ResinTech manufactures several nitrate selective ion exchange products based on higher amine functionalities and also provides standard Type I and type II strong base anion resins that can be used for nitrate removal.
Although all strong base anion resins prefer nitrate over chloride, at TDS suitable for potable water, the standard type I and type II resins prefer sulfate over nitrate. This preference can result in dumping nitrates, a condition where the resin adds nitrate to the finished water instead of removing it.
ResinTech’s nitrate selective resins have increased selectivity for nitrate and prefer nitrate over sulfate and other anions, even at very low TDS. This increased preference prevents nitrate dumping. In waters that have high sulfate concentrations nitrate selective resins also enjoy higher operating capacities than can be obtained from the standard type I and type II anion resins.
As with all other products intended for potable water, all of ResinTech’s nitrate selective resins as well as our standard type I and type II strong base anion resins are WQA Gold Seal approved and meet the NSF/ANSI 61 standard for drinking water.
