| Popis: | One of the main obstacles to the management of public landfills is leachate from urban garbage. They do pose a harm to the environment and to human health given the amount of pollutants they contain. Depending on the type and age of the waste, the climate, and the terrain of the location, each landfill's composition is different. One of the locations with a leachate management issue is the controlled landfill in Greater Agadir. Leachates have been reduced using a recirculation and sprinkler system, although efficiency is still very poor. The leachate water was diagnosed as having significant organic contamination. This study aims to describe the leachates from several Greater Agadir areas and assess the efficacy of the coagulation-flocculation method of treatment. FeCl3 considerably changed the hue of the leachate, which had a neutral pH, 90% turbidity, and 78.2% COD elimination. This leachate appears to be best suited for modest doses of 3g/L. The research conducted here has also demonstrated that the polyacrylamide flocculant, with a mass of 3 g in the presence of a mass of 3 g ferric chloride, has a turbidity level of 92% and 97% for COD. For 3 g/L of ferric chloride, however, the bioflocculant from "Opuntia cactus" juice also provides good flocculation, with a turbidity removal rate of 98.14% and a COD removal rate of 87%.
