چکیده مقاله:
Background & Aims of the Study: Drinking polluted water can transmit diseases, so potablewater treatment is one of the most challenging and complex systems in countries. Continuousmonitoring for evaluation process in water treatment plant is important. This study aims toinvestigate performance evaluation of Qom water treatment plant to remove turbidity andcoliform in 2005 - 2014.Materials and Methods: In this cross-sectional descriptive study, daily results of experimentsfor coliform and turbidity parameters were collected in 2005 to 2014. Testing method is reportedaccording to standard method. Statistical approaches were done using SPSS. Moreover, resultsof output water tests were compared with Iranian National standards.Results: Range of turbidity level in raw water is observed from 1.05-253 NTU. Output turbidityvalues were less than the standard in all days. The annual average of turbidity and MPN in rawwater for ten years were 7.495 NTU and 19.06 respectively. Maximum annual average ofturbidity was between 2005 and 2006. Output turbidity values were less than Iranian Nationalstandard in all days.Conclusions: Performance of Qom water treatment plant to remove turbidity and coliforms fromwater corresponds with Iranian National Standard. Because of desert climate of Qom and alsoprobable creating flood conditions in some seasons, creating fluctuations in incoming water tothe plant is possible, that shows the importance of preparedness treatment processes to deal withsuch critical situations. Studies in field of evaluation water treatment can improve performanceprocesses and possible errors in treatment units.
