Resumo: Abstract A Sequencing Batch Reactor (SBR) was combined with heterogeneous photocatalysis (TiO2/UV) as a tertiary treatment for a pencil manufacturer's wastewater. The SBR removed almost all Chemical Oxygen Demand (COD) from the wastewater, although color was barely removed. Photocatalysis was optimized using a factorial design. Final COD, Dissolved Organic Carbon (DOC), and color removals were 95%, 80%, and 93%, respectively. Treated wastewater showed no ecotoxicity towards Lactuca sativa. Color removal kinetics (photocatalysis) followed a pseudo-first order model. The SBR + AOP (Advanced Oxidation Process, TiO2/UV) combination was a feasibility choice for removing both COD and color from this wastewater.
