Treatment of Emerging Contaminants in Wastewater by Advanced Oxidation Processes / ANNA CATTON

Swansea University Author: ANNA CATTON

Abstract

This study evaluated the effectiveness of ozonation and activated carbon for the degradation and removal of three main emerging contaminants (ECs) in wastewater; fluoranthene (FLT), di (2- ethyl hexyl) phthalate (DEHP) and cypermethrin (CYM). The effects of key semi-batch ozonation parameters relate...
