ISURF 05004 describes a two step method for the removal of nitrate from drinking water. This Technology utilizes an  electro-catalytic approach to initially reduce the nitrate to nitrite. The second step is the conversion of nitrite to volatile gases in a catalytic reactor. This two step approach is applicable for treating ground water.

The large and well established water treatment industry is experiencing increasing demands in water quality. This poses a special challenge in regions such as Iowa where agricultural runoff poses serious health and environmental concerns due to increased nitrate composition in groundwater. ISURF#05004 describes a reactor that allows for treatment of ground water for the reduction of nitrates and nitrites using a two-part approach. The first part involves the electrocatalytic reduction of nitrates to nitrites, the second part involves the use of chemical catalysis for the conversion of nitrites to volatile gases such as nitrogen.

The main drawback of current water purification processes such as reverse osmosis is high operating costs associated with waste removal. ISURF #05004 overcomes the limitations of these technologies by reducing nitrates to volatile gases, thus having a lower cost of waste removal. Initial studies of waste water have shown nearly complete reduction of the nitrate with only trace levels of nitrate and ammonium detected after first treatment.

• Electrocatalytic removal of nitrates and other reactive nitrogen species at a low cost with non-reactive products

• No secondary reactive species generated

• Minimal cost for removal of waste

• No additional /subsequent purification needed

Treatment of ground water in order to remove nitrates and nitrites which are of major health and environmental concern. Applications are high in areas such as Iowa where agriculture runoff prevails.
