Guatapé (Medellín), Colombiahttp://hdl.handle.net/10198/21108Solar hardware design for photocatalytic processes includes aspects of optics, geometry and reactor materials. Compound parabolic collectors (CPCs) have widely been used to promote heterogeneous and homogeneous photocatalytic reactions. In this work, different reflective surface (RS) materials (anodized aluminum with [MS] and without [R85] protective coating, soiled aluminum [R85s] and stainless steel [SS]) and geometries (flat [F], single piece-double parabola [SP] and two pieces-double parabola [DP]) were tested aiming the degradation of a recalcitrant organic compound, gatifloxacin (GAT), by using a heterogeneous TiO2 photocatalytic system. Firstly, the photonic flux entering the system was measured by 2-nitrobenzaldehyde actinometry, considering the different RSs. After that, the catalyst (TiO2-P25) was immobilized in the surface of a static mixer and axially inserted in the tubular borosilicate photoreactor. Finally, the efficiency of the heterogeneous photocatalytic system was evaluated for GAT removal from aqueous solution using the best photoreactor configuration.engSolar collectorsHeterogeneous photocatalytic processAdvanced oxidation processconference object
