World-Water - Model DEMON - Anammox Treatment Technology - Brochure
DEMON anammox treatment technology reduces high-strength ammonia (NH3-N) levels in the reject flows from landfill leachate, industrial streams and dewatering centrate/filtrate from anaerobic digestion. From the specific streams, the treated water returns to the plant influent with up to 70-80% less total nitrogen (TN) loading. This is a continuous deammonification process, using granular, anaerobic ammonium oxidizing bacteria anammox biomass retained by micro-screens. Compared to traditional nitrification-denitrification methods, which require large amounts of energy (1.8-2.7 kW-hr/lb N), alkalinity and external carbon resources, DEMON uses both ammonia oxidizing bacteria (AOB) and anammox bacteria to efficiently (0.45-0.79 kW-hr/lb N) and reliably remove ammonia and total nitrogen.
