Ozone for phenol treatment in industrial wastewater
Abstract
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.
