التقييم الفيزيائي للمياه الخام لنهر دجلة في مدينة بغداد

الملخص EN

Potable water is one of causing sources of different diseases, therefore it is preferred to do continuous researches for the quality of water fitted to the role of citizens through large projects and compact units and other compounds that processed millions of liters per day.

Within this trend, the current research applied to show the effect of physical properties on the water quality of the Tigris river passing through city of Baghdad by physical testing of raw water supplied to compact units.

The physical tests data of the Tigris River collected during a full year from January until Dec.

2010 had analyzed by drawing the results of maximum monthly values of the physical tests and compared with the specification limits.

The statistical analysis had done for the results of these tests in two ways, computation of the correlation coefficient(R) and the one-way variance testing (ANOVA).

Most of the parameters were outside of the specification.

The results of statistical analysis were logical, also it is shown that the proximity between months of September and October and away the months of July and December was because of the seasons different, as well as the proximity of (EC and TDS) is happened in order to the positive relationship between them.

The most important conclusions of the study was that the supplied water (Raw water) to the projects is acceptable for supply especially TDS, as well as the specifications of the raw water are generally degraded (especially salinity) at the progress towards the south through the center of the capital.
