Two feeding strategies were compared for aerobic granular sludge SBR operation. Performance of split anaerobic–aerobic and dedicated anaerobic feeding was compared. Start-up, performance and microbial ecology were similar under both feed strategies. Aerobic granular sludge ecology was different to conventional activated sludge. Split anaerobic–aerobic feeding is a viable, cost-effective SBR retrofit solution.
