Evaluating the Water Treatment Efficiency of the Plant Sewage in the Tuz Khurmatu District

Abstract

The research includes a study of evaluating the treatment efficiency of the sewage plant in the Tuz Khurmatu district during the period from September 2020 to July 2021. Three study sites have been selected. The study includes measuring certain physicochemical and biological properties of water (the biological properties include studying the quality of algae). As for the physicochemical properties, they include measuring (air and water temperature, pH, dissolved oxygen, biological oxygen requirement (BOD5), active phosphate and active silicates).The results found that air temperature ranges between 12-49°C, while the water temperature ranges between 9-40°C. The pH values have a wide range during the months of the study ranging between 6.20 -8.45. The values of the dissolved oxygen range between 1.25-3.10 mg/L, and the values of the biological requirement for oxygen range between 19.2-47.2mg/L. The study also shows that the wastewater during the study period is of a light basicity in which bicarbonate ions prevail. Nutrient concentrations fluctuate depending on the nature of the site and the date of sample collection, as the effective phosphate ranges between 2.32-7.76 mg phosphorous-phosphate/liter. As for the silicate values, they range between 0.38-6.61 mg atom of silicon -silica / liter.
