“…In another report, the application of nanofiltration (NF) membrane under suitable aeration for POME decolourization has been proved promising [153]. However, the most serious drawback of this treatment process is the outrageous TMP required to conduct the filtrate through the pores [184]. As substantiated earlier, membrane filtration at high TMP exposed the membrane to more expeditious fouling [185], due to the prohibitive foulants polarization towards the membrane surface [4].…”

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.

“…The operation of the membrane can be sensitive to changes in feed temperature [33][34][35]. This fact was checked in this study, with an average increase of 45.7% between 20 and 35˚C and 76.7% between 15 and 35˚C.…”

A B S T R A C TEffects of temperature on the permeate flux and the permeability of the membrane have been studied in a membrane bioreactor system with a moving bed pilot plant to treat real urban wastewater. In the present study, the permeability of the membrane has been determined under four different suspended solids concentrations and three different degrees of fouling in order to compare the effects of the temperature in different operational conditions. The permeate flux, critical flux and permeability of the membrane at seven different temperatures between 10 and 35˚C have been checked. The study showed that the permeate flux increased to 19.2 and 21.2% between 10 and 15˚C and between 15 and 20˚C respectively, which was higher than the 8.70% obtained between 20 and 25˚C, and similarly it increased to 15.6 and 15.6% obtained between 25 and 30˚C and between 30 and 35˚C, respectively. This trend has been also observed in critical flux values, under the different conditions of suspended solids and fouling degree tested. The data obtained on the permeability of the membrane was fitted to a multiple linear regression using dynamic viscosity and temperature as independent variables.

“…It should be noted, that all tests were marked by a decrease in the permeability of membranes. The use of semi-permeable membranes, with respect to the washing water is difficult because solutions contain substances that negatively affect the process of separating the emulsion [6,8,10] Filtering. Filtration is the most common method of cleaning contaminated washing water.…”
