprehensive integrated membrane bioreactor (MBR) model to simulate the main biological and physical processes involved in the wastewater treatment process, where the removal of phosphorus, nitrogen, organic matter, and greenhouse gases was targeted.…”

“…Membrane fouling leads to a decline in the permeate flux by reducing the membrane permeability, an increase in the trans‐membrane pressure (TMP), and, finally, a considerable reduction in the treatment performance . Prediction and modelling of membrane fouling have been the focus of numerous investigations . For instance, Mannina et al introduced a new mathematical model to determine the greenhouse gas emissions, including carbon dioxide and nitrous oxide, produced from membrane bioreactors (MBRs).…”

Current Status and Future Prospects of Membrane Bioreactors (MBRs) and Fouling Phenomena: A Systematic Review

et al. 2018

Membrane bioreactors (MBRs) have been widely used for municipal and industrial wastewater treatment around the world due to their advantages, which include higher efficiency, smaller footprint, and lower sludge production over other conventional activated sludge (CAS) processes. However, membrane fouling that results from physicochemical interactions between the membrane and the components of the mixed liquor still remains the most challenging matter preventing the broad application of MBR technology. Recently, a considerable number of experimental and modelling investigations have been conducted concerning MBRs and membrane fouling. Despite the development of low‐fouling membrane systems, more research and engineering activities with a focus on surface modification, wastewater specifications, pre‐treatment and treatment conditions, and efficient fouling control and remedy strategies are still needed to minimize the probability of the occurrence of fouling. It is vital to investigate important aspects of the characterization and mechanisms of the fouling phenomenon to find reliable and long‐term solutions. This review provides a detailed survey of the main aspects of the MBR processes, configurations, advantages and disadvantages, fouling phenomenon, and fouling control strategies in MBRs. Past research and engineering activities in this area are critically reviewed such that pros and cons of recent developments in fouling inhibition and mitigation approaches are also discussed. The main practical and theoretical challenges for the effective utilization of MBRs in various municipal and industrial sectors are then addressed. At the end, we offer useful practical guidelines and recommendations for the better design and operation of MBRs in industrial and public communities.
