Research project: Hydrogen and methane production from wastewater with microbial granular sludge

Currently Active: 


Hydrogen production rate and yield from wastewater are too low to exercise in the practice. One of the causes is poor retention of the suspended sludge in the continuously operated reactor. In addition, fermentative hydrogen production alone cannot obtain the positive energy recovery as well as high COD removal efficiency. To overcome these constraints, hydrogen production followed by methane generation with high biomass retention in the reactor could allow the cost-effective wastewater treatment with clean energy production. This project aims to develop two-stage hydrogen and methane production process with microbial granular sludge, which is self-immobilized microorganisms without relying on any carrier media under certain conditions.
