Abstract

Membrane Bioreactor Technology (MBR) can be used as a one-stage process for treatment of various kinds of wastewater which produces good effluents for reuse. In this research using MBR for oily wastewater has been investigated. A tubular micro filtration membrane was used for separating and recycling biomass, suspension, and heavy molecules which leave the bioreactor. The temperature was maintained between 34-36 Cº and COD ranges 500-2000 mg/L. The removal efficiency was between 93-97 percent, and MLSS concentration in bioreactor gradually increased to 16.2 g/L.
