Abstract

The aim of this work was to study along of different cycles the biomass adaptation process to total polyphenols (TPP) concentrations in an Anaerobic Sequencing Batch Reactor (AnSBR) and to evaluate the degradation of TPP and COD in winery wastewater (WWW). A lab-scale AnSBR was operated at 30º C with intermittent stirring and was fed with WWW with a COD of 182.25 g/l and a TPP concentration of 489 mg/l. The AnSBR was operated in four cycles, after the first cycle the biomass adaptation was taken for granted since reductions in the TPP went from 56% in C1 to around 95% in the consecutive cycles. COD reduction reached the 95% to 99% for all the four cycles.
