... at constant conditions. The microbial composition was investigated over a period of 6 months using fluorescence in situ hybridization (FISH) to identify key microbial groups. Nitrification rate measurements confirmed the presence and activity of aerobic nitrifying populations. The FISH analysis demonstrated...

...Aotian Xu; Stephanie Young; Yanqiu Zhang A single-sludge step-feed anoxic–aerobic process (SSFAOP), characterized by enhanced nitrogen reduction performance, long solids retention time (SRT), and short aerobic hydraulic retention time (HRT), was designed to optimize nitrification...

...Baikun Li; Shannon Irvin; Katherine Baker The purpose of this study was to correlate the population size of ammonia-oxidizing bacteria (AOB) and nitrite oxidizing bacteria (NOB) with nitrification performance under various operational conditions (chemical oxygen demand (COD) concentration...

... FBAR. Le FBAR de sulfatoréduction élimine aussi les métaux et les métalloïdes toxiques présents dans le concentré de saumure grâce à une combinaison de précipitation des sulfures et la sorption sur des sulfures de fer. reverse osmosis nitrification denitrification brine concentrate fluidized...

...Baikun Li; Shannon Irvin Nitrogen dissimilation (nitrification and denitrification) and assimilation (uptake by cell growth) under different operational conditions (chemical oxygen demand (COD) and dissolved oxygen (DO)) were evaluated in a sequencing batch reactor (SBR) system. Nitrogen...
