摘要

1. The OSCAR~® controller was successfully coupled with sludge ozonation process in two mid-scale WWTPs 2. Improved nitrogen removal efficiency was observed in both cases 3. The energy consumption for the bio-process was cut of 15 to 25% Sludge production was reduced of some 35% 4. Single-installation pay-back time: 5.4 and 7 years, but a shorter return on investment can be achieved on a basin-scale application of the OSCAR~® 5. Still to be clarified the actual effect of intermittent aeration on sludge reduction (in extremely under-loaded WWTP Y_(obs) dropped down of some 26%) 6. Further optimization by synchronizing anoxic phases with sludge ozonation.
