Carlos, Nitrate(NO3) and ...
Carlos, Nitrate(NO3) and Nitrite(NO2) are both Anions and are removable by Anion Exchange Resin Specific for Nitrate/Nitrite removal. The media is regenerable with Softener Salt using the Negative Chlorine Ion's of the NaCl. Reverse Osmosis will also Remove approximately 76% of Nitrate/Nitrite, but is also more expensive initially and in operation costs. Also, once equipment is in operation, the water quality should be tested at regular intervals.
