| Abstract | ||
| Drinking water treatment plants (DWTPs) are supposed to be one of the most important operation challenges. For that, raw water resources must be selected and controlled. DWTPs facilities must be qualified and be efficient to give good and healthy quality. In this view, assessments were focused on nitrogenous compounds and microbial load of raw water of the downstream canal and its relationship. The comprehensive removal efficiency of physicochemical and biological contaminants during the treatment process was followed up. Raw water during the period of study which extended for a full annual cycle had levels of contaminants that were not suitable for proceeding through different stages of treatment (physically, chemically, and biologically). Raw water ammonia-N ranged between 0.23 ppm and 11.06 ppm and the mean value was 0.53 ppm. On the other side, biological parameters had more interest in which tests were applied on raw, clarified, filtered, and treated. The result of treated water was accepted and good where there is the removal of contaminants step by step during the treatment process. At high ammonia concentration, the turbidity has a negative correlation with the removal of microorganisms after injection of initial chlorine. | ||
