ABSTRACT: The total petroleum hydrocarbon (TPH), polycyclic aromatics (PCA), nonvolatile suspended solids and volatile suspended solids besides other important parameters, total hardness, calcium hardness, CO2 content, total dissolved solids, electrical conductivity, sedimentation time, chemical oxygen demands, biochemical oxygen demands, pH value after sedimentation and pH after coagulation in aerobic treatment are surveyed due to the changes in fast mixing rate. The experimental results show the TPH removal percentage and PCA removal percentage increases from 53.5% to 62.8% and 43.8% to 46.3% with increasing of nano dosage from 1 gr to 2.5 gr, respectively.
