“…Irrespective of the process treatments, the MBR is usually utilized in two types of configurations; the submerged (sub-) and side-stream (ss-) configuration [31,76,[108][109][110], as depicted in Figure 3a,b, respectively. Basically, submerge configuration consist of immersion of the membrane module(s) inside the reactor and this allows direct interaction with activated sludge, while the side-stream configuration has its membrane placed outside the reactor and usually, it requires adequate cross flow velocity because of the need for recycling of activated sludge [111,112].…”

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.

“…From an operational point of view, ceramic membranes are a more suitable option for AnMBRs than polymer membranes. Under anaerobic conditions, membrane fouling tends to be more pronounced than in aerobic MBRs [24]; meaning that more concentrated chemicals, higher temperatures and/or longer exposure is required in order to recover membrane permeability. Since ceramic membranes have outstanding chemical and thermal stability, as well as increased resistance to corrosion and abrasion [3], they can be cleaned more effectively compared to polymer membranes [25].…”

“…Since ceramic membranes have outstanding chemical and thermal stability, as well as increased resistance to corrosion and abrasion [3], they can be cleaned more effectively compared to polymer membranes [25]. Although metallic membranes exhibit higher hydraulic performance, easier permeability recovery after fouling, improved stability, greater tolerance to oxidation and high temperatures than polymer membranes, they are expensive, hence used only in specific applications [3,24].…”

Anaerobic membrane bioreactors (AnMBRs) are increasingly being used in industrial wastewater treatment as the technology represents a cost-effective alternative to that based on aerobic processes. Not only AnMBRs are highly efficient in reducing chemical oxygen demand but the organic matter removed is transformed into a useful energy source-biogas. AnMBRs produce effluent that is free of solids and pathogens and rich in nutrients, while occupying a small footprint. As the membrane retains biomass, AnMBRs enhance performance when dealing with inhibitory or toxic substrates, typical of industrial wastewaters. Some drawbacks remain, however, including membrane fouling and its associated effects as well as poor efficiency at lower temperature (AnMBRs are usually operated at mesophilic or thermophilic conditions). Further research is needed on lowering hydraulic retention time, removal of nutrients, removal of specific micro-pollutants, establishing quantitative mass and energy/economic balances and inclusion of efficient dissolved methane recovery. In this mini review, the applications, limitations and perspectives of AnMBRs are summarized and evaluated with an emphasis on industrial wastewater treatment. Moreover, the AnMBR is compared with other wastewater treatment technologies presently available.

“…As a result, these Industrial effluents should be efficiently treated to protect the environment, aquatic life and humans from intoxication. In addition, due to continuing increase in water shortages and environmental protection concerns, industrial effluent treatment for reuse in the process has been accepted as a sustainable option to address these problems [3].…”

This paper presents a review of the previous laboratory analysis and case studies on the application of the pressure-driven ceramic membrane technology for treatment of industrial wastewaters. Ceramic membranes has attracted remarkable interests in recent decades for industrial wastewater treatment because of their superior characteristic such as high fluxes , reliable working lifetime under aggressive operating conditions and ease of cleaning. The literature review revealed that the efficiency of this technology has been proven in a wide variety of wastewaters from different industries and activities including pulp and paper, textile, pharmaceutical, petrochemical, food and mining. However, there are still challenges and questions for this technology that need to be addressed in future researches such as investment cost optimisation by introducing new fabrication technologies, selectivity, permeability and packing densities improvement, fouling minimisation and proposing scale up based on experimental research results.
