Two-phase anaerobic digestion of cheese whey was investigated in a system consisting of a stirred acidogenic reactor followed by a stirred methanogenic reactor, the latter being coupled to a membrane filtration system to enable removal of soluble effluent whilst retaining solids. The acidogenic reactor was operated at a hydraulic retention time (HRT) of one(More)
This study examined the practical performance of a cross-flow ultrafiltration membrane coupled to an anaerobic bioreactor, for treatment of raw domestic wastewater (RDW), at a pilot-scale plant. Wastewaters used in this study originated from two different domestic wastewater treatment plans (DWTPs) (Sfax and Ksour Essef). During the treatment in the(More)
An anaerobic membrane bioreactor (MBR) was operated for 367 days to treat domestic wastewater originating from the Sfax wastewater treatment plant. The results showed that the MBR was not very efficient because of the considerable fluctuations in the domestic wastewater composition and the presence of toxic compounds resulting from the industrial effluents(More)
The removal efficiencies of pathogens such as Salmonella (S), helminths ova (H), protozoan cysts (P), total coliforms (TC), faecal coliforms (FC) and faecal streptococci (FS) by three treatment processes: aerated lagoon (AL), activated sludge (AS) and anaerobic membrane bioreactor (MBR) were evaluated by means of standard microbiological numeration methods.(More)
The aim of this study was to compare the effect of industrial discharges on the anaerobic treatment of domestic wastewater in both laboratory and pilot-plant scales at mesophilic conditions. The laboratory experiment results have shown the low process efficiency of anaerobic treatment of DW by the use of an adapted or a non-adapted methanogenic inoculum.(More)
High rate anaerobic treatment systems such as anaerobic membrane bioreactors (AMBR) are less popular for slaughterhouse wastewater due to the presence of high fat oil and suspended matters in the effluent. This affects the performance and efficiency of the treatment system. In this work, AMBR has been tried for slaughterhouse wastewater treatment. After the(More)
