This study focused on the treatment performance of membrane bioreactor (MBR) coupled with intermittent ozone bubbling for the effective recovery of dissolved organics from coagulated fresh sewage sludge. Intermittent ozone bubbling was effective in the prevention of permeation resistance increase caused by particle accumulation on membrane surface, which result in keeping high permeation flux. MBR with intermittent ozone bubbling is believed to be an effective system for the recovery of organic matter usefully utilized in biological denitrification as well as membrane fouling reduction.
