Le projet consiste à faire un recalibrage, une réhabilitation et une extension en mode « conception & réalisation » des STATIONS D’’EPURATION Sud Méliane II comme suit :
• Abandon des STATIONS D’’EPURATION I (tous les ouvrages de la SMT)
• Maintenance of SM II works
Transform the existing SM II WWTP into two separate quasi autonomous plants: a plant for urban water called the Urban sector and a sector intended for urban water including industrial water called the industrial sector.
Increase its hydraulic capacity from 40,000 m3/d to 90,000 m3/d and its biological capacity from 20,000 kg DBOS/d to 36,000 kg DBOS/].
- Independent treatment of effluents and sludge from the "urban" and "industrial" processes to reuse treated water from the "urban" process for irrigation and to use the sludge in agriculture.
Add a new pretreatment unit next to the SM II pretreatment
Add a primary settling structure
- Add a secondary settling structure
- Add a thickener
- Add sludge digestion facilities, digested sludge storage tanks, cogeneration
- Add a new sludge dewatering room
