Because the HOCl is produced inside the reactor, no chemicals are handled during the treatment process. Additionally, our electrochemical reactor limits the concentration discharged from each cell to less than 1% NaOCl, which is below the EPA published safety standard. In fact, HOCl is produced naturally in the human body from white blood cells and is what protects the body from infections and harmful microbial bacteria.
The conversion is called Breakpoint Chlorination. The effect is caused by adding free chlorine at a concentration of 7.6 times the concentration of ammonia present in the water. However, higher multiples are often needed to reach breakpoint chlorination due to other chemistry in the water that demands oxidation ahead of ammonia oxidation. Typical dosages of 8-10 times ammonia concentrations are needed.
Each reactor cell produces about 2,000 mg/liter of NaOCl in optimal conditions of conductivity and chloride concentrations. The power to produce this is approximately 4.5kW/kg of NaOCl. Multiple cells can be configured to scale up the amount of NaOCl needed for any ammonia/nitrogen concentrations and to handle any water volume requirements.
In most applications the reactors are designed for long life and as such maintain a guarantee against defective parts for 18 months and for 5 years on the proprietary MMO electrode coatings. Depending on the specific application and chemicals present in the process water, actual coverage may vary, primarily due to potential degradation of the electrode coating under certain extreme environments.
