Analysis and evaluation of performance of Al-Rustumiya wastewater treatment plant.

Wastewater treatment plants (WWTPs) are functional systems with several treatment procedures to mitigate pollutants and toxins in wastewater. The monitoring of the influent raw wastewater and the effluent processed wastewater has been conducted throughout the years 2022 and 2023 to assess the performance of the wastewater treatment plant. The chosen metrics for assessing the operational effectiveness of the Al-Rustumiya WWTP in Iraq are Biochemical Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Suspended Solids (TSS), Nitrate (NO3), Phosphorus (PO4), and the quantitative measurement of acidity or alkalinity (pH). The calculation and comparison of the removal effectiveness of each parameter in the influent and effluent wastewater are conducted concerning the Iraqi standards. The findings from the operational performance evaluation conducted on the Al-Rutumiya Wastewater Treatment Plant (WWTP) indicated that the quantities of all pollutants present in the effluent wastewater were found to comply with the established requirements set by the Iraqi regulatory authorities. The study revealed that the mean monthly levels of the parameters BOD, COD, TSS, and PO4 over 2022 and 2023 were determined to be 21 ppm, 44 ppm, 25 ppm, and 2.8 ppm, respectively. The parameters' concentrations adhere to the Iraqi Quality Standards (IQS) 2017. Furthermore, the removal efficiencies of biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), and phosphate (PO4) were found to be 91%, 83.4%, 96%, and 34%, correspondingly. The removal efficiency values of biochemical oxygen demand (BOD), chemical oxygen demand (COD), and total suspended solids (TSS) can be deemed satisfactory. [ABSTRACT FROM AUTHOR]
