“…Critical flux (J c ) is a performance indicator quantifying the productivity of the membrane under operation [98]. The flux rate is relatively steady up to the critical flux rate and it has been said that within this stage of filtration, the fouling rate is negligible [40,99].…”

“…This is because of the high F/M ratio which invariably encourages sludge bulking and an increase in the viscosity [65,172]. The increase in viscosity is not suitable for hydraulic conductivity within mixed liquor because of the excessive drag resistance which may amount to a noticeable decrease in mass and oxygen transfer [98,169]. Therefore, more turbulent aeration with stronger forces may be required to overcome the hydraulic resistance and to ensure proper mixing of the activated sludge [172].…”

“…In a different study, solid retention time (SRT) pose a strong influence on the rate of biofilm formation as a result of the protracted polarization of biomass and persisting interaction on the membrane surface [204]. At a longer SRT, the soluble microbial product (SMP) concentration is high which easily got accumulated onto membrane pore walls to initiate blockage [98,[203][204][205]. In addition, longer retention of activated sludge encourages shifting of microorganism growing rate to endogenous phase and this may lower the F/M ratio.…”

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.

“…Membrane fouling rate depends on the properties of soluble microbial products (SMP), extracellular polymeric substances (EPS) and the organic loading rate (OLR) [44,45]. Increase of OLR results in increase of production of specific EPS and macromolecules in the SMP and EPS fractions which stimulate flocullation and finally fouling cake formation [46].…”

“…Increase of OLR results in increase of production of specific EPS and macromolecules in the SMP and EPS fractions which stimulate flocullation and finally fouling cake formation [46]. Moreover, since the EPS is usually more viscoelastic and hydrophobic at a higher OLR, adhesion of fouling to the membrane increases drastically when OLR is higher than 1.4g COD/l/d [44].…”

Brief review of operation of anaerobic wastewater treatment with membrane bioreactors

2019

View full text Add to dashboard Cite

In recent years, anaerobic membrane bioreactor (AnMBR) technology has been considered as a very appealing alternative for wastewater treatment due to its significant advantages over conventional anaerobic treatment and aerobic membrane bioreactor (MBR) technology. The paper provides an overview of the current status of the anaerobic membrane bioreactor technology with a special emphasis on its performance and drawbacks when applied for domestic and municipal wastewater treatment. According to the reported data, the renewable energy produced at the plants (i.e. from methane) covered the energy demand for membrane filtration while the excess energy can be further utilized. Anaerobic membrane bioreactors are an attractive technology that needs further research efforts and applications at an industrial scale.

Reuse Potential of Refinery Wastewater Treated Using a Two‐Stage Submerged Membrane Bioreactor

et al. 2022

Refinery wastewater treatment was performed using a novel submerged tubular ceramic membrane bioreactor (STMBR) with the oleaginous hydrocarbonoclastic bacterium Rhodococcus opacus. A membrane‐based flux study with the STMBR was carried out to assess the performance of the tubular ceramic membrane. Continuous experiments with the STMBR achieved a maximum chemical oxygen demand (COD) removal of 84 %, with an average flux of 0.4 × 10−3 m3m−2s−1. To further enhance the COD removal efficiency, two STMBR were operated under the optimum conditions. Complete COD removal along with 2.98 g L−1 biomass growth was achieved during two‐stage STMBR operation. Furthermore, a toxicity assessment of the permeate water established its reuse potential.
