VitaStim Dynamic Duo

Full Recovery in 10 Days or Less

Nitrification can quickly drop from toxicity or cold conditions. For the fastest recovery and to remove ammonia we’ve developed the Dynamic Duo, VitaStim Nitrifiers and Ammonia Assimilators to quickly remove ammonia and bring nitrification right back. This product is for use in aerobic wastewater treatment plants.

VitaStim Nitrifiers contains high concentrations of autotrophic ammonia- and nitrite-oxidizing bacteria, such as Nitrospora, Nitrosomonas, Nitrospira, and Nitrobacter as well as a micronutrient helpful to the growth and reproduction of nitrifying bacteria.

VitaStim Ammonia Assimilators contains heterotrophic nitrifying bacteria that utilize both carbon and a high fraction of nitrogen. In systems with high organic loading or low dissolved oxygen the Ammonia Assimilators are the first step in removing ammonia from wastewater.
