  • Bioaugmentation as a tool to accelerate the start-up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature

    Start up of anoxic-oxic process in a full-scale municipal wastewater treatment plant at low temperature was studied in this paper. Bioaugmentation technology was used to accelerate the start up. Aeration rate and feed style of influent were also controlled as associated measure to reduce the negative effect of low temperature on start up. The results showed that the process was successfully ...
