Ozonation of Phenol Occurring in Waste Water Polluted by BHT Oils in Presence and Absence of TiO2 Catalyst

In this work advanced oxidation process was investigated for removal of phenol from water polluted by BHT oils using 3 O alone and ozonation catalyzed with Titanium oxide (2 TiO). Effect of catalyst and dose of it on degradation of phenol have been studied at pH 7. Some studied parameters like catalyst, ozonation time and ozone flow rate had positive effect on increasing the rate of ozonation. The results of HPLC and UV analyses were used for detecting of phenol during ozonation reaction and study the effect of TiO2 catalyst on the degradation rate of phenol. TOC and COD removal percentage have been detected in different ozonation times in presence and absence of catalyst. The effect of ozone flow rate on degradation of phenol and also, removal of COD and TOC has been studied. The present study validate that ozonation is a safe, economic and promising process for the removal of phenol from different industries waste water.
