Abstract
Turbidity is a visual property of water that expresses the amount of suspended substances in the water. Its presence in quantities more significant than the permissible limit makes the water undrinkable and reduces the effectiveness of disinfectants in treating pathogens. On this basis, turbidity is used as a basic indicator for measuring water quality. This study aims to evaluate the removal efficiency of AL- Muthanna WTP. Water turbidity was used as a basic parameter in the evaluation, using performance improvement evaluation and data from previous years (2016 to 2020). The average raw water turbidity was 26.7 NTU, with a minimum of 14 NTU, with a maximum of 48 NTU. Water turbidity value for 95% of settling daily reading data was (13.7) NTU which is larger than the goal value (10) NTU, which achieves (51.2) % of the optimum goal. In comparison, the water turbidity value for 95% of daily reading data of water filtered was (6.90) NTU which is larger than the goal value (5) NTU, which achieves (68.8) % of the optimum goal. The removal efficiency for previous years (2016 to 2020) was (78.5, 76, 73.5, 72, 68)%, respectively, within acceptable limits.

IntroductionWater is an essential component of life and an important factor in achieving human and economic development
As the international authority on public health and water quality, the World Health Organization promotes global efforts to prevent the spread of waterborne diseases, advises governments on developing health goals and systems, and develops drinking water treatment methods based on FAO's health performance standards
Samples were modeled during basic treatment methods, and this data was entered into the optimization assessment software (OAS), which is a program developed by the US Environmental Protection Agency that aims to examine the performance
Summary
Water is an essential component of life and an important factor in achieving human and economic development. The comprehensive performance evaluation is an integrated program that serves as an effective tool for understanding the operational problems and difficulties that drinking water treatment plants face, as well as knowing the efficiency of the work of the units of those plants based on the chemical, physical, and biological characteristics of raw and treated water to determine the quality of pollutants removed (Chang et al, 2007). Most developed countries have developed an integrated program for reviewing and evaluating drinking water plants in order to identify the problems and obstacles that prevent the achievement of economic feasibility and the goals that these stations were established on, as well as to provide appropriate solutions to advance the reality of the treatment process(Absar Ahmed Khan and M.Tech., 2018). The target of this research assessment is the performance removal efficiency of AL-Muthanna WTP based on turbidity as the main parameter
