Hospital wastewaters are considered to be one of the major sources of emergent contaminants as result of the dairy activities and excretion of the patients. Several studies have demonstrated that these compounds are not easily removed in conventional wastewater treatments that use biological process. This study evaluated the removal of the organic matter present in real hospital effluent applying ozone
The ozone application seems to be a viable alternative to treat hospital effluents as a pretreatment of a biological process.
