A water softener typically has two connected systems; a media tank filled with resin that has a mechanical control valve, and a brine tank filled with salt. Everyone knows that water softeners are supposed to be filled with salt, but why exactly is that? The answer lies in how a water softener functions.

Ion Exchange

A water softener works through the simple process of ion exchange. This means that ions (postively or negatively charged atoms) trade places with other ions as water passes through; in the case of a water softener, it means that hardness ions (mostly calcium and magnesium) are exchanged for sodium ions. 



Water enters the inlet of the valve and then travels into the media tank, passing through the electrically charged resin beads. Since hardness ions are more strongly charged than sodium, they exchange places with it when they pass through the resin. Softener resin may also be used to attract other positive ions like iron, manganese, and barium. 


The now softened water passes through a bed of gravel that serves as a stable base for the resin bed and into the distributor, a long riser tube that connects to the control head. At the bottom of the riser tube is a basket with narrow slits, which is designed to keep resin from exiting the softener and clogging the homeowner's plumbing; the softened water passes through and exits the control valve, ready for use.


Eventually, the capacity of the resin to attract hardness minerals is exhausted, but even before that occurs the resin may become channeled; that is, it may form pockets where no resin is present and thus not all water passing through the system will be softened. Restoring the proper shape and capacity of the resin bed is accomplished by a process called regeneration. 

Regeneration


Backwashing 
The first step in regeneration is the backwash. This process reverses the flow of water in and opens the valve to the drain so that excess water is run through the media bed, scrubbing it of dirt and sediment before lifting and expanding it. Our systems utilize a second, shorter backwash after the brine draw to ensure the media is thoroughly scrubbed.

Brine Draw and Slow Rinse
After the backwash cycle is completed, the valve remains open to the drain and trickles out a small amount of water, creating a Venturi effect that draws brine solution into the softener from the brine tank. This brine mixes with water and is slowly rinsed throughout the media bed, knocking off hardness ions and sending them down the drain while replenishing the resin with fresh sodium ions. The system continues to be rinsed with water to ensure no brine solution remains.

Rapid Rinse
Water is sent down the media bed rapidly which flushes any remaining brine as well as residual hardness and other contaminants. This process also serves to pack the resin bed, preparing it for the next service cycle.

Brine Fill
Finally, new water must be added to the salt tank to dissolve more salt and create brine solution to replace what was used during this last regeneration. Once this cycle is complete, the control valve moves to the home position, and your system is ready to provide soft water again.

What exactly is hard water? Essentially it is water with a high concentration of minerals, especially calcium and magnesium. Although these minerals are not harmful for consumption, they can be a real annoyance in the home, as the calcium and magnesium tends to deposit on fixtures, shower doors, and tub walls, making cleaning day an even bigger hassle. Hardness is usually measured either in parts per million (typically abbreviated ppm) or more commonly in grains per gallon (gpg). Below, you can see water hardness represented throughout the United States:

Get Started Now
As you can see, much of the country does not have access to naturally occurring soft water. Unfortunately, this has hidden costs for the homeowner in the form of higher energy and cleaning bills, as hard water interferes with the ability of cleaning products in dishwashing and laundry settings and also coats the heating element in your water heater, requiring more energy to bring the water to the same temperature. 

What's the best way to combat this issue? With an ion exchange water softener. Special resin beads inside the softener act as magnets, attracting the calcium and magnesium ions in the water and replacing them with sodium ions for soft water that no longer stains or causes dry or itchy skin.
