Abstract
Anaerobic digestion is widely used for the treatment of industrial wastewater for its cost benefits effects and potential production of renewable energy. Therefore, industries/industrial plants are installing and developing their wastewater treatment plant with this method for treating the discharged wastewater to get renewable energy source for the production of heat and electricity.
To investigate the evaluation of performance of the anaerobic digestion for industrial effluents, samples of dairy, oat processing and food processing industrial effluents were digested anaerobically with inoculum in lab experiment. It was showed that the highest COD: VS ratio was 2.08 for food processing industrial effluent which is the indication of higher... (More)
Anaerobic digestion is widely used for the treatment of industrial wastewater for its cost benefits effects and potential production of renewable energy. Therefore, industries/industrial plants are installing and developing their wastewater treatment plant with this method for treating the discharged wastewater to get renewable energy source for the production of heat and electricity.
To investigate the evaluation of performance of the anaerobic digestion for industrial effluents, samples of dairy, oat processing and food processing industrial effluents were digested anaerobically with inoculum in lab experiment. It was showed that the highest COD: VS ratio was 2.08 for food processing industrial effluent which is the indication of higher degradation of organic matters and higher methane production. The analysis of wastewaters compositions showed that components of pH values and C:N ratios are responsible for most of the inhibition of the anaerobic process.
The experiment was done by biomethane potential test for total 43 days of degradation. After the degradation, the highest accumulated methane potential among three of the samples was found from food processing wastewater to 0.55 L CH4/g VS. The potentials of total accumulated methane productions from dairy wastewater was obtained 0.48 L CH4/g VS and from oat processing wastewater 0.32 L CH4/g VS.

The estimated energy potential was found highest for food processing wastewater in summer when the industry discharges more wastewater compare the discharge in winter. The estimated energy potentials were found to be 3.7*106 kWh/year, 2.6*106 kWh/year and 4.3*105 kWh/year for food, dairy and oat processing wastewater respectively. (Less)
