Abstract

This study aimed to study the physical and chemical qualities of Al-Hilla water net by choosing eleven stations, three inside the water station in the successive precipitation, filtration and chlorination processes and eight are chosen according to its distance to Al-Hilla water station during December 2017. The parameters measured were temperature pH, total solids, dissolve solids, electrical conductivity, turbidity, total hardness, calcium, magnesium, residual chlorine, chloride, sulfates, total phosphates and biochemical oxygen demand (BOD5). The study presents pH tends to balance in the river and the water station and network. The total solids, dissolve solids, turbidity and electrical conductivity decrease clearly in the water station and network in comparison with the river. The magnesium, residual chlorines, chloride, calcium and sulfates do not change clearly in the water station and network. The pH, total solids, turbidity, total hardness, calcium, magnesium chloride and sulfates were within the standard measures of WHO. The values of residual chlorines and BOD5 are a little more than that and in spite of this it is regarded as drinking water. The BOD5 falls within the well classification of drinking water and domestic usage based on Iraqi qualities. Finally, no total coliform or fecal coliform found in Al-Hilla water station after its treatment with chloride.
