English Abstract

The study was accomplished for the evaluation of the efficiency of the processing station of excretion in Al – Qayyarah refinery, which is located in the area of Al – Qayyarah town toward the south east direction of Mosul city / Iraq.

For this purpose, monthly samples were collected for five months from November 2013 to February 2014.

Physical, chemical and biological tests were carried out on the samples including Electrical Conductivity, Total Dissolved Solid, Turbidity, Hardness, pH, Sulphate, Sodium and Potassium ions, Heavy metals, Oil,Chemical Oxygen Demandand the Total number of bacteria.

The results of this study showed that there was clear variations in the values of those variables before and after treatment,such that values of the acidic function before treatment ranged between (7-8.1) compared with the value after treatment which ranged between (6.9-8.2).the values of Electrical Conductivity was (460-720)μmhos/cm before treatment while the values after treatment was(350-630)μmhos/cm the rate of total hardness before treatment was (233.8) mg/L compared with it’s rate after treatment (238.6) mg/L the nitrates ranged between(0.403-1.341)mg/L before treatment and (0.470-1.423) mg/L after treatment and for sulphate the values ranged between (56.16-67.416) mg/L before treatment compared with values after treatment which was (55.33-69.83) mg/L, the values of concentration for the heavy metals(Pb, Co, Cd, Cu) before treatment was (1.536-1.627), (0.05793-0.06644), (0.04794-0.04821), (0.5378-0.5733) mg/L and thevalues after treatment was (1.324-1.410), (0.06899-0.07814), (0.04845-0.06227), (0.5623-0.5825) mg/L and the total number of bacteria was between (100-1100) cell/ ml before treatment comparedwithresults after treatment (300-3000) cell/ml.

The results show that the station’s pollutants removal was not efficient.
