Conventional System Design: HE & LC Models
The Control Valve:
routes the water flow through the system and
controls the operating cycles. Hard water passes through the resin
bed to become soft. During regeneration, water flow is reversed to
backwash which cleans the resin bed. Brine is pulled in and then
rinsed out to regenerate the resin, preparing it to soften more water.
The brine tank is then refilled with fresh water for future cycles.
Regeneration cycles are based on digital logic, calculating daily
water use and then scheduling a cycle at the preset time. Cycles
can also be predetermined and programmed in the control if so
desired.
Brine tanks are
available in a variety
of sizes to fit in almost
any space and are blow
molded for strength
and durability.
Safety shut off
provides total brine
system shut down
to protect against
brine overflow.
Salt shelf permits
use of almost any
type of salt and
eliminates bridging
and mush by keeping
the salt dry.
The Brine System:
stores salt and water to make brine which is
used for regenerating the resin. Resin can be regenerated with
sodium from sodium chloride (softener salt) or potassium from
potassium chloride.
The Resin Tank:
contains
media called resin. The
resin attracts and collects
minerals from hard
water. Once the resin is
saturated with hardness
minerals it must be
cleaned and regenerated.
Once regenerated, the
resin is ready to soften
more water.
Resin tanks can be
exposed or covered
with a jacket or
insulated cabinet.
Historically, resin tank
construction was metal.
To eliminate destructive
corrosion, modern
tanks are made with a
molded liner that is
wrapped in fiberglass
for exceptional strength
and durability.
Resin is made
of cross-linked
polystyrene to
provide a long
life of softening
capacity.
The riser distributor
collects the water that
has been softened in the service cycle and
routes it to the outlet of the control valve. It
also aids in lifting and “fluffing” the resin bed
for the brining cycle.
The performance of a water softener is dependent on two key functions; a resin bed that cleans the water and precision
equipment that cleans the resin. The two most significant elements that differentiate one softener from another is the
volume of resin and the type of control valve.
