Data obtained for publication J. Wat. Proc. Eng. 62, 2024, 105397<b>Authors and Affiliations</b>Adam Kubiak and Michał Cegłowski from the Faculty of Chemistry at Adam Mickiewicz University, Poznań, Poland.<b>Data Collection Dates</b>Tests under real-world conditions at an operational sewage treatment plant were conducted in <b>February 2024</b>.<b>Methodology and Tools</b>The study involved fabricating a <b>titanium dioxide (</b><b>T</b><b>i</b><b>O</b><b>2</b><b>​</b><b>) loaded carbon fiber photocatalyst</b> using a hydrothermal process. The material's properties were analyzed using a comprehensive suite of methods including XRD, SEM, TEM, XPS, and Raman spectroscopy. The experiment was centered around a novel <b>batch-flow photocatalytic system</b> equipped with a custom <b>LED light source</b> (emitting at 365, 380, 390, and 410 nm). The entire setup, including the photoreactor and a recirculation pump, was sustainably powered by a <b>200W photovoltaic panel</b> and a 26 Ah AGM gel battery. Diclofenac concentrations were quantified using an <b>HPLC system</b>, while its degradation byproducts were identified with <b>ESI-MS analysis</b>.<b>Funding Information</b>This work was funded by the <b>National Science Centre of Poland</b>, project number <b>2021/43/D/ST5/01190</b>.
