Abstract

Chlorine  is one of the basic
sterilizers in the process of sterilizing drinking water in most countries of
the world for its wide availability and low cost where it works to eliminate the causes of diseases in drinking water effectively
through the destruction of membranes and attack the basic enzymes of those
organisms. The process of sterilization of chlorinated
drinking water depends on the added chlorine dose and the contact time the residual chlorine is of great importance in maintaining the quality
of drinking water. Therefore, the residual chlorine concentration in the
drinking water of the city of Kirkuk was studied and some factors affecting
them such as water temperature turbidity electrical conductivity total soluble
salts and pH of five stations by five samples per station during the study
period, which lasted between January and July 2017.

The results of the study showed that the concentration of residual
chlorine ranged from 0.8 - 3 mg / L where it was higher than the limit allowed
within the standards also the results showed an inverse relationship between
residual chlorine concentration and water temperature While the turbidity and concentrations of total dissolved solids,
electrical conductivity, and pH were within Iraqi standards.

Concentration of Residual Chlorine and Its Health Effects on The Drinking Water of The Kirkuk City

Abstract

Chlorine
is one of the basic sterilizers for
the drinking water in most countries due to its wide availability and
low cost, which it works to eliminate the causes of diseases in drinking water
effectively through the destruction of membranes and attack the basic enzymes
of those organisms. The sterilization process of chlorinated drinking water
depends on the added chlorine dose and the contact timethe residual chlorine is
of great importance in maintaining the quality of drinking water. Therefore,
the residual chlorine concentration in the drinking water of the city of Kirkuk
was studied by some factors such as water temperature turbidity electrical
conductivity total soluble salts and pH of five stations by five samples per
station during the study period, which lasted between January and July 2017.
The results of the study showed that the concentration of residual chlorine
ranged from 0.8 - 3 mg / L where it was higher than the limit allowed within
the standards. The results also showed an inverse relationship between residual
chlorine concentration and water temperature while the turbidity and
concentrations of total dissolved solids, electrical conductivity, and pH were
within Iraqi standards.
