[EN] Endocrine disrupting compounds (EDCs) that originate from household pharmaceuticals and personal care products are growing concerns due to their increasing occurrence in surface and ground water around the world. Conventional water treatment technologies have been proven ineffective against these micro-pollutants. Laboratory and pilot-scale studies have shown that ozone degradation and membrane filtration are two promising technologies for treating EDCs. However, membrane fouling by organic matters and low minerization rate of ozone degradation limit their development in water treatment applications. In this study, a semi-batch reactor has been used to treat EDCs with ozone. Ozone has been bubbled into the reactor using a ceramic porous sparger (Pirex 2). Diclofenac sodium (DFS), caffeine (CBZ) and diethyl phthalate (DEP) were selected as target compounds to represent phthalates and pharmaceutical EDCs. Experiment and modeling were carried out to study the semi-batch reactor. Experiment was first conducted and used to validate the mathematical model. The model was then applied to investigate the effect of different operating parameters on the EDC and TOC removal efficiencies of the reactor.
