RODRIGUEZ, Tatiana; BOTELHO, Diego  and  CLETO, Eduardo. Treatment of industrial effluents of recalcitrant nature using ozone, hydrogen peroxide and ultraviolet radiation. Rev.fac.ing.univ. Antioquia [online]. 2008, n.46, pp.24-38. ISSN 0120-6230.

Currently diverse industries have high pollution potential because their productive processes generate great volumes of refractory effluents. These effluents are problematic, mainly due to the presence of recalcitrant compounds that are detrimental in wastewater treatment plants using biological systems in their processes. In general, biological treatments do not remove refractory elements. Also, in most cases these compounds can inhibit the yield or are toxic for biota responsible to remove the polluting agents. The Advanced Oxidative Processes (AOPs) represent a technological alternative with a great potential for treatment of no biodegradable effluents. In this paper a review of the use of advanced oxidatives processes: Ozone (O₃), peroxide of hydrogen (H₂O₂) and ultraviolet radiation (UV) is presented applied to the treatment of recalcitrant effluents.

Keywords : AOP; ozone; hydrogen peroxide; ultraviolet radiation; recalcitrant effluent.
