This work focus to alleviate the fouling in Membrane bioreactor (MBR) by integrating electrooxidation,adsorptive cake, bio-film carriers and ozonation referred as Integrated Moving Bed Bioreactor (IMBBR). The total organic carbon (TOC), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS)removal were observed as above 95%, 95% and 70% at 300 kPa with theflux increase in 35%. The numericalmodel was developed which proved less fouling which was in agreement with Scanning electronmicroscopy (SEM) and Liquid Chromatography and Mass Spectroscopy (LCMS). This study showed lessenergy consumption without the problem offilamentous bulking.

The present study focuses on overcoming the drawback as fouling in a membrane bioreactor (MBR), which can be alleviated by integrating advanced oxidation process, adsorption, and biofilm carriers in the activated sludge process. The optimal sludge retention time, carbon and ozone dosage was 150 minutes, 15 g and 1.5 Lmin−1, respectively. The percentage removal was observed to be above 90% for chemical oxygen demand and total organic carbon whereas for total dissolved solids was only 40% under transmembrane pressure of 20 kPa. The increase in permeate flux was 30% as compared to MBR. Sequential batch membrane bioreactor (SBMBR) showed 12% reduction in energy consumption for three hour operation at the flow rate of 0.72 L/h (transmembrane pressure 20 kPa), and it was confirmed in the SEM of carbon, membrane, UV, CV and HPLC also. The energy consumption required also confirms the less internal fouling via the extended backwash of four hours.
