Direct Nitrate Conversion to Gaseous Nitrogen
The NitrEL system is an electrochemical water treatment process that reduces nitrate concentrations in contaminated drinking water, groundwater and industrial process wastewater streams by converting the nitrate directly to environmentally friendly N2 gas.
NitrEL has been designed for in situ and ex situ applications. The in situ
system utilizes a "fence" of electrodes inserted into the contaminated
aquifer. Conversion of dissolved nitrate to gaseous nitrogen occurs as nitrate-laden
groundwater passes through the fence.
For ex situ applications, the NitrEL system is often used in combination with the DesEL system to treat the concentrate stream.
Unlike biological de-nitrification, the NitrEL system offers constant rates of de-nitrification that are not affected by acidity, aeration, temperature or nutrient availability.
The NitrEL system is capable of removing above 90% of the nitrate from highly contaminated aquifers. In addition NitrEL has shown the added benefit of removing up to 70% of the dissolved ammonia.
Other advantages of the NitrEL System include:
- Operation and efficiency that are unaffected by temperature.
- Minimal monitoring and maintenance.
- Zero greenhouse gas emissions.
- Modular and adaptable to a variety of site conditions and nitrate concentrations.
