How does a softener
work? To wash off hard water minerals from the resin,
brine water is injected into the softener.Hard water fills the
tank. As it passes through the resin, the hard water ions are
attracted to the resin. By the time the water gets to the bottom
of the tank, it is soft.

Softening is a 4-Step Process
1.
The water softener
tank is filled with small diameter resin beads which are covered
with sodium ions. When hard water flows through the resin bed,
the beads act like a magnet, attracting the calcium and magnesium
ions in the water in exchange for the sodium ions.
2.
Eventually the resin
beads become saturated with the hardness mineral ions and must
be ‘re-charged”. This regeneration process is conducted
by the control valve on the top of the tank. The control valve
is the brain of the system.
3.
During regeneration,
a strong brine solution from the brine tank is flushed through
the resin tank, bathing the resin beads
in a stream of sodium ions from the salt in the brine. This
replaces the calcium and magnesium ions captured by the resin
beads
4.
The brine solution
carrying the displaced hardness minerals is flushed to the drain
with fresh water. The resin beads can be used over again.
Calculating Capacity
The resin capacity
is one of the first things to establish for softener size. An
average family uses 100 gal./day of water per person. A household
of four needs 400 gal/day of softened water. If the water has
a hardness of 20 grains per gallon, 8000 grains have to be removed
per day (400 gal. X 20 grains/gal.) With regeneration every
3-days, the minimum softener capacity should be 24,000 grains
(8000 grains/day x 3 days). A 1.0 cu. Ft. softener model should
be selected.
