Correlations between some operation parameters and efficiency evaluation of domestic wastewater treatment plant in Tunceli (Turkey)

The purposes of this work are to monitor certain operating parameters in influent and effluent of domestic wastewater treatment plant in Tunceli, Turkey, to determine the relationships among these parameters, and also to evaluate the effectiveness of the treatment plant. The mean values of the parameters measured in the samples taken from the plant influent like pH, temperature, electrical conductivity, dissolved oxygen, total dissolved solids, suspended solids, the total solids, volatile suspended solid, biological oxygen demand, and chemical oxygen demand, are 7.60 +/- 0.07, 11.66 +/- 0.74 degrees C, 1,070.75 +/- 10.67 mu s/cm, 3.78 +/- 0.32 mg/L, 524.42 +/- 5.28 mg/L, 390.58 +/- 40.22 mg/L, 857.50 +/- 61.30 mg/L, 496.17 +/- 82.30 mg/L, 195.33 +/- 8.11 mg/L, and 653.67 +/- 42.12 mg/L, respectively. The values of these parameters after the treatment are 7.68 +/- 0.08, 10.61 +/- 0.70 degrees C, 1,041.25 +/- 15.31 mu s/cm, 8.38 +/- 0.10 mg/L, 510.17 +/- 7.49 mg/L, 49.17 +/- 8.88 mg/L, 443.08 +/- 38.95 mg/L, 152.33 +/- 27.95 mg/L, 13.67 +/- 2.33 mg/L, and 44.66 +/- 12.72 mg/L, respectively. Correlation analyses conducted to explain the potential relationship between the analyzed parameters demonstrated that there were both negative and positive correlations between the influent and effluent operational parameters. Results supported the fact that there were significant improvements in wastewater quality after treatment.
