AB  - Aeration phase length control and step-feed of wastewater are used to achieve 
      nitrogen removal from wastewater via nitrite in sequencing batch reactors (SBR). 
      Aeration is switched off as soon as ammonia oxidation is completed, which is 
      followed by the addition of a fraction of the wastewater that the SBR receives 
      over a cycle to facilitate denitrification. The end-point of ammonia oxidation is 
      detected from the on-line measured pH and oxygen uptake rate (OUR). The method 
      was implemented in an SBR achieving biological nitrogen and phosphorus removal 
      from anaerobically pre-treated abattoir wastewater. The degree of nitrite 
      accumulation during the aeration period was monitored along with the variation in 
      the nitrite oxidizing bacteria (NOB) population using fluorescence in situ 
      hybridization (FISH) techniques. It is demonstrated that the nitrite pathway 
      could be repeatedly and reliably achieved, which significantly reduced the carbon 
      requirement for nutrient removal. Model-based studies show that the establishment 
      of the nitrite pathway was primarily the result of a gradual reduction of the 
      amount of nitrite that is available to provide energy for the growth of NOB, 
      eventually leading to the elimination of NOB from the system.
