Bioreactor Unit for Hydrogen Production from Palm Oil Mill Effluent



Several studies on biohydrogen production from POME have been accomplished using different reactors. The up flow anaerobic sludge blanket (UASB) reactor due to its ability to keep high microorganism concentration within and high rate of waste stabilization in the reactor, is an alternative bioreactor to generate biological hydrogen. The long start-up period, high and very low up-flow velocities and biomass washout at hydraulic stresses are the major problems associated with UASB reactors. Therefore, the UASB process modification is needed to eliminate the existing problems as well as having high-performance hydrogen production from POME. 

A combination of up-flow anaerobic sludge blanket (UASB) and up-flow fixed film (UFF) in a single reactor was invented as modified up-flow anaerobic sludge blanket-fixed film (UASB-FF) bioreactor to produce biohydrogen from POME. The fixed film (FF) packed at the top section make this bioreactor overwhelmed the recognized shortages of UASB and helps to retain a high concentration of biomass and prevents sludge washout in the reactor. The use of UASB-FF reactor was a good strategy to accelerate anaerobic granulation and to achieve a high COD removal efficiency as well as H2 yield in a short period of time. 

The advantages:

  • High Chemical Oxygen Demands (COD) Removal
  • Increase Production of Hydrogen with low amount of substrate in short period
  • Economical and effective treatment option for POME
  • Renewable resource for energy and materials
  • Cost Saving
  • Environment Protection
