Performance de la station d’épuration Ain el kihel : Analyse et Simulation

Abstract

Wastewater is one of the main sources of pollution resulting from domestic, industrial, and commercial activities. With increasing urbanization and population density, the volume of wastewater continues to grow, leading to serious environmental and health challenges. Therefore, the implementation of effective treatment systems has become an urgent necessity to protect public health and preserve ecosystem balance. This study focuses on evaluating the performance of the Aïn El Kihal wastewater treatment plant, which uses the activated sludge process for treating domestic wastewater. Two main approaches were adopted in this work :  A physico-chemical analysis of the influent and effluent, aimed at assessing the plant’s effectiveness in pollutant removal.  A numerical simulation using the GPS-X software, an advanced tool used to model treatment processes and identify performance improvement strategies. As part of the plant’s performance monitoring, a comparison was carried out between the experimental results obtained from laboratory analyses and those generated by the simulation software. This comparison revealed a good correlation between the data, demonstrating both the reliability of the plant's performance and the accuracy of the digital modeling. High removal efficiencies were recorded for key biological and physical parameters such as BOD5,COD, NH4+, and TSS.
