Summary
Membrane Bioreactors have gained a considerable attention in the recent years for treating industrial wastes with an extensive advancement in the membrane technology. A Crossflow Membrane Bioreactor (CF-MBR) is one of the modifications to the conventional activated sludge process. It is the combination of a membrane module and an aeration tank containing the Mixed Liquor Suspended Solids (MLSS) that gives frequent benefits over the conventional wastewater treatment process. However, the biokinetics and performance of different operating parameters associated with this process are required to better design this type of treatment plant and to meet the effluent standards. The major objective of this study is to investigate the kinetics and the performance of crossflow membrane bioreactor for treating oily wastewater at two different MLSS concentrations (5000 and 3000 mg/l). The performance was measured based on the hydraulic efficiency (variation of flux, hydraulic retention time and transmembrane pressure) as well as the COD removal efficiency of the system. Several organic (BOD, TOC, oil & grease, phenol and ammonia) and microbial (heterotrophic plate count) parameters to evaluate the permeate water quality were measured throughout the study period. The effect of HRT on the system performance and the cleaning mechanism of the ceramic membrane were also investigated. (Abstract shortened by UMI.)
