The Culligan Process
Your Culligan water conditioner consists of
three basic components, (A) the Control Valve,
(B) the Mineral Tank, and (C) the Brine System.
A. The exclusive Culligan control valve
automatically performs a variety of
tasks that are necessary for the proper
operation of your water conditioner. These
tasks, commonly referred to as cycles
or operating positions, are
Service,
Regeneration,
and
Brine Refill
.
1.
Service:
While the control valve is
in the “Service cycle”, hard water is
directed down through the column of
Cullex
®
resin where hardness minerals
are removed from the water. The
softened water is then directed into
your household plumbing lines. The
ability of the Cullex resin to remove
hardness minerals needs to be periodically replenished; this is referred to as . . .
2.
Regeneration:
While the control valve is in the “Regeneration cycle”, water is first
directed up through the column of Cullex resin to flush accumulated sediment out of the resin
and down the drain. Then, the regenerant brine solution is slowly drawn from the bottom of
the salt storage tank of the Brine System and is directed down through the column of Cullex
resin, restoring the ability of the resin to remove hardness minerals from your water supply.
Once completed, the regeneration cycle is followed by . . .
3.
Brine Refill:
While the control valve is in the “Brine Refill cycle”, a predetermined amount
of water is directed to the salt storage tank of the Brine System so that additional salt can
be dissolved to provide the brine solution that will be needed for the next regeneration
cycle.
B. The Mineral Tank contains the Cullex resin column, Cullsan
®
underbedding, and an outlet
manifold (the Culligan Municipal also includes carbon media for chlorine taste & odor
reduction). The number of gallons of hard water that can be softened by the Cullex resin column
before it needs regeneration is called the “capacity” of the resin column, and depends upon the
amount of hardness minerals in each gallon of water (expressed as grains per gallon) and upon
the amount of regenerant brine solution (expressed as pounds of salt) passed through the resin
column during regeneration.
Your Culligan service person, taking into account the hardness of your water and the amount
of softened water your household may reasonably expect to use each day, has carefully
established how often the softener will regenerate and how much salt will be used for each
regeneration. This will ensure that all of your soft water needs will be fulfilled without using an
excessive amount of salt.
C. The Brine System consists of a salt storage container and hydraulic Dubl-Safe
™
valve. The salt
storage container holds the salt that is used to make the regenerant brine solution. The hydraulic
Dubl-Safe valve limits the amount of water that is returned to the salt storage tank during the
brine refill cycle.
Since a predetermined amount of salt is dissolved with each brine refill cycle, the salt must be
periodically replenished in order to maintain efficient operation. Your Culligan service person
will be able to tell you about how often salt must be added to the salt storage container.
