How Water Softeners Work

To understand the pros and cons of different water softener systems, it helps to first learn how water softening works. The process relies on a method called ion exchange to remove minerals like calcium and magnesium from the water.

Inside a water softener is a resin bed made up of small plastic beads or zeolite crystals. These beads carry a sodium ion charge. As hard water passes through the resin bed, the calcium and magnesium ions swap places with the sodium ions. This effectively softens the water by replacing the hard water mineral ions with sodium.

After this ion exchange process takes place for a while, the resin beads become saturated with calcium and magnesium, diminishing their ability to soften water. At this point, the softener system goes through a regeneration cycle.

Regeneration washes the resin bed with a salt brine solution, which resets the ion exchange capacity. The brine forces out the built-up hard water minerals which are flushed away down the drain. Once regeneration is complete, the resin beads contain sodium ions again and can continue softening your household water.

It’s important to note the difference between water softening and water conditioning. Conditioning doesn’t remove hard water minerals but instead uses chemicals like polyphosphates to alter how the minerals behave. Softening with ion exchange is more effective and provides all the benefits of soft water.

Some key reasons to soften your water include:

  • Improved lathering of soaps and detergents
  • Minimized mineral scale buildup on plumbing and fixtures
  • Reduced spotting on dishes, glassware, and utensils
  • Better protection for water-using appliances
  • Softer feeling hair and skin after bathing and showering

Now that we’ve reviewed the ion exchange process that allows water softeners to work their magic, let’s look at how Aquasure and Fleck systems compare.
