1. The backwash phase removes dirt from the
mineral tank. 2. Recharging the mineral tank with sodium from the
brine solution displaces calcium and magnesium, which is then washed
down the drain. 3. The final phase rinses the mineral tank with
fresh water and loads the brine tank so it's ready for the next
cycle.
Water passing through the mineral tank loses
positively charged calcium and magnesium ions to negatively charged
plastic beads. The brine tank holds a salt solution that flushes the
mineral tank, replacing calcium and magnesium ions with sodium. A
meter at the top of the mineral tank regulates recharging cycles.
The valve assembly routes water flow for each phase of the
regeneration cycle.
