The effect of media configuration and internal recirculation on the system performance was studied. In the first experiment, three-UAFF reactors filled with different media, i.e., polypropylene beads, sponge cubes and coconut fiber were continuously fed with synthetic wastewater at upflow velocity of 0.04 m h-1. The COD removal efficiency in the reactor filled with sponge cubes was highest at 90%, whereas the others filled with polypropylene beads and coconut fibers with lower specific surface area were about 80%. In the second experiment, three-UAFF reactors with sponge were applied to treat real piggery wastewater. COD removal efficiencies were found to be about 80% and methane production rate of 0.26 l l r -1 d-1. The system performance could be slightly improved by 10% when applying internal recirculation. A sludge blanket (60-70% of total biomass) plays an important role in the system when applied to the treatment of piggery wastewater containing high suspended solid concentration. ？ 2007 Springer.
