ion exchange
Let an agent explain ion exchange, relay how it works, its materials and its uses from chemistry sources, and distinguish it from filtration and from distillation.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain ion exchange, relay how it works, its materials and its uses from chemistry sources, and distinguish it from filtration and from distillation.
Ion exchange is a process in which ions dissolved in a liquid are swapped for other ions held on a solid material, typically a resin, without the solid dissolving; the registry alias names resin regeneration service. It is widely used to soften and purify water, remove unwanted ions and recover valuable ones, and the exchange material can be recharged. This is a chemistry topic described at a general level.
What it is for: Swapping ions between a liquid and a solid.
It can be explain the process; relay materials and uses; note regeneration; distinguish it from filtration.
Distinguishing features
Exchanges ions
Uses a solid resin
Resin can be recharged
Purifies and softens water
What it looks like
Not a single appearance; a liquid passing through beds of exchange resin beads.
Physical character
swaps: dissolved ions note
medium: ion-exchange resin note
registry parent: transformation note
How it is recognised
Swapping of ions between liquid and a solid resin
Ion-exchange resin regeneration service
Filtration removes particles; distillation separates by boiling
