PHYSICAL AND CHEMICAL STUDY OF OUTLET WATER FROM WASTEWATER TREATMENT OF ALKASSIK REFINERY
Main Article Content
Abstract
This study was conducted on the water outlet of treatment station of AL-Kassik refinery, samples collected in the rate of on sample per month and covered the period from October 2013 to May 2014. Physical and chemical parameters were measured for each sample the analysis involved (Water Temperature, Turbidity, Electrical conductivity, Total dissolved solid, pH, Total hardness, Dissolved Oxygen, biological oxygen demand, Chemical oxygen demand, Sodium, Potassium, Chloride, Sulfate, Nitrate, Phosphate).the study results shown that the Oxygen demand values ranged between (2.95-6.0) mg/l with average concentration (5.15) mg/l, The Biological oxygen demand values ranged between (1-1.2) mg/l with average value of (1.5) mg/l. whereas Chemical oxygen demand results shows the concentration average of COD (132.2)mg/l these results indicates that the water was in polluted and organic cleaned. The total hardness range between (180.1-230.2) mg/l these indicators that water flow for treatment station was very hard, finally, the obtained results indicates that the treatment station of AL-Kassik refinery has a good efficiency to the standard values of water quality to (EPA).
