The Veolia ANITA Mox moving bed biofilm reactor from Kruger USA can be used to treat wastewater streams with high ammonia concentrations. Sidestreams from dewatering of anaerobically digested sludge are well-suited for the process. It can remove nitrogen from streams with only 40 percent of the aeration demand of conventional nitrification, and without supplemental carbon. This saves operating costs and reduces ammonia load and load swings on the main plant. A continuous aeration control method creates the necessary conditions for ammonia oxidizing bacteria and anammox bacteria to operate simultaneously in the biofilm of a single-stage reactor. 919/677-8310;
