Abstract

Aim of this study is to elaborate low-cost solutions for the pre-treatment of textile effluents in Morocco. A wastewater from a dyeing mill in the city of Mohammadia with high organic load served as an example. Coagulation-flocculation with Al₂(SO₄)₃ removed 99.4% of turbidity and led to a Chemical Oxygen Demand COD decrease of 92.9%, other coagulants were also effective (Fe₂(SO₄)₃, FeCl₃ and CaO). The application of a coal fly ash shows that the adsorption process leads to a COD decrease of 36.8%. The suspended matter can be totally eliminated by a simple sedimentation procedure.
