Assessment of Carrot Juicing Pulp Hydrolysate fed MEC for Bio-Hydrogen production

The thrust for alternative renewable energy carrier with the integration of solid waste management and biofuel production is considering Biohydrogen as one of the most attractive alternatives. The present study aims to assess the suitability of carrot juicing pulp hydrolysate (CJPH) fed membrane less single chambered Microbial Electrolysis Cell (MEC) for the bio-hydrogen production in batch mode under applied voltage of 0.8 V at 30 ± 2 °C. The anode enrichment for bioanode with mixed culture of microorganism was achieved on heat treated graphite rods. The maximum bio-hydrogen production was reported as 0.1 m3 of H2/m3/d at Eapplied = 0.8 V at HRT of 21 days. The maximum COD removal of 76.6 % was reported. These results demonstrated an energy-efficient approach for biohydrogen production from CJPH coupled with waste mitigation.
