title = "Factors influencing enrichment of anammox bacteria in baffled biofilters",
abstract = "Anaerobic ammonium oxidation (anammox) is a shortcut for biological nitrogen removal which requires less oxygen and generates less biosolids. Two baffled biofilters packed with marble chips and mini marble chips respectively were operated to diagnose the factors influencing anammox enrichment. Both of the biofilters had anaerobic conditions (dissolved oxygen <0.3 mg L -1) and slight alkaline pH (7.24-7.99), which were suitable for anammox. Mass balance analysis suggested coexistence of nitrification and anammox. Scanning electron microscopic images showed thin biofilms attached to the marble chips. A lower nitrite concentration (≤8.6 mg N L-1) and short hydraulic retention time (≤2 d) were found to be favorable for enrichment of anammox in the passive baffled biofilters.",
