Sludge produced in drinking water treatment plants (DWTP) is discharged into environment every day, even they are rich in phosphorus-reactive elements. The objective of this study was to evaluate the removal of phosphorus using sludge from DWTP of the city of Sinematiali (Côte d’Ivoire). The sludge was packaged in granules and put in contact in beaker with synthetic water et effluent from domestic wastewater treatment plant. The results demonstrated that the sludge was rich in aluminum (307.6 ± 0.6 g/kg) and iron (208.7 ± 1.2 g/kg), two phosphorus removal agents. Phosphorus removal was described mainly by adsorption process, which equilibrium was reached after 4 h of contact time at pH 5. Removal of phosphorus from wastewater was around 70% in synthetic wastewater and 42.5% in real wastewater. Removal rate was enhanced when the sludge dosing increased from 10 to 40 g/l, from 42.5 to 87.5%. The adsorption of phosphorus is described by the Langmuir isotherm with qm = 1.72 mg/g and kinetic removal followed pseudo-order 2 model (k2 = 0.023 g/mg.min). Sludge from DWTP of Sinematiali demonstrated good phosphorus removal potential.
