In this study, the effect of ozone addition to the aeration tank was investigated for both fixed-film and suspended-growth activated sludge processes. In the fixed-film process, ozone addition increased effluent SS concentration, indicating release of biomass from the carriers. In the suspended growth process, ozone addition improved settleability of activated sludge and hence effluent quality. Overall, the ozone activated sludge processes were demonstrated to improve BOD removal and to have no effect on the reduction of excess sludge production.
