The effect of different treatments on the degradation of chlorinated organic pollutants in wastewater has been studied. The model compound investigated was para-chlorophenol. The different treatments used were ozone, UV irradiation, ultrasound, air flow and pure oxygen.

It is concluded that ozone has the greatest effect, ozone-UV irradiation follows closely behind, and UV irradiation has much less of an effect in degrading the p-chlorophenol.

P-chlorophenol was found to have an immeasureably slow degradation rate when treated with air even at an elevated temperature of 55°C.

The oxygen, at room temperature, showed a degradation of p-chlorophenol which, although small, was much greater than that of air at the higher temperature.
