Impact on nitrifiers of full-scale bioaugmentation

What is it about?

Bioaugmentation can be used to enhance nitrification in the activated sludge process. Nitrifiers from a side-stream plant can be inoculated to the mainstream process, which is thereby boosted. The study reveals how bioaugmentation increases the diversity of nitrifiers in the mainstream process and in the side-stream plant; that the abundance of nitrifiers is increased in the mainstream process; the interaction between nitrifiers from the side-stream plant and mainstream process; and the effect of bioaugmentation on nitrifying genera and species over time. This detailed microbial information on nitrifying species during a full-scale bioaugmentation study has not been presented before.
