Page 1 Ion Exchange units are known primarily as watersofteners. But they can also remove nitrates, sul-fates, and various toxic metals from water. Under-standing how ion Exchange works and what contami-nants different units will remove can help you makeinformed decisions about water treatment by Ion Exchange Works Ions are atoms, small particles that are the build-ing blocks for molecules. Ions have a weak electricalcharge. The charge may be positive (for cations) ornegative (for anions ). This positive and negativecharge is similar to the north or south pole of a mag-net or the positive or negative terminal of a car charged sodium ions are commonlyused to coat Cation Exchange resins.
