- •
Seeding EGSB reactors with heat treated anaerobic sludge led to consolidated granules.
- •
Upward liquid velocity (ULV) influences settling velocity and density of granules.
- •
Increasing ULV promoted bigger granules leading to greater biomass retention.
- •
ULV promoted selective wash-out of propionate-producing bacteria.
- •
ULV prompted granules development with increased specific hydrogenogenic activity.
