One of the operational challenges for the system was to cope with the large fluctuations of the ROC flow. This study investigated the decay rates of ammonia-oxidizing bacteria (AOB) and nitrite-oxidizing bacteria (NOB) and biofilm detachment in MBBR during starvation for up to one month. An intermittent aeration strategy of 15 min aeration every 6 h was applied. This study also evaluated the activity recovery of both AOB and NOB after normal operation was resumed. The results showed that the activity loss of AOB and NOB was relatively minor (&amp;lt;20%) within 10 days of starvation, which ensured relatively quick recovery of ammonium removal when normal operation resumed. In contrast, the AOB and NOB activity loss reached 60\u201380% when the starvation time was longer than 20 days, resulting in slower recovery of ammonium removal after starvation. Starvation for less than 20 days didn't result in an apparent biomass detachment from carriers.<\/jats:p>","DOI":"10.2166\/wst.2012.252","type":"journal-article","created":{"date-parts":[[2012,7,6]],"date-time":"2012-07-06T09:31:10Z","timestamp":1341567070000},"page":"837-842","update-policy":"http:\/\/dx.doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":3,"title":["Evaluating a strategy for maintaining nitrifier activity during long-term starvation in a moving bed biofilm reactor (MBBR) treating reverse osmosis concentrate"],"prefix":"10.2166","volume":"66","author":[{"given":"Liu","family":"Ye","sequence":"first","affiliation":[{"name":"Advanced Water Management Centre (AWMC), The University of Queensland, St Lucia, Brisbane, QLD 4072, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shihu","family":"Hu","sequence":"first","affiliation":[{"name":"Advanced Water Management Centre (AWMC), The University of Queensland, St Lucia, Brisbane, QLD 4072, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yvan","family":"Poussade","sequence":"first","affiliation":[{"name":"Veolia Water Australia, Level 15, 127 Creek Street, Brisbane, QLD 4000, Australia and Seqwater, 240 Margaret Street, Brisbane, QLD 4000, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jurg","family":"Keller","sequence":"first","affiliation":[{"name":"Advanced Water Management Centre (AWMC), The University of Queensland, St Lucia, Brisbane, QLD 4072, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhiguo","family":"Yuan","sequence":"first","affiliation":[{"name":"Advanced Water Management Centre (AWMC), The University of Queensland, St Lucia, Brisbane, QLD 4072, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","container-title":["Water Science and Technology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/66\/4\/837\/443177\/837.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/66\/4\/837\/443177\/837.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,28]],"date-time":"2020-03-28T00:44:21Z","timestamp":1585356261000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/wst\/article\/66\/4\/837\/16348\/Evaluating-a-strategy-for-maintaining-nitrifier"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,8,1]]},"references-count":0,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2012,8,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wst.2012.252","relation":{},"ISSN":["0273-1223","1996-9732"],"issn-type":[{"value":"0273-1223","type":"print"},{"value":"1996-9732","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2012,8,1]]},"published":{"date-parts":[[2012,8,1]]}}}
