الملخص

The aim of this work is to determine the potential use of sewage wasted sludge (SWS) as a source for heterogeneous microorganisms to be used in dairy wastewater treatment by anaerobic suspended digestion process. A lab scale stainless steel reactor was designed with dimensions of 600 mm height and 350 mm inner diameter. Different operating conditions of the treatment process were studied such as the organic loading rate (OLR), temperature and hydraulic retention time (HRT). For 14 days operation period, the results of the anaerobic digestion were expressed in terms of COD, BOD, TDS and TSS reduction. The effect of temperature was investigated by operating the reactor at temperature range of 20-40°C and the optimum reduction has been observed at 35 oC. The maximum removal efficiency was obtained at an OLR of 0.5 kg/m3.day and 72 hr HRT, at which COD, BOD, TDS and TDS were removed by 80%, 88%, 90% and 93% respectively. Keywords: Sewage Wasted sludge (SWS), Heterogeneous microorganisms, Anaerobic digestion Dairy wastewater.
