ANITA Mox sidestream deammonification technology consists of AnoxKaldnes K5 Media engineered polyethylene carriers from Kruger USA to provide ample protected surface area for biofilm to thrive. The media (approximately the diameter of a quarter) hosts two types of bacteria in the same reactor. The outer layer consists primarily of ammonia-oxidizing bacteria, which converts about half of the ammonia to nitrite. The inner layer consists mainly of anammox (anaerobic autotrophic ammonia oxidizer) bacteria. These bacteria use the resulting nitrite and much of the remaining residual ammonia and convert them to nitrogen gas, which is released harmlessly to the atmosphere. 919/677-8310; www.veoliawatertech.com
