Abstract
The process of recovery and reuse of water treatment sludge as a coagulant perform a sustainable solution that benefices economically and environmentally. High safety concerns are to be take in consideration during reuse of water sludge in water purification. Most of the previous researchers have applied several full-scale separation methods for an effective purification of coagulant, without pointing to the performance of the coagulant treatment. In this research we studies the characteristics of sludge resulted from the treatment process of raw water from the river Nile, then the produced sludge is chemically treated with an acid in order to reuse it again in coagulation. Acidified water treatment sludge performance in removing turbidity and dissolved organic carbon DOC have been evaluated. The optimum coagulant dose determined for coagulation process of raw Nile water was 36 ml/l, while the optimal pH range concluded for higher turbidity removal was from 6 to 8. The resulted water treatment sludge found to be reliable to use in conventional water treatment process. The study recommended for better performance of coagulation, to add a partial amount (at least 20 % of coagulant dose) of the proper coagulant to the recovered water sludge
