High concentrations of ammonia in effluent present a continuing problem for municipal wastewater plants and many industrial facilities. World Water Works’ conDEA™ process can solve the problem. It is a patented and patent pending biological process used to remove nitrogen from wastewaters containing high ammonia concentrations (>200 mg/L). Unlike the traditional expensive nitrification-denitrification method for removing nitrogen which requires large amounts of energy and methanol, the conDEA process uses ammonia oxidizing bacteria (AOB) and anaerobic ammonium oxidizing bacteria (Anammox) to efficiently and reliably remove ammonia from wastewater. This is the process of deammonification which uses 60 percent less energy, completely eliminates the need for methanol, and produces 90 percent less sludge than traditional systems. This reduces costs and is very environmentally friendly – the anammox based conDEA process features a low carbon footprint since it sequesters carbon dioxide. This anammox based process was developed and patented by the University of Innsbruck, Austria. The true key to World Water Works’ success is conDEA’s patented control strategy and patent pending biomass separation device, which maintains appropriate levels of both AOB and Anammox bacteria. The biomass separation device decouples the SRT to allow for two very different bacteria – AOBs and Anammox to thrive. This provides great system resilience and lessens the need for oversight and maintenance. This process is operated in a continuous mode of operation.
