Abstract:
Strong acid cation resins used alone or in combination with zeolite-based ion exchange resins are encapsulated in various water permeable polymer fabric bags of various geometries and thicknesses to reduce the calcium hardness levels during swimming pool and spa water fills. The resin bags are strategically placed in the pool or spa to allow water under pressure to flow through the ion exchange media to exchange calcium or magnesium ions with sodium or other harmless cations.
