PERFORMANCE DATA

Important Notice: 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 the substances listed below. The concentration for the
indicated substances in water entering the system was reduced
to a concentration less than or equal to the permissible limit for
water leaving the system, as specified in NSF/ANSI 58.
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 this system is 6.60%. 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 15.82%. 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

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 RO-2550 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 RO-2550 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.
This system 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 reduce
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.
