Stage 1: Fill/Dissolve
Water is directed down the media bed and through the distributor tube at a controlled rate, so the treated water entering the brine tank creates brine for the next regeneration.
Stage 2: Regenerate (Upflow)
The control valve directs water through the brine injector, drawing brine from the regenerant tank. The brine moves down the distributor tube, through the resin bed, and up to the drain. Water softening sodium ions displace hard water causing ions, sending them to the drain.
Stage 3: Backwash (Upflow)
The flow of water is directed down the distributor tube and up through the resin bed. During the backwash cycle, the resin bed expands, and debris is flushed to the drain.
Stage 4: Rinse (Downflow)
The control valve directs water through the resin bed, up the distributor tube, and to the drain. Any remaining brine residual is rinsed from the resin bed.
Stage 5: Service (Downflow)
Untreated water moves through the resin bed and up through the distributor tube. The hardness ions attach to the resin and are removed from the water. The water is refined as it passes through the resin bead.
