As revealed by many studies conducted in both pilot and full-scale it is clear that ozone, being a powerful oxidant, not only removes organics and micropollutants in the wastewater but also reduces the toxicity significantly. Ozone has proved its capacity to reduce wastewater ecotoxicity to both aquatic plants and animals and invertebrate species. Another important contribution of ozone with environmental significance is the removal of estrogenicity knowing that endocrine disrupting chemicals is becoming more abundant and widespread in our environment. These, in addition to its excellent disinfection efficiency against bacteria and viruses, demonstrates that ozonation is a valuable option for wastewater treatment plants and water industry. In some cases, ozone can be combined with other treatment technique where certain effluent quality standard have to be met, as an example for water reclamation purposes.
