Gimenez Garcia, J.B. Ozgun, H. Tao, Y. Van Lier, J.B. Faculty Civil Engineering and Geosciences Department Water Management Date 2013-06-25 Abstract A laboratory scale external anaerobic dynamic membrane bioreactor (AnDMBR) treating high strength wastewater was operated to assess the effect of gas sparging velocity and organic loading rate on removal efficiency and dynamic membrane (DM) filtration characteristics. An increase in gas sparging velocity (GSV) results in a decrease in DM filtration resistance. DM or cake formation was identified as the main contribution to the total filtration resistance. Over 99% COD removal was obtained in the study regardless of the GSV. The results showed that the DM formation process proceeded until a stable cake layer thickness was reached. An effective pollutant removal and high permeate quality was obtained by the effective dynamic membrane layer formation at OLRs between 2-3.6 kg COD/m3.d. The investment and operational costs are expected to be substantially lower than the conventional membrane filtration.
