Outline of Final Research Achievements

A novel rotating advanced oxidation contactor (RAOC) was developed for removing pharmaceuticals in aquaculture wastewater. Powdered TiO2/zeolite composites were firstly synthesized by sol-gel method and applied for the removal of sulfamonomethoxine (SMM) in fresh aquaculture wastewater (FAWW). The composites adsorbed SMM and thereafter decomposed it by photocatalysis, indicating they can effectively remove SMM in FAWW. Then, the TiO2-zeolite composite sheet was prepared and attached on both sides of a stainless steel disk. The disk was applied for a laboratory-scale rotating advanced oxidation contactor. The top half of the disk exposed to air was irradiated with ultraviolet irradiation, while the bottom half was submerged in water for adsorption. The SMM in distilled water was effectively adsorbed and decomposed by the RAOC, and mathematical model for the reaction was developed. In addition, the RAOC successfully removed SMM even in FAWW containing various coexisting materials.
