Role of Mesh Pore Size in Dynamic Membrane Bioreactors.

ABSTRACT: Two identical bench-scale Self-Forming Dynamic Membrane BioReactors (SFD MBR) were set-up and operated for the treatment of real urban wastewater. The two bioreactors were equipped with meshes of different mesh pore size. Meshes having pore size values of 20 and 50 µm were tested under solid retention time (SRT) of 15 d, whereas meshes with 50 and 100 µm pore sizes were compared under SRT of 50 d. The results of long-term experiments showed very good overall performances by all systems at the steady state. High flux (in the range 61-71 L m-2 h-1) and very good effluent quality were obtained, with average suspended solids and chemical oxygen demanding values below 10 mg L-1 and 35 mg L-1, respectively. The mesh pore size did not have a major influence on the average cleaning frequency. Howe
