Popis: The study aimed to evaluate the quality of entering and leaving water to the textile factory in Diwaniyah and water of AL- Diwaniyah River for the period October 2017 to January 2018, Thirteen sites were selected (three sites) on AL-Diwaniyah River and (ten sites) within Al-Diwaniyah textile factory. The evaluation of water quality includes14 parameters as confirmed on spatial and temporal changes of these parameters in Thirteen sites (S1,S2,S3, S4,S5, S6,S7,S8,S9,S10,S11,S12 and S13). These Thirteen sites are divided into four groups, the first group (water of AL-Diwaniyah river), includes (site 1,site12 and site 13). The second group ((Water prepared for textile industries), includes (site 2 and site 3). The third group (industrial processing water), included (site 4, site 5 and site 6). The fourth group is the treatment unit (Outflow water) that includes (site 7, site 8, site 9, site 10, site 11 and site 12). site 1 (AL-Diwaniyah river water), site 2 (soft water), site 3 (boilers water), site 4 (Water for textile preparations), site 5 (completion water), site 6 (water of printing and dyeing), site 7 (water of primary collection basin), Site 8 (Waters of the sedimentation Basin), site 9 (chemical treatment water), Site 10 (Biological Treatment Ventilated Water), Site 11 (water of Filters), site 12(Final assembly basin (river basin) and site 13 (AL-Diwaniyah river water after distance from the dumping of textile industrial waste). the study includes physical tests, which include Electrical Conductivity (EC), Total Dissolved Solids(TDS), and conducting chemical tests that included pH, Total Hardness (T.H), Calcium (Ca), Magnesium (Mg), Total Alkalinity (T.A), Chlorides(Cl), Sulphates (SO4), Phosphates (PO4) and Nitrates (NO3), as well as heavy metals Chromium (Cr), Nickel (Ni) and Cobalt (Co), For 13 sites inside and outside AL- Diwaniyah textile factory and AL- Diwaniyah River. The results of physical and chemical analysis show the following means of: Electrical Conductivity (2277.75 μs /cm in site 13 to 3991.75 μs /cm in site 11)., Total Dissolved solids TDS (759.75 mg / l in site 2 to 1790.75 mg / l in site 11)., pH (7.94 at site 2 to 9.29 at site 4), Total Hardness (313.25 mg / L at site 1 to 574mg / L at site 9), Calcium (166.25 mg / L at site 1 to 375 mg / L at site 9), Magnesium (21.23 mg / L at site 11 to 70.63 mg / L at site 8), Total Alkalinity (288.75 mg/ l at site 5 to 596.25 mg/ L at site 10), Chlorides (174.75 mg / L at site 2 to 483.5 mg / L at site 4), Sulphate (363 mg / L at site 2 to 521.75 mg / L at site 1). Phosphate (0.29 μg/l at site 3 to 1.315 μg /l at site 6)., Nitrate (21.6 μg /l at site 3 to 37.05 μg /l at site 11) The highest mean of Cr, Ni and Co were (0.145, 0.1745, 0.043 mg / L) at site 9 and the lowest mean of Cr, Ni and Co were (0.00125, 0,061475 mg / L) at site 2 and 13, respectively but CO were (N.D) at site1, 2 and 3. The water quality index values of the water inside and outgoing water from AL- Diwaniyah textile factory generally ranged from (fair to marginal). where the sites located on AL- Diwaniya River (group 1), the site 1 and site 13 got on (fair) were (69.20,67.93), respectively while site 12 got on (marginal) was (51.41)., While sites within the factory (group 2,3 and 4) from (site 2 to site 12) lowest value was (47.82) at site 4 and the highest value was (64.47) at site 2 so the water quality in these sites were (marginal).
