Study of the water and suspended material quality in Tikrit university potable water plant / Iraq

Abstract

Three stations were selected and collected (3) four water samples (Sedimentation basin, chemical treatment basin, filtration basin), including measurements of the physical and chemical characteristics of the water: pH, Electrical Connectivity (EC), Total Dissolved Solids (TDS), and Total Hardness (TH).It included chemical analyses for the main components of water samples for cations such as: Sodium Na+, Potassium K+, Calcium Ca++, and Magnesium Mg++, and anions such as Chloride (Cl-), Sulfate (SO4=), and Bicarbonates (HCO3-), and nitrate (NO3-) as minor component, and some trace elements such as Iron (Fe), Copper (Cu), Zinc (Zn), lead (Pb), Nickel (Ni), and Cadmium (Cd). The chemical tests of sediment include measure the trace elements such as Cobalt (Co) Iron (Fe), Copper (Cu), Zinc (Zn), lead (Pb), Nickel (Ni), and Cadmium (Cd) and Chrome (Cr), also created the three sample for mineral test using X-ray diffraction in general company for geological survey and mining, where a representative sample of the main sample was taken (Normal) to determine the clay mineral, and then add ethylene glycol, heating 350 and heating 550, and calculate ratio of clay mineral in sediment sample by measure area under curve. The results of physical and chemical analyses for the water samples after comparing them with standard specifications showed their validity there is an increase in concentration of some major Ions such as potassium and sulfates.And the result of sediment test show increase in concentration of trace element(Co, Cu, Zn, Ni, Fe), that lead to increase in pollution of drink water, and the result of mineralogical study observed a metal clay (Chlorite, Montimorillonite, Illite, palygoriskite and kaolinite), the presence of clay mineral in the clay of filteration and sediment basins have negative side represented in difficult to remove these mineral from the basins and thus causing block the nomination of water
