As the principal objective, this present study compares the purifying performances of the membrane bioreactor (MBR) with the conventional activated sludge used from the wastewater treatment plant of Beni Messous (Algiers) with the average characteristics in the chemical oxygen demand being 586 mg/L and 188 mg/L in the biochemical oxygen demand and 14 NTU of turbidity. The membrane bioreactor re...

This paper proposes a methodology for managing complex sewerage networks based on the concomitant use of two performance evaluation methods, namely, failure modes, effects, and criticality analysis (FMECA) analytical hierarchy process (AHP). The FMECA is used to determine risks structural failures making it possible establish these failures. AHP check relationship consistency between indicators...
