Q:

How does a Culligan water softener work?

A:

Quick Answer

Culligan uses a water softening technique to filter water in a home. It removes the harsh minerals found in hard water and makes the water gentler on everything that uses it. The filtration method involves separating the mineral particles from the water particles through the process of reverse osmosis.

Reverse osmosis works by forcing water molecules through a semi-permeable membrane using intense pressure. This membrane allows only water to pass through and keeps contaminants separate. Soft water contains few or no dissolved minerals; these minerals could be calcium, iron or magnesium.

Water softening uses a process called "ion exchange." This process is done with many tiny resin beads that contain sodium ions. The water passes through these beads, causing the resin beads to attract the dissolved minerals and release the sodium ions. Once the resin beads have released all of their sodium, the system will need to be refilled. Culligan offers a Salt Service program that delivers and replaces the salt.

Water hardens naturally as it moves through the water cycle. The Water Quality Association defines hard water as water that contains more that 1 GPG (grain per gallon) of dissolved minerals. Soft water does not contain these minerals and is easier on skin and dishes. Culligan claims that soft water also makes cleaning easier and allows for the reduced use of chemical cleaners.
