Wan C.Yang X.Lee D.-J.Liu X.Sun S.2019-05-142019-05-14201418761070https://scholars.lib.ntu.edu.tw/handle/123456789/407959Partial nitrification on ammonia laden wastewater using aerobic granule continuous-flow reactors was studied. Effects of temperature and carbon sources on performance of partial nitrification and characteristics of aerobic granules were reported. High nitrite accumulation ratio (>90%) was observed in all reactors after an acclimation phase of 6 days. Decrease in temperature or inorganic carbon concentration limited nitrite accumulation ratio; while nitrite accumulation was hard to recover once complete nitrification to nitrate was established in granules. The aerobic granules collected at continuous-flow reactor were stronger in strength than the seed granules from sequential batch reactor. Clone libraries revealed that Nitrosomonas europaea and Nitrosomonas sp. were the ammonia-oxidizing bacteria (AOB), whereas Nitrobacter sp. and Nitrospira cf. moscoviensis were nitrite-oxidizing bacteria (NOB). Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analysis revealed that temperature and carbon sources shifted the microbial community in granules. ? 2014 Taiwan Institute of Chemical Engineers.Aerobic granulesClone libraryContinuous-flowPartial nitrificationPCR-DGGE[SDGs]SDG6journal article10.1016/j.jtice.2014.08.0092-s2.0-85027931021https://www.scopus.com/inward/record.uri?eid=2-s2.0-85027931021&doi=10.1016%2fj.jtice.2014.08.009&partnerID=40&md5=66d05229e6f60d290345b7636560d520
