Anaerobic co-digestion of agricultural solid waste, wastewater, and manure was evaluated in batch reactor. The performance of anaerobic digestion (AD) was monitored by assessing the methane production potential, maximum methane production rate and methane production lag time. An intermediate advanced oxidation processes by ozone was used to increase in the amount of methane produced and reduce the AD time. The production of methane from pure substrate (cow manure and wheat straw) was found to be 325 and 130 L/kg VS, mixed substrate of wheat straw, cattle manure and wastewater generated more than 368 L/kg VS. An intermediate ozonation process between two AD processes increased the % methane recovery form the ultimate value 60-85%, and reduce the total AD time to 20 days.Scopu
