SYSTEM COMPONENTS: PRE-TREATMENT; Water Softener
DESCRIPTION:
Water softening consists of a single water softener to meet
system flow demands, reduction ratios, and user criteria. The water softener
in this system is commercial/industrial grade, automatic, and custom sized
to meet the demand.
The water softener in the system has a 7 day calendar time clock to
control regeneration. The controller can be set to regenerate at pre-set times
on specific days, giving the user maximum flexibility. The controller has an
interlock feature to prevent the RO from running during the regeneration cycle.
When regenerating a red light is illuminated as an indicator of this cycle and
the RO will not run due to the interlock.
The resin is a premium grade, strong acid cation for high flow rate condensate
demineralizing made from food-grade materials that meet FDA CFR 173.25
specifications. The water softener is regenerated with salt brine that is made
from quality, premium grade salt pellets specified for water softening and/or
conditioning.
Do not use rock salt
, as this form of salt carries impurities and
will tend to have adverse effects on your water pre-treatment system. For information
on about brine tanks, see the previous section titled “System Components: Brine Tanks”.
MONITORING REQUIREMENTS:
Daily:
This device requires daily monitoring to insure the controller clock is properly set
Daily:
Check pre and post-
filter pressure, and ΔP (
pressure drop
) across it while the RO is
running
Daily:
Check the salt level in the brine tank is greater than 50%
Daily:
The hardness, measured post softener, should be tested daily while the softener is under
peak demand, usually late in the afternoon.
MAINTENANCE:
-
The salt level in the brine tank should be filled periodically so it doesn’t fall below 50%.
-
Better Water LLC recommends that tank media be changed every three years unless…
… otherwise specified by the medical director and/or company polices,
… or the hardness breakthrough is greater than 2 grains per gallon after two verified regeneration
cycles.
