Performance Evaluation of Al-Rustamiya Wastewater Treatment Plant

Al-Rustamiya sewage treatment plant (WWTP) serves the east side of Baghdad city (Rusafa) and is considered one largest projects.It consists three parts (old project F0, first extension F1, second F2) that treat wastewater effluent discharged into Diyala river thus Tigris River. These plants are designed constructed with an aim to manage reachIraqi standard for BOD5, COD, TSS chloride concentrations 40, 100, 60 600 mg/L respectively. The data recordedfrom March till December 2011 provided from Al-RustamiyaWWTP, were in this study evaluate performance plant. results indicated strength entering varied medium high. average within Iraqi standards. overall efficiency removalswere: For BOD5: 92.1, 90.31, 92.96% F2 respectively COD: 88.23, 87.9, 87.95% TSS: 86.98, 80.72, 89% Chloride: 14.79, 15.37, 15.31% mean value BOD5/COD ratio raw was 0.67 as typical untreated domestic wastes. BOD/COD ratios treated F0 0.48, F1 0.50 0.38. did not confirm indicating wastewaterneeds more
