Project description
The overall objective of this study was to investigate the principles and kinetics of the AnSBR process so that optimum design and operational parameters for efficient and stable treatment can be determined. The main objective was to acquire data that could be used to generate prediction models of the anaerobic digestion of winery wastewater processes and subsequently
enable predictions to be made as to the treatability of the winery wastewater by AnSBR.
Two different approaches were followed. The first involved monitoring certain parameters, such as COD, pH, conductivity, temperature, Oxidation-Reduction Potential (ORP) and gas production throughout the digestion cycle so as to use these values in the ADM 1. The second approach involved using a statistical central composite design to determine the effect of pH, feeding regime and mixing rate on the performance of the AnSBR, by monitoring COD reduction, influent and effluent pH, volatile fatty acids, alkalinity, polyphenol reduction, temperature and the VFA: alkalinity ratio.
