| Abstract | ||||
| This study was conducted to evaluate the efficiency of the Excretion Management Station in the Al-Qayyarah refinery in Nineveh Governorate, as well as addressing the impact resulting from the industrial discards on the characteristics of the water of Tigris River and its validity for domestic, industrial, and agricultural uses. Numerous environmental factors were evaluated, viz. pH, total hardness, calcium hardness, magnesium hardness, sulfate, phosphate, chloride, total solid, total dissolved solid and suspended solid. A remarkable variation in concentrations was recorded during the study period. The highest value of pH was 7.7, while the lowest was 6.6. The electrical conductivity (EC) ranged between 902 [1] & 674µmhos/ cm before treatment, while after treatment, chloride ion recorded values between 16 & 44mg/ L; before treatment, the highest value of sulphate (SO4)[2] was 218mg/ L and the lowest was 40mg/L. In addition, orthophosphate (PO4-3) recorded a high value of [3] 6.1mg/ L & a low value of 0.1mg/ L. 902 اينما تذكر كلمة sulfur تحول الى Sulphate SO4 اينما تذكر كلمة phosphor تحول الى Orthophosphate PO4 | ||||
