Nitrates removal

Nitrates level in drinking water is recommended below 50 mg/L, specially for babies. Indeed, their digestive systems are immature, and thus more likely to allow the reduction of nitrate to nitrite. The nitrite in the digestive tract of babies can cause methenoglobinemia.

Nitrates can be removed by ion exchange using strong anionic resin in Cl- form.
Reverse Osmosis is also efficient to remova nitrates, although the hydrophilic properties of the molecule does not allow an optimal removal.

Biological denitrification is used in municipal waste water treatment plant.

Lenntech can provide small and handy nitrate test-kits to test your water.
