Traitement des eaux

Objectives

Through a process engineering approach, to introduce conventional treatment techniques in the production of drinking water, treatment of wastewater and sludge, then study of unit operations liquid/solid treatment.

Description

Drinking water treatment :

• Conventional treatments: coagulation-flocculation, decantation, filtration, disinfection ;
• Desalination of brackish water and sea water ;
• New treatments: membrane processes, nitrification, denitrification.
• Sizing of unit operations: filtration, membrane filtration, chromatography and decantation/centrifugation

Sanitation :

• Implementation of stations, characterization of urban effluents;
• Pretreatments: storage, screening, sieving ;
• Primary treatments;
• Secondary treatment.

Sludge treatment and valorization :

• Thickening ;
• Aerobic and anaerobic sludge digestion; dewatering
