For the phosphorus recovery from the excess sludge in the sewage treatment process, the decomposition of excess sludge by using ozone micro-bubbles was focused, and the influence of ozone micro-bubble on the foam behavior and the decomposition performance was examined. A cocurrent upflow bubble column with micro-bubble generator was used and the excess activated sludge was decomposed under the various conditions. The foam behavior was observed and the decomposition performance was measured.<BR>The foam behavior was quite different with the bubble size. When ozone micro-bubbles were dispersed, the ozone decomposition was much enhanced. As a result, the decomposition time and required amount of ozone became much lower than those in the case of milli-bubbles.
