Performance Assessment of Al Muamirah Wastewater Treatment Plant ‎‎“Using Statistical Analysis” at Hilla city, Iraq‎

Abstract

The evaluation was based on the plant operation data such as BOD₅, COD, TSS, T.N, PO₄, NH₃, SO₄, NO₃, Cl, and Oil&Grease for the period of 11months from Oct. (2020) to Aug. (2021). Data taken from a laboratory in the wastewater treatment plant and compiled in Excel software. The results showed that the efficiency of removal of BoD₅, COD, TSS, T.N, PO₄, NH₃, SO₄, NO₃, CL, and O&G was 92.68%,78.97%,94.27%,62.61%,81.83%,83.32%, 8.71%,61.53%,12.29%, and 88.88% respectively on a monthly basis. Accordinig, it can be recommended that the Al-Muamirah wastewater treatment plant has an acceptable efficiency except for the efficiency of sulfates and chlorides that are not acceptable please treat them in the future. A multivariate statistical technique of the data has been attempted by applying cluster analysis using a statistical (SPSS). Cluster analysis shows that months (December20, February21, October20, January21 and November20) indicate a good level of treatment compared to that of (March21, May21, August21, Jun21, July21 and April21).
