“…MBR is, in fact, one of the most important innovations in wastewater treatment [ 1 , 2 , 3 , 4 ], as it overcomes the drawbacks of the conventional ASP, including large space requirement for secondary clarifiers, liquid–solid separation issues, production of excess sludge, and limitations with removal of recalcitrants [ 5 ]. MBRs have been used for both municipal and industrial wastewater treatment and reclamation [ 6 , 7 , 8 , 9 , 10 ]. An MBR is a hybrid of a conventional biological treatment system and physical liquid–solid separation using membrane filtration [ 11 , 12 , 13 ] in one system.…”

Membrane Bioreactor (MBR) Technology for Wastewater Treatment and Reclamation: Membrane Fouling

The membrane bioreactor (MBR) has emerged as an efficient compact technology for municipal and industrial wastewater treatment. The major drawback impeding wider application of MBRs is membrane fouling, which significantly reduces membrane performance and lifespan, resulting in a significant increase in maintenance and operating costs. Finding sustainable membrane fouling mitigation strategies in MBRs has been one of the main concerns over the last two decades. This paper provides an overview of membrane fouling and studies conducted to identify mitigating strategies for fouling in MBRs. Classes of foulants, including biofoulants, organic foulants and inorganic foulants, as well as factors influencing membrane fouling are outlined. Recent research attempts on fouling control, including addition of coagulants and adsorbents, combination of aerobic granulation with MBRs, introduction of granular materials with air scouring in the MBR tank, and quorum quenching are presented. The addition of coagulants and adsorbents shows a significant membrane fouling reduction, but further research is needed to establish optimum dosages of the various coagulants/adsorbents. Similarly, the integration of aerobic granulation with MBRs, which targets biofoulants and organic foulants, shows outstanding filtration performance and a significant reduction in fouling rate, as well as excellent nutrients removal. However, further research is needed on the enhancement of long-term granule integrity. Quorum quenching also offers a strong potential for fouling control, but pilot-scale testing is required to explore the feasibility of full-scale application.

“…Therefore, the UAnSFB should be designed and operated for TPH removal based on the HRT rather than the inlet concentration. The findings of the current study suggest that increasing the retention time in a bioreactor treating slowly biodegradable contaminants including TPH is a critical operational strategy for attaining an efficient biodegradation performance [28].Increasing HRT provides more time for hydrocarbon molecules to be in contact with the microorganisms and thus enhances the biodegradation level. At TPH loading below the critical rate, the rate of hydrocarbons diffused to the biomass (either as suspended or biofilm) would also be low and would lead to mass transfer limitations.…”

“…Other methods such as physicochemical and chemical methods as coagulation [3][4][5][6][7][8][9], dissolved air flotation [4], electrocoagulation [5,10] and advanced oxidation processes (AOP) [6,8,[10][11][12][13][14] have been employed. Advanced methods based on biological processes such as using membrane reactors [17,18], mixed anaerobic-aerobic processes [19] or anaerobic reactors have also been investigated [20].…”

Three samples of cosmetic wastewater from the production of soaps and shampoos were treated by the following processes: coagulation with sedimentation (C/S), coagulation with dissolved air flotation (C/DAF), and the Fenton process (FP). The COD values of raw wastewater samples were 13 160, 13 580 and 9410 mg O2/dm 3. The anionic surfactants were 3000, 4500 and 4000 mg/dm 3 , for samples 1, 2, and 3, respectively. All three processes were effective in highly polluted cosmetic wastewater treatment. The most effective process was coagulation. In the case of sample 1, application of FeCl3 at pH 6.0 resulted in 88.2% of COD removal and the application of aluminum based coagulants allowed for 80.1-85.3% COD removal. In the case of samples 2 and 3, the usage of Al 1019 and Al 3010 coagulants brought about a 91.6% and 82.6% decrease in COD values, respectively. C/DAF was found to be less effective than C/S. The best results with C/DAF were obtained using Al 3010 coagulant with wastewater recirculation the COD removal efficiency amounted to 82.3, 87.3 and 78.8, respectively. The lowest COD removal efficiency was observed for FP and it was equal to 64.0 and 72.7% for samples 2 and 3, respectively.
