Impact on nitrifiers of full-scale bioaugmentation
(2017) In Water science and technology : a journal of the International Association on Water Pollution Research 76(11-12). p.3079-3085- Abstract
Nitrifiers are the slowest growing bacteria used in conventional biological wastewater treatment. Furthermore, their growth rate is seriously hampered by low temperature. As a result, the volume needed for nitrification dominates the volume of the biological reactors at a wastewater treatment plant. As a way of enhancing nitrification and reducing this volume, bioaugmentation can be used. Nitrifiers from a side-stream plant can be inoculated to the mainstream process, which is thereby boosted. The effect of bioaugmentation can be measured in different ways. This full-scale study focuses on the effect of bioaugmentation from a microbial point of view by using 16S rRNA amplicon sequencing. The study reveals how bioaugmentation increases... (More)
Nitrifiers are the slowest growing bacteria used in conventional biological wastewater treatment. Furthermore, their growth rate is seriously hampered by low temperature. As a result, the volume needed for nitrification dominates the volume of the biological reactors at a wastewater treatment plant. As a way of enhancing nitrification and reducing this volume, bioaugmentation can be used. Nitrifiers from a side-stream plant can be inoculated to the mainstream process, which is thereby boosted. The effect of bioaugmentation can be measured in different ways. This full-scale study focuses on the effect of bioaugmentation from a microbial point of view by using 16S rRNA amplicon sequencing. 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. To our knowledge, this detailed microbial information on nitrifying species during a full-scale bioaugmentation study has not been presented before.
