Reply To: How water softners work…?

[GaryPurolite1Participant]

“Catalyst” processes do not soften water. There are only 4 methods to truly soften water:
1. Cation ion exchange by ion exchange resins.
2. Reverse Osmosis – this is a hardness reducing process and typically is preceded by a process to prevent hardness fouling of the membrane.
3. Total water deionization – this includes a cation ion exchange resin.
4. Distillation – typically too expensive to use for water softening and also typically preceded by a cation ion exchange process.
