The comparison of the efficiency of three ozonation systems (ozonation alone and ozonation in the presence of alumina or PFOA) in attempting the removal of aromatic hydrocarbons from water was made. The results obtained indicate that PFOA shows a great catalytic activity, as opposed to alumina. Moreover, ozonation in the presence of PFOA results in a much higher level of ozonation efficiency in comparison to ozonation alone. The effect of ozone dosage, catalyst dosage and pH value was investigated and was found to have a great influence on hydrocarbons removal efficiency. The degradation rate was shown to decrease with increasing ozone and catalyst dosage. The efficiency of the PFOA/O-3 system was observed to be at its greatest at the lowest pH examined.
