| Abstract | ||
| The turbidity of Al-Eiz river water has been removed in a pilot plant designed and constructed locally. The local lime, ferrous sulfate and polymer have been used as coagulants and the last as a coagulant aid with ferrous sulfate for different levels of turbidity. Chemical pretreatment of the river water was first investigated on a laboratory scale to optimize the coagulation and flocculation conditions with respect to the turbidity, and zeta charge indexes after sedimentation and filtration processes. Experimental investigations have been carried out in a pilot plant to determine the optimum dosages of coagulation and coagulation aid required to reach the permissible limits of turbidity. The results were discussed and compared with the worldwide standards where a good agreement has been observed. | ||
