DOI: 10.22161/ijeab/2.1.20

Abstract:
Two studied stations were involved in this study included Sharq–Dijla and Al-Karamah water purification stations. Water samples collected from four sites with three replicates for each sample of each site of the river and the station: before, after, inside the stations and at the pipe. The study started in October 2012 to September 2013. Results showed that the minimum level of water temperature was 11oC during (December-January) at Sharq –Dijla.While the maximum level was 30oC during (August-September) at both AL-Karamah and Sharq –Dijla stations. pH results revealed that the highest level of pH was 8.63 during (October-November) at AL-Karamah station followed by the lowest level was 6.73 in(February- March) at Sharq –Dijla station. The highest level of EC was 1068 µS/cm during (April-May) at Sharq-Dijla station, while the lowest level was 693 µS/cm during (August- September) at the same station. The results of DO showed that the highest level was 11.51 ppm during (December-January) at Sharq- Dijla station, while the lowest level was 4.25 ppm during (August- September) at AL- Karamah station.The BOD results recorded the highest level of BOD5 was 4.49 ppm during (August- September), and the lowest level was 0.67 ppm during (December-January) both results at Sharq-Dijla station. Total hardness showed that the highest level was about 404 ppm during (December-January) at AL-Karamah station, and the lowest level 162 ppm during (August- September) at the same station. Free chlorine measurements found with Iraqi limits and WHO for these two stations. The highest value of Iron concentration was 3.30ppm in (December-January) at Al-Karamah station, while the lowest value was1.63ppm in (August- September) at Sharq–Dijla station.
