“…This is also in accordance to the work of Yin et al [125]: they confirmed that as the TMP varied to 300 psi, the permeate flux increased from 39 to 59 L/m 2 h. However, the major defects attributed to these operating conditions were the excessive energy demand (12 kW/m 3 ) for aeration and the lofty fouling susceptibility [121]. Equally, studies conducted by Le-Clech et al [108], Morrow et al [113], Xiao et al [126], and Abdurahman et al [127] reported comparable results, as presented in Table 2. Notes: EDP = energy demand for permeate, EDA = energy demand for aeration, NA = not available.…”

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.

“…Besides, at relatively low pH of the wastewater and recovery solution (Supporting Information, Fig. S1 ), the primary species of humic acid and bicarbonate are in molecular forms with neutral charge 40 , thus their migration competing with nutrient ions might be relatively weak. Further research on real wastewater is needed to investigate the dynamic balance between concentrated NH 4 + and PO 4 3− and other types of ions in the recovery solution during the long-term operation.…”

Conventional wastewater purification technologies consume large amounts of energy, while the abundant chemical energy and nutrient resources contained in sewage are wasted in such treatment processes. A microbial nutrient recovery cell (MNRC) has been developed to take advantage of the energy contained in wastewater, in order to simultaneously purify wastewater and recover nutrient ions. When wastewater was circulated between the anode and cathode chambers of the MNRC, the organics (COD) were removed by bacteria while ammonium and phosphate (NH4+-N and PO43−-P) were recovered by the electrical field that was produced using in situ energy in the wastewater without additional energy input. The removal efficiencies from wastewater were >82% for COD, >96% for NH4+-N, and >64% for PO43−-P in all the operational cycles. Simultaneously, the concentrations of NH4+ and PO43− in the recovery chamber increased to more than 1.5 and 2.2 times, respectively, compared with the initial concentrations in wastewater. The MNRC provides proof-of-concept as a sustainable, self-driven approach to efficient wastewater purification and nutrient recovery in a comprehensive bioelectrochemical system.
