Partial ozonation of returned sludge via high-concentration ozone to reduce excess sludge production: A pilot study

Partial ozonation of returned sludge via high and low concentration of ozone were compared to evaluate their efficiency in excess sludge production reduction. A pilot-scale system of anaerobic/anoxic/oxic (A/A/O) + ozonated sludge recycle (OSR) process was operated for 97 days, to investigate the ef...
