Assessing the influence of climate change on water treatment Efficiency in Baghdad, Iraq

Predictions for the future indicate that climate change may worsen the water problem in Iraq. The impact of climate change on water supplies, the environment, and the economy, particularly theagricultural sector, is one of the region's most significant challenges. This paper analyzes the impact of climate change on water parametersand the implications for station operation and performance. The data was taken from the Al-Al-Qadisiyawater treatment plant in Baghdad city for 2022. This research is the onlyone that discusses the design of water treatment plants using the GPS-X to design and simulate the plants and show the effect of climate change on plant operation. The results of evaluating the operational performance of water treatment plants indicate that the concentrations of all contaminants in the effluent water have consistently followed the established Iraqi standards in all scenarios. Some consequences of these variables (pH, turbidity,TDS, color, alkalinity, and hardness).The modeling and simulation of the water treatment plant, conducted using GPS-X, confirmed an acceptable level of performance characterized by a high degree of efficiency. The model was subjected to three scenarios, which showed that the concentrations of the pollutant parameters in the treated water stayed within the allowed limits.
