Process and nitrate plant for removing nitrates from drinking water

摘要

The invention relates to a process for removing nitrates from drinking water in an ion exchanger, according to which in the course of charging an exchanger substance, the nitrate ions present in the untreated water are exchanged for hydrogen carbonate ions and after charging has been completed, the exchanger substance is regenerated. The exchanger substance is regenerated by a saturated sodium bicarbonate solution in order to achieve an economical and hygienically faultless drinking water treatment. IMAGE
