Abstract

The research includes a study of analyzing and evaluating the reliability of turbidity removal and the amount of residual chlorine in the water in the Rashidiya water center located in Rashidiya-Baghdad-Iraq according to the permissible criteria for making decisions based on solid scientific foundations. Thus, water treatment centers in general need a reliable evaluation that helps in evaluating the output Water treatment centers according to the standards set for each center. The research aims to evaluate the reliability of the Rashidiya water center using the two-parameter Weibull distribution, where the distribution parameters were estimated using the least squares method using the (Matlab 2022) program. The chi-square test was used for Goodness of Fit at a significant level of 0.05, through the Easy Fit 5.5 professional program. It was found to be distributed according to the Weibull distribution, and descriptive statistics were calculated for each parameter, and it was found that the mean (and median) of the turbidity values (9.379), which is within the permissible limit, The mean (and median) chlorine values are (0.0279), which is also much less than the permissible limit. The efficiency scale was used to remove turbidity. It was found that the average efficiency of turbidity removal is 71.35%, which is a relatively acceptable level. However, it is necessary to increase the turbidity treatment to raise the level of efficiency. It was found through the Weibull distribution analysis that the value of reliability for the removal of turbidity is (0.99), and for the remaining amount of chlorine is (0.99). The research concluded that the Rashidiya water center is reliable during the research period. The research recommends evaluating all water treatment centers in Iraq in general, and in Baghdad in particular, periodically and at certain time periods. The research also recommends using the natural logarithm distribution as it is suitable for evaluation.

基于Weibull分布的巴格达al- rashidiyah地区底格里斯河水处理中心可靠性分析

该研究包括根据基于坚实科学基础的决策允许标准，分析和评估位于伊拉克巴格达拉希迪亚的拉希迪亚供水中心的除浊可靠性和水中余氯量。因此，水处理中心通常需要一个可靠的评估，以帮助根据为每个中心设定的标准评估水处理中心的产量。该研究旨在使用双参数威布尔分布来评估拉希迪亚水中心的可靠性，其中分布参数是使用（Matlab 2022）程序使用最小二乘法估计的。通过Easy Fit 5.5专业程序，卡方检验用于拟合良好性，显著水平为0.05。结果表明，其分布符合威布尔分布，并对每个参数进行描述性统计，发现浊度值的平均值（和中值）（9.379）在允许范围内，氯的平均值和中值为（0.0279），也远低于允许范围。采用效率标度法去除浊度。结果表明，平均除浊率为71.35%，是一个相对可接受的水平。然而，有必要增加浊度处理以提高效率水平。通过威布尔分布分析发现，除浊的可靠度值为（0.99），余氯的可靠性值为（099）。研究得出结论，拉西迪亚水中心在研究期间是可靠的。该研究建议对伊拉克的所有水处理中心，特别是巴格达的水处理中心进行定期和特定时间段的评估。研究还建议使用自然对数分布，因为它适合评估。
