“…This shows that overall, the physical variables were within acceptable limits. Ayoub and El-Morsy [26] found an excellent WWQI rating for physical variables because of sufficient dilution by the hydraulic load; these findings were in line with the findings in this study. For the chemical variables, NH 3 and COD scored a very bad water quality rating; this can be attributed to the heavy organic load coupled with the inefficient removal of organic matter during treatment.…”

“…The Weighted Arithmetic Water Quality Index, adapted from Ayoub and El-Morsy [26], was used in this study to calculate the overall wastewater quality index (WWQI). We chose this index because it was easy to compute, and it incorporated all the water quality variables used in this study, and because it gave a single value that specifically described the state of each variable.…”

“…For the chemical variables, NH 3 and COD scored a very bad water quality rating; this can be attributed to the heavy organic load coupled with the inefficient removal of organic matter during treatment. A high sewage concentration, according to Ayoub and El-Morsy [26], profusely enhances NH 3 and COD levels; this results in effluents with unmanageable NH 3 and COD levels. On the other hand, NO 3 − and −PO 4 −3 scored an excellent overall WWQI rating.…”

Rivers in Africa have experienced dire pollution as a result of the poor management of wastewater effluent emanating from water resource recovery facilities (WRRFs). An integrated wastewater resource recovery model was developed and applied to identify ideal wastewater resource recovery technologies that can be used to recover valuable resources from a mixture of wastewater effluents in a case study in the Burgersfort WRRF in the Limpopo province, South Africa. This novel model incorporates the process of biological nutrient removal (BNR) with an extension of conventional methods of resource recovery applicable to wastewater. The assessment of results of effluent quality from 2016 to 2022 revealed that ammonia, chemical oxygen demand, total coliform, fecal coliform, and Escherichia coli levels were critically non-compliant with the permissible effluent guidelines, indicating a stable upward trend in terms of concentrations, and scored a very bad wastewater quality index rating. All variables assessed showed a significant loading, except for orthophosphates, and significant correlations were observed among the variables. The results of the integrated wastewater resource recovery model revealed a high probability of reclaiming recoverable resources such as nutrients, sludge, bioplastics, biofuel, metals, and water from wastewater, which have economic, environmental, and social benefits, thereby improving the effluent quality of a WRRF.

“…Therefore, the CCME WQI has been widely applied to many surface and groundwater bodies in Iraq [20,21] and other countries [22][23][24][25][26][27]. Recently, the CCME WQI has been used to evaluate the quality of treated water [28][29][30][31][32][33][34]. Thus, WQI is also a helpful and useful tool for researchers and decision-makers to monitor and assess the treated wastewater quality for any purpose [33,34].…”

This study aims to evaluate the performance of the sewage treatment plant in Al-Thagher city, in the north of Basrah governorate, the southern part of Iraq. The plant’s performance was estimated based on an analysis of influent and effluent wastewater quality data that represented the monthly averages from Feb. 2017 to Dec. 2018. The results show that the values of temperature (T), pH, ammonia (NH3–N), chemical oxygen demand (COD) and biological oxygen demand (BOD) in all collected samples from the effluent of the plant met the Iraqi water quality standard (IWQS), whereas the values of electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), sulfate (SO4–2), chloride (Cl–1) and phosphate (PO4–P) met the Iraqi water quality standard (IWQS) in some months and did not meet the standard in other months. The average removal efficiencies were in the following order: COD (77.12%) > BOD (77.03%) > TSS (62.26%) > NH3–N (59.99%) > PO4–P (12.42%) > Cl–1 (1.97%). The removal percentages for the remaining parameters had negative values. The Canadian Council of Ministers of the Environment water quality index (CCME WQI) value of the treated water was 51.80 and classified as “marginal.” The coefficients of determination between each parameter in influent or effluent were calculated. Finally, linear regression equations between these parameters were formulated so that the value of one parameter could be used to predict the value of a different parameter.

“…For this reason, methods reducing the number of analyses are being sought, e.g., by establishing the correlation between parameters. Various types of matrix and composite indexes replacing several parameters are created to simplify the procedures of wastewater quality assessment [23][24][25][26][27]. Nowadays, in order to limit measurement campaigns and to facilitate the analysis and evaluation of measurement data, statistical optimization and forecasting methods, also with the use of artificial intelligence, are increasingly used [28][29][30][31][32].…”

Solving urban wastewater management problems requires knowledge of wastewater composition and variability. In the case of combined sewerage, this applies to both dry and wet weather. Wastewater composition is changing as a result of the appearance of new substances on the market, the changes in inhabitant lifestyle and the catchment characteristic; therefore, it must be constantly monitored. At the same time, due to the time-consuming and high costs of measurement campaigns, solutions that could limit their scope and facilitate the interpretation of the results are sought. This paper presents the results of the measurement campaign conducted in 2018–2021. The aim of the monitoring was, inter alia, assessment of wastewater composition in terms of threats to wastewater treatment plant and urban rivers, which are receivers of discharge from combined sewer overflows. The obtained results were analyzed using the multivariate statistical methods: Principal Component Analysis and Cluster Analysis. However, the applied methods did not allow for the full identification of the relationship between the wastewater quality parameters as well as the differences and similarities in the wastewater composition from individual parts of the city, which could simplify and reduce the measurement campaigns in the future. Therefore, in the case of large urban catchments, it is necessary to introduce other solutions to control the wastewater composition.
