Effect of Ferrous and Nitrate Ions on Biological Hydrogen Production from Dairy Effluent with Anaerobic Waste Water Treatment Process

Jai Shankar Paul, A. Quraishi, Veena Thakur and S.K. Jadhav    

Abstract: Biohydrogen is a clean and environmental friendly renewable energy source. It only produces water after combustion. Anaerobic fermentation process is one of the best suitable technique for the biohydrogen production from industrial wastes. In this study with the consortium of biohydrogen producing bacteria B1 and B4 at the pH 5 and temperature 70°C, the effect of different concentration of ferrous and nitrate ions in the production of biohydrogen from dairy effluent was analyzed. Maximum biohydrogen production at the concentration of 100 mg L-1 of ferrous ion during 24 h HRT (Hydraulic Retention Time) was 55 mL with HPR (Hydrogen Production Rate) of 5.729 mL L-1 h-1 and during 48 h HRT 85 mL of biohydrogen was produced with the HPR of 4.427 mL L-1 h-1. This process has been found to be an efficient method for the treatment of effluent in different pollution parameters after this fermentative biohydrogen production.
