Drinking water in Egypt is provided by the Nile river. Aluminum sulfate are widely used as coagulants in the drinking water treatment processes in Egypt. Residual aluminum may cause several environmental consequences. Hematite nanoparticles have been used as coagulant in water treatment to avoid residual aluminum problems. There is a comparison between hematite nanoparticles and alum in coagulation process for drinking water treatment. Raw water samples were collected from Nile river Rosetta branch at Basyoun city at the uptake site of Basyoun's drinking water company. Hematite nanoparticles satisfy many crucial requirements including non-toxicity, indefinite stability, low cost and ease of production. In this study, experiments were conducted on nanoparticle of hematite ability as coagulant for drinking water treatment. The results show that the highest turbidity removal by hematite nanoparticles of values up to (93.8)%.
