ABSTRACT:
An improved process for regenerating the ion exchange resin in a water softening system. The process substantially reduces the amount of water and salt required for regeneration of the resin. The process includes the steps of venting the resin tank to the atmosphere and draining eventually all of the water from around the resin. Next, a brine solution is added to the resin tank. This is allowed to remain in contact with the resin until the resin is regenerated, preferably aided by energizing a vibrator positioned on the exterior of the tank. Next, the brine solution is drained from the resin tank which is then filled with water to rinse the brine from the resin. After rinsing, the resin is ready for use.
