Integrated photo-catalytic and anaerobic treatment of industrial wastewater for biogas production
Expanded Title:The aim of the project was to analyse the performance of the AD and AOP systems separately in degrading high strength wastes and to develop an integrated AD-AOP system to improve biogas production rate and methane yield. The treatment of high strength wastes such as molasses, textile, heavy metals and pharmaceutical was investigated under different experimental conditions. An Integrated AD and AOP using South African zeolite was applied in the treatment of methylene blue dye in up-flow fixed bed bioreactor and UV photoreactor. The optimal operating conditions obtained in the separate AOP and AD were applied in the treatment of methylene blue dye in an integrated up-flow fixed bed bioreactor and photoreactor. Results showed that, compared to the separate systems, the integrated AOP-AD system achieved better degradation with colour and COD reductions of 81% and 80%, respectively. Moreover, it was found that UV photodegradation pre-treatment improved the biodegradability of the MB dye by 3- folds after irradiation time of 60 minutes. Thus integration of the two processes in such a way that UV photodegradation precedes the AD process led to higher biogas production than that of the stand-alone AD process.
