Dynamic Duo
Dynamic Duo provides heterotrophic and autotrophic nitrifying bacteria that reduce ammonia into nitrate and nitrite. It also supplements high concentrations of autotrophic ammonia-oxidizing and nitrite-oxidizing bacteria, such as Nitrospora, Nitrosomonas, Nitrospira, and Nitrobacter, to then convert nitrate and nitrite into non-detect forms of nitrogen.
Heterotrophic Bacteria for Ammonia Removal: Utilizes both carbon and nitrogen to consume nitrate and nitrite.
Autotrophic Bacteria for Nitrogen Oxidation: Includes high concentrations of ammonia-oxidizing and nitrite-oxidizing bacteria for complete ammonia removal.
Micronutrient-Enhanced: Contains a micronutrient blend that supports the growth and reproduction of nitrifying bacteria.

Product Details
Fast-Acting Ammonia Removal and Nitrifier Support
Dynamic Duo is a powerful two-part treatment designed to accelerate ammonia removal and restore healthy nitrification in municipal and industrial wastewater treatment systems. This combination of nitrifier bacteria and biostimulants provides immediate and sustained support for systems struggling with high ammonia levels, toxic shocks, or seasonal disruptions.
The first component delivers a high concentration of fast-starting Nitrosomonas and Nitrobacter species—key players in the ammonia-to-nitrate conversion process. The second part includes a proprietary biostimulant blend that enhances bacterial attachment, activity, and resistance to environmental stressors. Together, they work to quickly rebuild a stable nitrifier population and restore full treatment capacity.
Dynamic Duo is ideal for use after upsets caused by toxicity, hydraulic overload, or low dissolved oxygen, as well as during seasonal transitions when cold temperatures slow microbial activity. It can be applied directly to aeration basins, oxidation ditches, or biofilters, and is safe for use in any biological nutrient removal (BNR) or conventional activated sludge system.
When consistent ammonia reduction, reliable nitrification, and resilient biomass performance matter, Dynamic Duo delivers fast results and long-term stability.

Case Studies
Municipal Plant
Challenge
A Virginia Beach wastewater authority operates a 50 MGD wastewater treatment plant, and from time to time their plant struggles with nitrification.
Solution
As you can see from the chart below, the addition of VitaStim Dymanic Duo turns the plant around fast.
Results
Within 3 days the ammonia levels were in compliance. See Graph in New Window
Sugar Processing Plant
Challenge
A sugar processing facility in Minnesota lost nitrification in its aerobic tanks. This facility has a 1 MGD flow rate, their basin is 2 MGD, and the ammonia level was at 189 ppm.
Solution
They ordered 9 gal of VitaStim Nitrifiers and 9 gal of VitaStim Ammonia Assimilators. Then added 4 gal of each product initially and then added 1 gal per day thereafter.
Results
4 Days Later: The effluent ammonia had lowered to 17.2 ppm “It was like magic.” – Dr. David Rein, PhD, PE, Rein & Associates
Hog Slaughter Facility
Challenge
This industry is a hog slaughter facility with two anaerobic lagoons followed by an activated sludge process with a large 1.8-million-gallon aeration tank with a 2-day hydraulic retention time (900,000 GPD flow). Wastewater entering the aeration tank contains low levels of BOD (30-40 ppm typically), but high ammonia levels (200 ppm incoming ammonia). Alkalinity in this system occasionally gets as low as 50 ppm, but usually is 120 ppm. Ammonia in the aeration effluent is typically below one ppm, with nitrite levels below detection limits. In early October, this plant experienced heavier than typical loading which led to a pH drop to 6. In addition, a mistake occurred in which a wasting pump was left on for 24 hours, leading to significant loss of solids. Initially ammonia spiked up to 5.86 ppm but returned to normal within a day without treatment. However, nitrite levels in the basin progressed to around 45 ppm before treatment occurred.
Solution
This facility added 2 gallons of Dynamic Duo initially, and after 1 day their nitrite levels to decrease to 7.7 ppm. A temperature shift occurred in the system the following night which led to the nitrite levels in the system increasing back to 32 ppm. As treatment continued, nitrite levels returned to 7.5 ppm after 1 more day of treatment recovered to 0.199 ppm nitrite in effluent after 3 more days.
