Enhanced biological phosphate removal by granular sludge in a sequencing batch reactor

  title={Enhanced biological phosphate removal by granular sludge in a sequencing batch reactor},

  journal={Biotechnology Letters},
A laboratory-scale sequencing batch reactor was started-up with flocculated biomass and operated primarily for enhanced biological phosphate removal. Ten weeks after the start-up, gradual formation of granular sludge was observed. The compact biomass structure allowed halving the settling time, the initial reactor volume, and doubling the influent COD concentration. Continued operation confirmed the possibility of maintaining a stable granular biomass with a sludge volume index less than 40 ml… CONTINUE READING
