Ion exchange nitrate removal
WebHard water can be softened using an ion exchange softening process (SKIPTON 2008). Ion exchange processes can also remove various charged atoms or molecules (ions) such as nitrates, fluoride, sulphates, perchlorate, iron and manganese ions as well as toxic metals (radium, uranium, chromium, etc.) from water.
