Abstract: ABSTRACT The hospital sector discharges a large quantity of polluted wastewater. Proper management of these discharges requires prior precise characterization of their complex composition in order to adapt the mode of their treatment. The present study was interested in the physico-chemical and microbiological characterization of the effluents generated by three large hospitals of CasablancaSettat region of Morocco. This characterization was made on representative samples taken at the level of the main collectors of the hospitals concerned by the study before they cross other discharges. The results showed that the degree of pollution of the effluents studied is relatively high. Electrocoagulation treatment using aluminum electrodes has been shown to be effective and is improved with the optimum current density (J) applied, the best results are associated with densities between 142.85 and 285.71 A/m 2 . Electrocoagulation treatment is therefore a very promising effective and economical solution adapted to hospitals in Casablanca-Settat region, known as the most polluted area of the country.
