On contrary, there is a dire need for greener processes to increase clean potable water and bio-fuels. This study purposed to electrolyze bio-slurry for its purification while producing bio-hydrogen gas. An electrolytic biomass solar cell (EBSC) of capacity 4,000ml and current density 3.458amps/cm2 was used. Carbon and steel wool were used as the anode and cathode respectively. The levels of physico-chemicals and bacteria inhibition in the bio-slurry were monitored over a 24-day retention period. Functional groups in the bio-slurry were observed before and after electrolysis while the volumes of bio-hydrogen gas were also monitored. Solid matters in the bio-slurry were effectively reduced by 32.15% while turbidity decreased from 18.92 to 6.85 NTU. The pH value decreased from 8.5 to 6.5 with the electrolysis process. Removal of E. coli bacteria was significantly higher than that of S. aureus (P > 0.05). There were observable changes in the functional groups of the raw and electrolyzed samples, corresponding to the changes in compounds and pH decline. The highest volume of bio-hydrogen recorded was 450.0ml. Bio-hydrogen gas production was largely affected by the temperature and decreased over the retention period.
