ALMEIDA, Edna; ASSALIN, Márcia Regina; ROSA, Maria Aparecida  and  DURAN, Nelson. Wastewater treatment by oxidation with ozone. Quím. Nova [online]. 2004, vol.27, n.5, pp.818-824. ISSN 0100-4042.

A large variety of organic and inorganic compounds may be found in wastewater which can contribute to environmental contamination. Oxidation processes with ozone (O3; O3/UV; O3/H2O2; O3/TiO2; O3/Mn+2) and the use of ozone in the pre- or post-treatment of wastewater combined with biological processes has been extensively studied for the treatment of effluents. The aim of this work was to evaluate the potential of the ozonation process in the treatment of several industrial wastewaters, namely effluents from paper mills, and textile, whey (dairy industry), pharmaceutic sand pesticides plants.

Keywords : ozonation process; treatment; industrial effluents.
