EXPLOITATION OF THE DOMESTIC WASTEWATER TREATMENT PLANT BY ACTIVATED SLUDGE IN THE AIRPORT AREA OF THE CITY BEN SLIMANE (MOROCCO)

Abstract

Abstract. Domestic wastewater (toilet water and household water from kitchens) is evacuated in unit or separate networks to the purification station (STEP) in order to eliminate their waste; organic and mineral matter, dissolved and suspended before discharging them into the natural environment or reusing them in irrigation. The main purpose of this work is to operate the wastewater treatment plant in the Ben Slimane Airport area by using activated sludge, this process consists of destroying pollutants and microorganisms by bacteria formed in the clarifier. Moreover, the operation of the station was considered by controlling the sensors installed in each basin to promote their optimization, in addition, the physicochemical analysis was carried out in the STEP laboratory. The results found for the parameters studied showed the very effective reduction of the organic load of the wastewater treatment plant, so these values meet the discharge standards defined by Moroccan legislation.
