ELAWADYWater Pollution Control Department National Research Centre Dokki Cairo EgyptSummaryThe meat processing industry is believed to produce highly polluted wastewater Analysis of such wastewater indicated that the waste was highly contaminated with organic pounds as indicated by COD 1544 mgO2 l1 BOD 646 mgO2 l1 and TSS 1155 mg l1 Moreover oil and grease concentrations reached 144 mg l1 treatment of raw wastewater using Upflow Anaerobic Sludge Blanket UASB followed by Rotating Biological Contactors RBC was studied Efficiency of the UASB for the removal of CODtotal BODtotal TSS and oil and grease was 56 56 85 and 58 respectively The quality of the UASB effluent barely plies with the regulatory standards for discharging wastewater into the sewerage network UASB effluent was subjected for further treatment using a RBC unit to improve the quality of the treated effluent for reuse in irrigation purposes Residual COD BOD TSS and oil and grease following RBC was 132 mgO2 l140 mgO2 l1 44 mg l1 and 10 mg l1 respectively The overall efficiency of the treatment units provided good quality effluent The overall percentage removal of COD BOD TSS and oil and grease was 915 94 96 and 91 respectively Based on the quality of the treated effluent and guidelines remended for wastewater reuse it may be concluded that a slight to moderate restricted irrigation is applicable to reuse the treated effluent in the green belt around the factory Disinfection should be applied to ensure the safety of such a processIntroductionEnvironmental pollution is seriously increasing throughout the world because of economic growth and increased human activity Wastewater is one of the major pollution problems brought about bysuch development The enormous investment in wastewater treatment is increasing not only inprimary cost but also the endless running cost thatgenerates no economic prot Anaerobic wastewater treatment AnWT bined with properposttreatment represents the ideal solution forenvironmental protection Several advantages areassociated with the application of anaerobictreatment including 1 low energy requirement 2 little sludge produced and 3 production ofmethane gas as a source of energy Lettinga et al1992 Anaerobic treatment and a bination ofmechanical and physicalchemical methods areremended for wastewater pretreatment of food industry euent at high organic load VonHagel 1988 AnWT is effective in removing biodegradable organic pounds leaving someother organic substances and mineralized pounds in the treated effluents These pounds therefore have to be removed if necessary – by an additional posttreatment step to reach acceptable water quality levels for discharging wastewater into surface water or sewerage network The ability of uplow anaerobic
