Application of ultrasound to control and enhance performance of dynamic membrane in anaerobic
bioreactor

The concept of Dynamic Membrane (DM) where the fouling layer itself is used as the retaining medium could be used as the
possible solution for countering the problems encountered in membrane bioreactor processes. Anaerobic DM gives high
filtration resistance even at moderate flux within a short period of time. In this study, a novel concept of using ultrasound to
control and enhance dynamic membrane performance was studied. Two reactors with an ultrasound probe in the center of one
reactor were run simultaneously. The concept of steady Flux Decay Ratio (FDR) and analytical methods like extracted Extra
Polymeric Substance (EPS), soluble microbial product analysis, Scanning Electron Microscopy (SEM), Fourier Transform
Infrared (FTIR), Particle Size Distribution (PSD), Dehydrogenate Activity (DHA), Specific Methanogenic Activity (SMA)
and Chemical Oxygen Demand (COD) analysis were used in this study. Lower filtration resistance (20×10-10 m-1 ), increased
flux (10-12 L/m2h), lesser blocking degree of 62% FDR, more stickier and compact dynamic membrane layers, enhanced
microbiological activity and COD removal (95%) were observed. All results indicated that the dynamic membrane formed
with ultrasound application was less severely blocked more compact, microbiologically active and efficient compare to without
ultrasound
