Removal of Ammonia can be a difficult process, but it is critical to maintaining a healthy wastewater treatment plant.

Upsets can be caused by several external factors such as shock loading, toxicity and solids loss. The microbes that have been isolated for EnviroDEFENSE® AmmoniaFixerTM will efficiently degrade the Ammonia, survive in harsh conditions and react quickly after nitrification disruptions.

EnviroDEFENSE® AmmoniaFixerTM is a fast and effective biological solution for nitrification. EnviroDEFENSE® AmmoniaFixerTM is a proprietary nitrification product formulated for a variety of wastewater types. The microorganisms in EnviroDEFENSE® AmmoniaFixerTM thrive in a wide range of wastewater types and respond quickly during upset conditions to restore balance.
