Upflow Anaerobic Sludge Blanket (UASB)
Can GSBRs be used effectively to further treat wastewater after a UASB process? (links with Aerobic GSBR team)
How effective are designs at capturing methane generated in UASB (minimizing losses in effluent and through leaks)
How robust are UASBs at handling rapid fluctuations in the strength of wastewater?
How well do the UASBs treat Nitrogen, phosphorus and, possibly, fecal indicator bacteria (harmless E.coli)?
How many households should be treated by a single UASB (ie. what is the ideal scale for the reactors - whole towns, small enclaves of ~10 homes, individual homes?)
How much energy can be produced per household reactor and how does this compare with cooking needs (cookstoves can use biogas directly)?
Methane co-generation (heat and electricity; will require generator)
- How sensitive are cultures to Oxygen stress and/or acid stress?
