Single Water Softeners with Timered Valves Single Water Softeners with a timered valve are programmed to regenerate at a specific time of day.  They are usually scheduled to regenerate at 2am, when the demands for soft water are expected to be very low.  These can be set to regenerate every day, every two to three days, or on certain days of the week.
 
Single Water Softeners with Metered Valves Metered Water Softeners are prompted to regenerate based on the amount of water that has passed through the unit.  Like the timered softeners, these can be programmed to regenerate at a certain time of day.  Instead of regenerating on a specific day as a timered softener does, the metered softener does not schedule a regeneration until the specified amount of water have passed through the softener.  These units can save water by preventing unnecessary regenerations since it does not regenerate until the resin is near its capacity.
 
Twin Water Softeners with Metered Valves Ideal for situations where uninterrupted flow of soft water is a must, our twin softeners consist of two resin tanks.  One resin tank is always in service, while the other tank is in standby.  When the meter determines that the resin is near its capacity, it will switch the tank in standby to be in service, and the tank containing the exhausted resin switches into regeneration, and then into standby.
 

About Water Softening:

Hard Water contains dissolved minerals in the form of Calcium (Ca), Magnesium (Mg), and Iron (Fe).  Removal of these minerals is accomplished by softening the water through an ion exchange process using a water softener.  As the water flows through the mineral tank of the water softener, the dissolved minerals become attached to the resin, creating soft water.  Over a period of time the resin in the water softener will become exhausted, and the water softener will regenerate using a brine solution produced from the salt in the brine tank.


Advantages to Using a Water Softener:

  • Higher Quality Drinking Water
  • Prevents Hard Water Scale
  • Prevents Staining on Bathroom & Kitchen Fixtures as well as Dishes, Dishwasher, Washing Machine and Clothes
  • Significantly Reduces Soap and Cleaning Product Consumption
  • Provides Excellent Grooming & Cosmetic Benefits
  • Reduces Water Heating Costs
  • Prolongs the Life of Water Heaters, Icemakers, Dishwashers, Coffeemakers and Plumbing Fixtures.

How does a Water Softener work?

A typical water softener has four major items:

  1. Resin Tank
  2. Resin
  3. Automatic Valve or Controller
  4. Brine or Salt Tank

Hard water flows over resin in the resin tank. Resin is in the form of tiny beads that have a special chemical property. At low concentration of sodium in typical hard water, the resin beads adsorb (combine with them) the hardness of water and replace it with an equivalent amount of sodium in water. As hardness is removed the water becomes "soft". The resin has a fixed capacity of the amount of hardness it can remove. Once that happens the resin can no longer remove the water hardness and the resin is called "saturated" or exhausted..

Fortunately, the same resin when exposed to high sodium chloride (common salt) concentration reverses the process and adsorbs the sodium and releases the hardness. This property is utilized in regenerating the exhausted resin. This is done by temporarily stopping the softening process and exposing the resin to high salt solution from the brine tank. The entire process is controlled by the controller valve which works either on time of regeneration (normally set at 2 AM) or by a meter valve inside the controller preset to a calculated amount of water that can be softened before regeneration. After regeneration the controller rinses the resin to remove all salt not adsorbed by the resin. The entire cycle lasts less than 1 hour.

The softening process adds a very small amount of sodium in the water which comes from the exchange process. It is not directly added from the brine tank. For example, water with 10 grain hardness will have a sodium addition of 80 ppm in the water after softening.
 


Sizing and Selection Information for Water Softener:
Step 1: Calculate Total Hardness as GPG
Usually chemical analyses report calcium (Ca) and magnesium (Mg) in terms of parts per million (ppm) as calcium carbonate (CaCO3). However, in some cases, the analysis is reported in terms of the elements themselves. If this is the case, proceed as follows:

Calcium (as Ca)_________ × 2.50 = _________ppm Ca as CaCO3. (A)
Magnesium (as Mg) _________× 4.10 = _________ppm Mg as CaCO3. (B)
A _________ + B_________ = _____________Total Hardness PPM as CaCO3

Total Hardness PPM as CaCO3 _________ ÷ 17.1 = _________ GPG as CaCO3.

Step 2: Calculate Cubic Feet of Resin Required

_________ Gallons per Day × _________Total Hardness (GPG) = _________ Grains per Day

_________ Grains per Day ÷ 30,000 = _________ Cubic Feet of Resin Required

Select the appropriate softener based on the volume of resin. When between sizes, it is recommended to select the next size up.

Note: Above calculations are based on daily regeneration and maximum resin capacity. Regeneration based on 15 lbs. of salt per cubic foot of resin.
