|a Azo dyes, common in textile wastewater, have high photolytic and chemical stabilities, which make them difficult to be removed using conventional treatments. This study aims to evaluate a combined process using heterogeneous photocatalysis, with ZnO/UV or TiO2 /UV (0.6 g catalyst L-1 solution/2-hr UV radiation), and a biological process for textile wastewater treatment. After the proposed treatments, the color and organic matter removals from synthetic wastewater (SW) and industrial wastewater (IW) were evaluated. For SW, the coupled photocatalytic (ZnO/UV or TiO2 /UV)-biological system promoted a high extent of color removal (98%) and total organic carbon (TOC) reduction (>80%). Promising results were obtained with IW using combined photocatalytic (TiO2 /UV)-biological treatments, reaching 97% and 63% of color and TOC removal, respectively. This process, coupling heterogeneous photocatalysis and a bioprocess, has proved to be a good alternative for the treatment of textile wastewater, not only for color removal but also for dye mineralization purposes. PRACTITIONER POINTS: A combined process using heterogeneous photocatalysis (ZnO/UV or TiO2 /UV) and biological process was evaluated for synthetic (SW) and industrial (IW) textile wastewaters treatment. For SW, coupled process promoted high extent of colour and organic matter removals. For IW, promising results were obtained with TiO2 /UV-biological treatment (97% of colour and 63% of organic matter removals)
