Anaerobic Baffled Reactor ABR

With the latest development, split feed anaerobic baffled reactor (SFABR) was introduced and it shortened the start-up period and gave higher process performance (Uyanik et al., 2002), when using improved seed material, even for the treatment of particularly problematic wastewater, i.e. ice-cream wastewater. An SEM study revealed that granulation process occured rapidly in the SFABR compared with other reactor configurations, and that the reactor contained a highly mixed population of methanogens in all compartments. The use of polymer-conditioned anaerobic sludge and granular sludge as seed proved advantageous over the use of suspended growth anaerobic sludge, and the "improved" SFABR consequently performed more efficiently and also showed greater stability than the conventional ABR.
