    Etude des paramètres physicochimiques et biologiques des eaux usées avant et après traitement de la station d’épuration de Ain El Beida (W. Oum El Bouaghi)

    Today, climate change is considered a serious threat to the availability, quantity, and quality of surface water and groundwater. Countries in arid and semi-arid regions must plan to address water shortages by sustainably and efficiently exploiting water resources. The reuse of properly treated wastewater for irrigation is a promising strategy. During their treatment, wastewater is exposed to various weather events that can alter its characteristics. This study evaluated the treatment efficiency of municipal wastewater by the wastewater treatment plant of the city of Aïn Beida (W. Oum el bouaghi) based on Physicochemical and biological data from the period 2023-2024. By utilizing the measured Physicochemical parameters, the treated water was classified according to its quality and compared with national and international standards. The effects of extreme weather events, precipitation, and rain indicators on the water quality index of treated water were tested, and comparisons were made between raw wastewater and treated water. The majority of the studied parameters were compatible with national and international standards. With high purification efficiencies, up to 100% for TSS, COD, and BOD5, the performance of the wastewater treatment plant is among the best at the national level compared to other stations. The WQI values reveal that 96% are of excellent quality. Extreme weather parameters do not have significant effects on quality variation, except for precipitation, which improves the incoming water by diluting pollutants.
