PERFORMANCE DATA

IMPORTANT:
Read this performance data and compare the capabilities of
this system with your actual water treatment needs.
It is recommended that before installing a water treatment
system, you have your water supply tested to determine your
actual water treatment needs.
This system has been tested according to NSF/ANSI 58 for the
reduction of substances listed below. The concentration of the
indicated substances in water enteringthe sysem was reduced
to a concentration less than or equal to the permissible limit
for water leaving the system as specified in NSF/ANSI 58.
The GRO-350B/GRO-350M shall only be used for arsenic
reduction on chlorinated water supplies containing detectable
residual free chlorine at the system inlet. Water systems using
an in-line chlorinator should provide a one-minute chlorine
contact time before the RO system.
Do not use with water that is microbiologically
WARNING:
unsafe or of unknown quality without adequate disinfection
before or after the system. Systems certified for cyst reduction
may be used on disinfected waters that may contain filterable
cysts.
NOTE: Substances reduced are not necessarily in your water.
Filter must be maintained according to manufacturer's
instructions, including replacement of filter cartridges.
The tested efficiency rating for these systems is 22.05%.
Efficiency rating means the percentage of the influent water
to the system that is available to the user as reverse osmosis
treated water under operating conditions that approximate
typical daily usage.
The tested recovery rating is 38.65%. Recovery rating means
the percentage of the influent water to the membrane portion
of the system that is available to the user as reverse osmosis
treated water when the system is operated without a storage
tank or when the storage tank is bypassed.
The GRO-350B/GRO-350M has been tested for the treatment
of water containing pentavalent arsenic [also known as As(V),
As(+5), or arsenate] at concentrations of 0.050 mg/L or less.
This system reduces pentavalent arsenic, but may not remove
other forms of arsenic. This system is to be used on water
supplies containing a detectable free chlorine residual or on
water supplies that have been demonstrated to contain only
pentavalent arsenic. Treatment with chloramine (combined
chlorine) is not sufficient to ensure complete conversion
of trivalent arsenic to pentavalent arsenic. Please see the
Arsenic Facts section of the Performance Data Sheet for
further information.

Arsenic Fact Sheet

Arsenic (abbreviated As) is found naturally in some well
water. Arsenic in water has no color, taste or odor. It must
be measured by a lab test. Public water utilities must have
their water tested for arsenic. You can get the results from
your water utility. If you have your own well, you can have
the water tested. The local health department or state
environmental health agency can provide a list of certified
labs. There are two forms of arsenic: pentavalent arsenic [also
called As(V), As(+5), and arsenate] and trivalent arsenic [also
called As(III), As(+3) and arsenite]. In well water, arsenic may
be pentavalent, trivalent, or a combination of both. Special
sampling procedures are needed for a lab to determine what
type and how much of each type of arsenic is in the water.
Check with the labs in your area to see if they can provide
this type of service. Reverse osmosis (RO) water treatment
systems do not remove trivalent arsenic from water very well.
RO systems are very effective at removing pentavalent arsenic.
A free chlorine residual will rapidly convert trivalent arsenic to
pentavalent arsenic. Other water treatment chemicals such as
ozone and potassium permanganate will also change trivalent
arsenic to pentavalent arsenic. A combined chlorine residual
(also called chloramine) may not convert all the trivalent
arsenic. If you get your water from a public water utility,
contact the utility to find out if free chlorine or combined
chlorine is used in the water system. The GRO-350B/GRO-
350M system is designed to remove pentavalent arsenic.
It will not convert trivalent arsenic to pentavalent arsenic.
The system was tested in a lab. Under those conditions, the
system reduced 0.050 mg/L (ppm) pentavalent arsenic to
0.010 mg/L (ppm)(the USEPA standard for drinking water)
or less. The performance of the system may be different at
your installation. Have the treated water tested for arsenic to
check if the system is working properly. The RO component
of the GRO-350B/GRO-350M system must be replaced every
12-24 months to ensure the system will continue to remove
pentavalent arsenic. The component identification and
locations where you can purchase the component are listed in
the installation/operation manual.
