“…The efforts devoted by the researchers have yielded some improvements such as membrane fouling control strategies and filtration. However, the level of achievement is still under development and economically unsustainable for industrial application [243][244][245], particularly in the oil palm processing.…”

Over the years, different types of alternative technologies have been developed and used for palm oil mill effluent (POME) treatment. Specifically, membrane bioreactor (MBR) has been employed to relegate pollutants contained in POME under different operating conditions, and the technology was found to be promising. The major challenge impeding the wider application of this technology is membrane fouling, which usually attracts high operating energy and running cost. In this regard, novel methods of mitigating membrane fouling through the treatment processes have been developed. Therefore, this review article specifically focuses on the recent treatment processes of POME using MBR, with particular emphasis on innovative processes conditions such as aerobic, anaerobic, and hybrid processing as well as their performance in relation to fouling minimization. Furthermore, the effects of sonication and thermophilic and mesophilic conditions on membrane blockage were critically reviewed. The types of foulants and fouling mechanism as influenced by different operating conditions were also analyzed censoriously.

“…Another advantage of AnMBRs is high biomass retention, operation at relatively short HRT and a smaller footprint [13][14]. Moreover, long SRT enhances the degradation of particulate and colloidal organics, reduces biosolid production and improves effluent water quality [15][16].…”

Domestic and industrial wastewaters are characterized by high organic content along with other diverse pollutants. Modern wastewater management comprises efficient removal of pollutants and gain energy to fulfil the discharge standards, protect the environment and sustain economic development. Until the last few decades, aerobic treatment technologies were dominant in wastewater treatment. Despite efficient treatment, large energy consumption for aeration, high operational cost and production of a great amount of sludge are the main drawbacks of aerobic systems. Wastewater treatment by anaerobic biological processes has many advantages over aerobic and other removal systems [1]. In addition to higher organic matter removal with less nutrient requirement, lower sludge production and energy-rich methane (CH 4) production are the main outcomes of anaerobic technologies. Various individual and combined anaerobic reactor systems have been successfully applied for the treatment of wastewater [2-5]. Anaerobic bioreactors contain a diverse microbial community, and slow-growing methanogens are very sensitive to changes in environmental conditions. In order to achieve the high treatment performance

“…Membrane fouling results in the reduction of membrane permeability during filtration and, consequently, an increase in its resistance to flux . In this case, membrane cleaning would be necessary in order to restore membrane permeability, although this might decrease the lifespan of the membrane, leading to more frequent membrane replacement costs …”

“…They also concluded that shorter SRT/HRT results in higher heterotrophic biomass activity . Important factors in choosing biocarriers include specific surface area, porosity, and density to promote biofilm attachment and growth, non‐toxicity, and chemical and mechanical stability . It was reported that adding biocarriers to MBRs leads to an increase in membrane filtration and alleviate membrane fouling because of improving mixed liquor properties, decreasing biopolymers concentration, and providing a strong mechanical scouring effect on the membrane surface …”

“…[44,45] In this case, membrane cleaning would be necessary in order to restore membrane permeability, although this might decrease the lifespan of the membrane, leading to more frequent membrane replacement costs. [15,46,47] The operational expenditures of MBRs are augmented due to control strategies associated with fouling such as air scouring, backwashing, implementation of the cross-flow velocity (CFV), and utilization of chemicals for membrane cleaning. Obviously, the fouling event affects capital expenditures as new membranes need to be purchased in order to replace damaged membranes.…”

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.
