  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Trace organics removal using three membrane bioreactor configurations: MBR, IFAS-MBR and MBMBR

    Seventeen pharmaceutically active compounds and 22 other trace organic pollutants were analysed regularly in the influent and permeate from a semi-real plant treating municipal wastewater. The plant was operated during 29 months with different configurations which basically differed in the type of biomass present in the system. These processes were the integrated fixed-film activated sludge ...

  • Advanced treatment of Membrane Bioreactor (MBR) effluents for effective wastewater reclamation

    One of the two main objectives of this work is to oxidize MBR effluents with ozone/peroxide in high pH conditions in order to improve oxidation of pharmaceuticals, which could efficiently be rejected by the nanofiltration (NF) stage. The other main objective is to effectively oxidize of dissolved organic carbon (DOC) in MBR effluents in order to decrease fouling in the filtration stage. In this ...

  • Low dissolved oxygen membrane bioreactor processes (LDO–MBRs): a review

    Aeration energy demands for bioprocesses and membrane scouring in membrane bioreactors (MBRs) account for 50% to over 70% of the total operational energy consumption. Energy saving achieved by operating MBRs under low dissolved oxygen (DO) would be an interesting approach to bring MBRs to higher levels of efficiency. This review paper is first carried out to provide a systematic investigation on ...

  • Application of sequencing batch membrane bioreactors (SB-MBR) for the treatment of municipal wastewater

    Sequencing batch membrane bioreactors can be a good option in up-grading small municipal plant and for industrial applications, maintaining some of the advantages of both original technologies (effluent quality improvement, flexibility and simplicity of realization, operation and control). In this study, the effects of volumetric exchange ratio (VER) and aeration/filtration strategy have been ...

  • Fouling potentials of polysaccharides in membrane bioreactors (MBRs) assessed by lectin affinity chromatography

    In this study, the fouling potentials of polysaccharides contained in mixed liquor suspension in a membrane bioreactor (MBR) treating municipal wastewater were investigated using lectin affinity chromatography. This investigation was carried out with different membranes to assess the effects of membrane materials on fouling potentials of polysaccharides. In lectin affinity chromatography, some ...

  • Effects of FeCl3 addition on the operation of a staged anaerobic fluidized membrane bioreactor (SAF-MBR)

    The effects on sulfur removal and membrane fouling resulting from FeCl3 addition to an anaerobic fluidized membrane bioreactor (AFMBR) in a staged AFMBR (SAF-MBR) was investigated. Total sulfur removal in the SAF-MBR was 42–59% without FeCl3 addition, but increased to 87–95% with FeCl3 addition. Sulfide removal in the AFMBR increased to 90% with addition of FeCl3 at ...
