Description
This study assesses the performance of a prototype activated sludge pilot system developed for the treatment of secondary-treated urban wastewater (SWW). The system was designed to emulate the fundamental processes of biological wastewater treatment through the activated sludge method. Daily sampling was conducted at both the influent and effluent points of the reactor, with key physicochemical parameters monitored using standardized analytical protocols. The findings revealed effective biomass development, with total suspended solids (TSS) reaching 2 g/L and volatile suspended solids (VSS) at 1.4 g/L. The system achieved pollutant removal efficiencies of 92.11% for nitrites, 75.82% for nitrates, 80.10% for Ammonium, 81.66% for Total Nitrogen, 79.6% for total phosphorus, and 57.3% for chemical oxygen demand (COD). These results highlight the efficiency of the pilot-scale activated sludge system in treating wastewater and confirm its compliance with Moroccan discharge standards.
