Like any other industrial segment, drinking water treatment plants produce residues from the processes of decantation and filter washing. A large quantity of water treatment residues is generated each year from fresh water treatment plants (Huang et al., 2005). The usual practice is to discharge these residues into rivers without any treatment. This procedure is not in accordance with cleaner production practices since its degrades not only the quality of the rivers increasing the concentration of solids, silting,causing color changes and turbidity, inhibiting biological activity,and increasing the concentrations of aluminum, iron, and some other elements; but it also poses a danger to the lives of current and
future human generations.
