Twin Alternating Water Softeners with Fleck Control Valves
Twin softeners are ideal for situations where uninterrupted flow of soft water is a must. 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 will begin regeneration and wait in standby until the other tank is ready for regeneration.
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.

Ordering Notes:
* Softeners are available with several options of valve voltages. Please add the appropriate voltage code to the end of the model when ordering.
110v/60Hz = 116 Example: W-S744ST-116
220v/60Hz = 216 Example: W-S744ST-216
220v/50Hz = 215 Example: W-S744ST-215
**5 gpm per sq. ft. of media is the best design condition for filtration. For relatively clean water, you may go up to design criteria of 15 gpm per sq. ft. Backwash flow rate based on 25 psi pressure drop.
Skid mounting, control panel and custom sizes and configurations are available upon request.
