Evaluation of some chemical and physical properties of the liquefaction plant in al-dibs district - kirkuk governorate

This research to evaluate some chemical and physical characteristics of water in Al-Dibs district located in Kirkuk governorate, Iraq, from October 2023 to March 2024. Samples were collected from different water sources including the Zab River, Dibs Liquefaction Plant and public supply networks during different seasons to ensure accurate representation of seasonal conditions. Total Suspended Substances (TSS) values in drinking water were recorded within a range of 0.22-1.42ppm. Total alkalinity (TA) - ranged from 100 to 140 ppm. The results for total hardness (TH) showed variation between 120 and 230 ppm. The calcium (CaH) and magnesium (MgH) hardnesses were recorded in the range of 85-165 and 25-65 ppm, respectively. Chloride ion (Cl) concentrations ranged between 5.68 and 31.24 ppm. As for nutrients, the total nitrogen (TN) concentration was between 0.1% and 0.2%, while the available phosphorus (TP) concentrations were very low and ranged from insignificant values to 0.11 ppm. The results of analysing the drinking water in Dibs district showed that the water is generally fit for use, but contains some high values in hardness and nutrients, indicating the need for continuous monitoring and simple improvement in treatment to ensure its quality and safety.
