Abstract
The production of solid waste, which is increasing on a global scale, presents considerable impacts linked to the environment. The storage of this waste in anaerobic conditions makes it possible to produce a large volume of leachate, which is harmful to the environment. This study concerns the sizing and design of a system for treating leachate (young and stabilized) by nitrification–denitrification, coagulation-flocculation followed by filtration on materials. The results showed that the optimal concentrations of FeCl3 used as a coagulant vary between 6–8 and 4–6 for young and stabilized leachates for a pH of around 8.5. This work constitutes an interesting case study, making it possible to reduce leachate pollution produced by a public landfill using a simple technology. This work includes an interesting case study, making it possible to minimize leachate pollution produced by a public landfill using a simple technology. The results obtained in the laboratory on a pilot scale showed that the proposed steps are complementary and make it possible to reduce pollution effectively. However, using the treatment plan to discharge leachate stored in Basin 3 is more enjoyable, which presents a reduced pollutant load compared to the quality of raw leachate received by Basin 1. The sector's design based on the determined optimal conditions makes it possible to minimize pollution considerably. Furthermore, calculating the sector's costs remains moderate, which could encourage establishing the industry in development.
