FORERO, J. E; DUQUE, J. J; RIOS, F  and  DIAZ, J. OZONE FOR PHENOL TREATMENT IN INDUSTRIAL WASTEWATER. C.T.F Cienc. Tecnol. Futuro [online]. 2001, vol.2, n.2, pp.17-26. ISSN 0122-5383.

In this study, ozone efficiency on the treatment of wastewater contaminated with high amounts of spent caustic (byproduct from hydrocarbons sweetening processes), is evaluated. The type of feedstock, pH, gas/liquid ratio and influence of catalyst use, are analyzed, in addition to the contact system used for the experiments. As a main conclusion, the feasibility of ozone in the treatment of industrial residues was established, especially in wastewater with high phenol contents.

Keywords : ozone; spent caustic; phenol; chemical oxidation of pollutants.
