“…At lower temperature, the rate of particles and colloids gyration is low, thereby higher shearing force is required to scour the accumulated foulants on the membrane [70,216] and vice versa. Consequently, this could drastically increase the operating energy, and running cost [121,217]. present the best treatment performance, with 85% contaminants removal efficiency during the pretreatment [57].…”

“…The temperature process in MBR for POME treatment is mostly considered under two conditions: thermophilic and mesophilic [195,229]. Actually, the temperature has a direct effect on the viscosity of mixed liquor which could significantly influence the overall mass transportation [213,217]. This implies that high permeate volume is more visible under thermophilic condition because of the lesser hydraulic resistance [195].…”

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.
