Abstract :
We considered the treatment of domestic wastewater by coagulation¯¯adsorption coupling with ultrafiltration as an alternative for wastewater reclamation and reuse. The flocculation¯¯adsorption process showed good performance in removing the chemical oxygen demand 86% at a FeCl3 concentration of 40 mg/l, and powdered activated carbon concentration of 20 mg/l. In the same way the turbidity passed from 18 NTU to 3.5 NTU at pH = 5.5. Laboratory tests showed that the turbidity is passed from 18 NTU to 0.5 NTU by the process flocculation¯¯adsorption¯¯ultrafiltration and removal efficiency of chemical oxygen demand 82.7% (where the value passed from 77 to 13mg/l).
