calcium and magnesium to be moderately

What are some of the ideal
applications for OneFlow
™ ?
Virtually any application where scale
reduction or scale removal from water
hardness is required or desirable. For
example: Hotels, Restaurants, Apartment
Buildings, Office Buildings, Condo
Complexes, Boilers, Irrigation Systems,
Humidifi ers, Distillers, Steam Generators,
Solar Heating Systems, Tankless Water
Heaters, RO Pre-Treatment, Misting
Systems, Tract Homes Builders,
Laundromats and numerous Food Service
applications are all ideal applications for a
OneFlow
™ system.
How about other chemicals
found in city water, such
as Fluoride and Chlorine,
does OneFlow
™ remove
them?
No. We all know the important role that
chlorine (or chloramine) plays in a public
water system. It assures the delivery of
safe potable water to every customer.
Fluoride is commonly added to munici-
pal water systems because of the prov-
en benefi ts it possesses in helping to
develop children’s teeth and to prevent
tooth decay. OneFlow
™ media, by itself,
does not remove either of these additives
from water. However, some OneFlow
™
cartridge systems contain carbon-based
media to remove and reduce chlorine
in Food Service and other Point-Of-Use
applications. Please contact your local
authorized OneFlow
™ Rep for the system
most appropriate for your specifi c appli-
cation.
What factors may effect
OneFlow’s system perfor-
mance?
Water chemistry and peak fl ow rate are
the guidelines used to assure optimal
system performance. Most municipally
treated (city) water falls well within our
performance guidelines to ensure scale
control results. However, there are chem-
istry limitations related to possible fou-
lants and interference ions. Water known
to contain visible dirt and debris must be
strained using a wye-pattern strainer or
equivalent (100 mesh) before OneFlow
™
tank systems. More details are available
on the product datasheets and IOMs.
As with any water treatment technology,
correct sizing of the system is important
to ensure proper performance. However,
OneFlow
™ is more forgiving of fl ow varia-
tions and unplanned peaks than a con-
ventional water softener.
Does the media in a
OneFlow
™ system need to
be replaced?
Yes. Tank-based systems require media
replacement every three years. Systems
should be installed with this in mind. An
isolation valve with a by-pass loop is rec-
ommended for most commercial applica-
tions so the tank(s) can be taken off-line
for media replacement. Filter housing
based systems require cartridge replace-
ment every year. Please refer to and
follow the instructions in the Installation,
Operation & Maintenance manual includ-
ed with the OneFlow
™ system.
Are there any application
limitations to OneFlow
™ ?
Untreated well water may pose a limita-
tion to OneFlow
™ due to the unknown
chemistry it often possesses. High hard-
ness is never a problem for OneFlow
™ ,
but with well water, hardness minerals
are often accompanied by other contami-
nants with levels outside of our operat-
ing guidelines. Additionally, closed-loop
systems that do not offer a “blow-down”
or “fl ush valve” are not recommended
because the micro-crystals need to exit
the system.
How easy is it to install a
OneFlow
™ system?
For anyone who has ever installed a Water
Pressure Reducing Valve or a Backfl ow
Preventer, installation of a OneFlow
™ sys-
tem will be relatively easy. Tank systems
offer “sweat” or “plastic MPT” connection
sizes in
3 / 4 ", 1" & 1 1 / 4 ". Larger tanks offer
single socket or manifold connections in
2" sizes. Several OneFlow
™ installation
accessories are offered to accommodate
most applications. OneFlow
™ systems
are compact allowing for easy installation
when space is limited. OneFlow's
™ light
weight makes it easy for the installer to
transport with nothing more than a hand
truck.
What are the ongoing
maintenance costs and
considerations for
OneFlow
™ ?
One of the great benefi ts of the OneFlow ™
technology is the dramatically reduced
maintenance requirements. Other than
the planned media replacement, there is
nothing else required. For tank systems,
the media replacement is once every
three years, and for fi lter housing sys-
tems, it's once a year. That's it.
Why is OneFlow ™ a
“Green Technology”?
OneFlow ™ is truly a “Green product”
because it saves water and energy in the
following ways:
1. Reduces Energy Consumption –
OneFlow
™ uses no electricity and
reduces energy consumption by
keeping heat transfer surfaces free of
energy-robbing scale formation.
2. Reduces Chemical or Raw
Material Consumption – OneFlow ™
requires no chemical or signifi cant
ongoing consumable (salt, as an
example)
3. Reduces Waste Water Discharge and
Water Consumption – Because
OneFlow ™ does not discharge or
require backwashing it meets
both objectives.
4. Reduces Space Requirements –
OneFlow
™ systems use approximately
75% less fl oor space than water
softeners.
5. Retains nature's minerals in the
water. The benefi cial minerals,
calcium & magnesium, are
completely retained.
