| Abstract This paper focuses on the evaluation of Al-Salamia water supply treatment plant was undertaken for the influent and effluent characteristics twice a week for the period from January 2004 till the end of December 2004 from low lift pump which represents river water sample; after sedimentation tanks; after filtration tanks and after adding chlorine, Physical and chemical measurements (nitrogen, PO4, turbidity, pH, Ec, Hardness and residual chlorine) were analyzed data to assess the performance of plant and the efficiency removal of turbidity. Nutrients (nitrogen, PO4) range between (0.065-0.19) (0.15-0.52) mg/l respectively, which support the algae growth and led to the blocking in intake. Ec, pH and hardness values are found to be (440-854)um/cm2 ,(7.7-8.6) and (185-303) mg/l respectively. pH values decrease after adding alum and chlorine and reaches 7.4 . The performance of the plant in terms of turbidity removal ranges from 60.58% to 42.86% when effluent turbidity ranges from (2.9 to 8.2) NTU. Paired T-test was used to attain the main objective of this study regarding the turbidity removal efficiency of each units . | ||
