A nitrogen removal rate of 89% on average was achieved at the end of the study with the influent total nitrogen concentration of 2200 mg l<sup>-1</sup>. The nitrogen-loading rate (NLR) of 17 kg N/(m<sup>3</sup>×d) was achieved in the PNBS, and a reduced NLR of 6 kg N/(m<sup>3</sup>×d) was maintained in the GAP. To our knowledge, this is the highest NLR applied to a two-stage anammox system. A genetic analysis of the sludge samples revealed that a <em>Nitrosomonas</em><em> sp.</em> was enriched in the PNBS reactor, while, <em>Kuenenia stuttgartiensis</em><sub>,</sub><em> Uncultured bacterium clone KIST-JJY001</em>, and <em>Uncultured anoxic sludge bacterium KU2</em> were enriched in the GAP reactor.</p> </p></abstract><publication_date><month>11</month><day>10</day><year>2016</year></publication_date><pages><first_page>867</first_page><last_page>874</last_page></pages><publisher_item><identifier id_type="pii">gnest_02048</identifier></publisher_item><doi_data><doi>10.30955/gnj.002048</doi><timestamp>1714165527</timestamp><resource>https://journal.gnest.org/publication/gnest_02048</resource></doi_data></journal_article></journal></body></doi_batch> </div>
