This paper reviews the importance of phase separation in anaerobic wastewater treatment, characteristics of anaerobic baffled reactor (ABR), properties of anaerobic granular sludge, granulation process and advantages of granular sludge over nongranular sludge. The performance data of ABR and its modified configurations with regard to carbonaceous matter removal by using various seed sludges are compared. It is concluded that enhanced wastewater treatment efficiencies can be achieved with methanogenic granular seed sludge in an ABR because of a number of advantages associated with granular biomass over nongranular aggregates.
