The production of hydrogen from organic contaminants was studied on batch and continuous scales. On the batch scale, three important operational parameters namely; organic loading, pH and inoculum concentration were varied to find the optimum values for increased hydrogen production. The hydrogen yields increased from 1.7 mole H2/mole glucose to 2.3 mole H2/mole glucose when substrate concentration was decreased from 10 g/L to 2.5 g/L. Decreasing the organic loading decreased the production of volatile acids and kept the pH relatively stable. The hydrogen yields were lower at a pH of 4.5 at 1.2 mole H2/mole glucose compared to 2 mole H2/mole glucose at a pH of 5.5. Hydrogen content in the biogas increased with the increased inoculum concentration. The hydrogen yields in continuous reactors increased with decreased organic loading and were higher than that of batch reactors at 2.6 mole H2/mole glucose. Total removal of organic contaminants was achieved in both batch and continuous reactors.
