Abstract: | Summary This study is carried out to propose an appropriate treatment technology for wastewater discharged from a flavor production
factory. Industrial wastewater discharged from this factory ranges between 50–70 m3/d with an average value of 60 m3/d. The major source of pollution in this factory is due to cleaning of the vessels therefore the treatment has been carried
out on the end-of pipe wastewater. The wastewater is characterized by high values of COD, BOD, TSS and Oil and grease 4646,
2298, 1790 and 626 mg/l respectively. Primary sedimentation of the wastewater for four hours reduced the COD, BOD, TSS and
Oil and grease by 43, 47, 80 and 74%, respectively. For the treatment of the produced wastewater, the biological treatment
process such as activated sludge, rotating biological contactor (RBC), up-flow anaerobic sludge bed reactor (UASB) have been
selected. The results from each treatment process proved to be efficient for the treatment of such wastewater. The treated
wastewater characteristics are in compliance with the Egyptian law which regulates the discharge of industrial wastewater
to the sewerage system. The RBC was selected and installed by the factory as it has the advantage of low operating and maintenance
costs. The factory RBC performance was monitored; characteristics of the treated effluent in terms of oil and grease, COD,
BOD and TSS were 27, 362, 139 and 95 mg/l, respectively. |
