PHYSICOCHEMICAL, ELEMENTAL AND SPECTROSCOPIC CHARACTERIZATION OF SEWAGE SLUDGE FROM THE JIJEL WASTEWATER TREATMENT PLANT (ALGERIA) FOR AGRICULTURAL VALORIZATION
Agricultural valorization of sewage sludge represents a sustainable management strategy that contributes to nutrient recycling and soil improvement. However, its safe use requires comprehensive physicochemical and mineralogical characterization. This study aimed to characterize sewage sludge collected from the Jijel...
