Softener Operation
As water enters the softener, it passes over a resin bed in a special tank. The resin consists of tiny beads of a
plastic called styrene. These beads attract and hold sodium ions and exchange the sodium for hardness ions
when encountered. Over time, the resin becomes saturated with hardness ions and no longer removes
hardness materials. The softener goes into a "regeneration" to flush hardness materials to the drain and refresh
the resin with sodium. Regeneration is typically programmed to take place in the middle of the night when little
or no water is in use.
Regeneration consists of four cycles:
1. Brine Draw / Slow Rinse Position
Brine Draw
is the process in which brine is drawn out of the brine cabinet and passed through the resin in a
downward direction. This rinses the resin and large amounts of sodium ions replace the hardness ions
accumulated during service.
Slow Rinse.
After brine is completely removed from the brine cabinet into the
resin tank the brine valve closes. Water replaces any remaining brine from the resin, flushing hardness ions
removed from the resin to drain.
2. Backwash Position
Backwash
is a rapid upward flow of water that loosens the resin bed and flushes iron particles, dirt and
sediments filtered in the bed out to the drain.
3. Fast Rinse Position
Fast Rinse
is a fast flow of water down through the resin tank that follows a
Backwash
. This flushes all
remaining brine from the tank and packs the resin bed for softening efficiency.
4. Brine Fill
Brine is water saturated with large amounts of a salt (sodium chloride). During
brine fill
, water flows into the salt
storage area after each regeneration and dissolves salt. During the regeneration process, hardness ions on the
resin beads are replaced or exchanged for sodium ions from the brine solution.
5. Service
When the softener is in the
Service Position,
water
flows through the system removing hardness minerals from
your water.
