This paper reports on upscaling of a new technology combining solar photo-Fenton and aerobic biological processes to successfully treat a saline industrial wastewater containing around 600 mg L -1 of a non-biodegradable compound (R-methylphenylglycine, MPG) and dissolved organic carbon (DOC) of between 400 and 600 mg L -1 . Pilot-plant tests were used in designing this demonstration hybrid solar photocatalyticbiological plant with a 4 m 3 daily treatment capacity. It consists of a solar photo-Fenton reactor with 100 m 2 of solar compound parabolic collectors (CPCs) and an aerobic biological treatment plant based on an immobilized-biomass activated-sludge reactor (1 m 3 ). The catalyst concentration was Fe 2+ ) 20 mg L -1 . The overall efficiency in the combined system was around 95% mineralization. 50% of the initial DOC was degraded in the photo-Fenton pretreatment, and 45% was removed in the aerobic biological treatment.
