How Water Softeners Work: Heat-Driven Ion Exchange Process Explained #98688 (License: Personal Use)

This schematic shows a water softener tank where incoming hard water is heated, causing dissolved calcium and magnesium ions to bind with salt ions and precipitate as solids. Simultaneously, water vapor rises and condenses on the cooler upper walls, producing purified softened water that exits the system. The diagonal barrier separates the sediment zone from the clean water layer above.

Used on plumbing, HVAC, or home appliance educational pages to explain ion-exchange water softening; targets homeowners researching water treatment solutions or DIY maintenance guides.
