Reduce nitrate contamination from drinking water by developing a prototype electrochemical packed bed granular activated carbon (GAC) reactor that relies on the electrochemical transformation of nitrate on the surface of GAC in a packed-bed system.
The NiTreat team’s objective is to reduce nitrate contamination from drinking water by developing an electrochemical packed bed granular activated carbon (GAC) reactor. The continual increase of nitrate concentrations in drinking water has been linked to certain types of cancers, thyroid disorders and blue-baby syndrome. The filtration prototype has the potential to generate safer drinking water for communities impacted by high levels of nitrates in their drinking water. The long-term goal of the NiTreat team is to develop a flexible and scalable treatment technology with the potential for both water treatment facilities as well as small-scale point of use applications.
The team proposes a cost-effective filtration prototype that relies on the electrochemical transformation of nitrate on the surface of GAC in a packed bed system. This novel design has the potential to minimize the cost and waste streams associated with current treatment technologies, such as ion exchange. The development of this filtration prototype will include of optimizing the nitrate removal process, understanding the potential cost of the treatment, and the design and construction of an operational treatment unit.
By the end of the project period, the team is expected to have constructed a low-cost operational filtration prototype capable of significantly reducing nitrate concentrations in drinking water. The team will perform a cost-analysis data after optimizing different system parameters, as well as a sustainability analysis for the long term performance of the system.
