Emerging micropollutants in water/wastewater: growing demand on removal technologies.
Developing advanced treatment technologies for improving the removal of micropollutants in water/wastewater is important. A suitable treatment is more likely to be used as the polishing step in the treatment scheme. Advanced oxidation technologies (AOTs) are relevant for removing micropollutants. The ability of direct UV photolysis and selected AOTs to degrade pharmaceuticals, endocrine-disrupting compound and herbicide has been studied and compared. The tested methods resulted in the degradation of the studied micropollutants; however, none of the methods was preferred for the removal of all tested compounds. The UV-active processes have strong potential for removal of the studied micropollutants. The utilisation of a moderate hydrogen peroxide admixture resulted in a more reliable treatment.
