الملخص EN

It is necessary to conduct researches and studies on water quality because of the effects on the public health, industrial and agricultural establishments.

A plant of the new Arbil water treats mem was completed since 1.982 where the people in Arbil city were depended completely on groundwater resource*.

This plant uses the oidinarly method for water treatment, where water -passes through preeoesses of.

coagulation, floceuliition, sedimentation, .filtration, and disinfection/ Treatment processes were described, as well as the constituents which are added or subtracted to or from the raw water, and the reactions occuring in each process.

Plan and longitudinal section of Ihe water treatment plant were drawn.

The characteristics of inlet raw water before (he treatment and outlet drinking water after the treatment were tested for five samples in each month of 1986.

The tested characteristics were turbidity.

temperature, pH, total alkalinity, total hardness.

Cl-, Ca++, and Mg++.

The results showed that the tested character!sties of drinking water arc within the allowable.

limits,, only.

the.

total hardness concentration was higher than the allowable limit for industrial purposes, and the turbidity of drinking water was slightly higher than ihe allowable limit.
