“Testing was performed under standard laboratory conditions, actual performance may vary”
“This system is acceptable for treatment of influent concentrations of no more than 27 mg/L nitrate and 3
mg/L nitrite ( In combination measured as N), and is contingent on the proper functioning of the booster
pump included as part of this system to deliver a minimum pressure of the membrane of at least 40 psi”
“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 0.30 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 detectable free chlorine residual or on water supplies that have been demonstrated to
contain only pentavalent arsenic. Treatment with chloramines (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 (As) is a naturally occurring contaminant found in many ground waters. It generally occurs in two
forms (valences or oxidation states): pentavalent arsenic (also known as As(V), As(+5), or arsenate) and
trivalent arsenic (also known as As(III), As(+3), or arsenite). In natural ground water, arsenic may exist as
trivalent arsenic, pentavalent arsenic, or a combination of both. Although both forms of arsenic are
potentially harmful to human health, trivalent arsenic is considered more harmful than pentavalent
arsenic. More information about arsenic and its toxicity can be found on the U.S. Environmental
Protection Agency website at http://www.epa.gov/safewater/arsenic.html.
This system is designed to remove only pentavalent arsenic. This treatment system does not provide a
feature for conversion of trivalent arsenic to pentavalent arsenic. The system may remove some trivalent
arsenic, however, it has not been evaluated for its ability to remove trivalent arsenic.
Trivalent arsenic is generally more difficult to remove from drinking water than pentavalent arsenic.
Trivalent arsenic can be converted to pentavalent arsenic in the presence of an effective oxidant such as
free chlorine. The arsenic in water containing detectable free chlorine or that has been treated with
another effective oxidant will be in the pentavalent arsenic form.4 Treatment with chloramine (combined
chlorine) is not sufficient to ensure complete conversion of trivalent arsenic to pentavalent arsenic.
Consumers using public water supplies can contact their utility to verify whether free chlorine treatment
chemicals are being used. Private water supplies and waters that do not have detectable free chlorine
residuals should be analyzed to determine the form(s) of arsenic present and the potential need for
oxidation of trivalent arsenic to pentavalent arsenic.
Arsenic does not generally impart color, taste, or smell to water, therefore, it can only be detected by a
chemical analytical test. Public water supplies are required to monitor treated water for total arsenic
(trivalent arsenic plus pentavalent arsenic) and the results are available to the public from the utility.
Consumers using private water sources will need to make arrangements for testing. A total arsenic test
usually costs about $15-$30 and it is recommended the test be conducted by a certified laboratory. Local
health departments or environmental protection agencies can help provide consumers with a list of
certified laboratories. Some laboratories may also be able to analyze specifically for (speciate) the form(s)
of arsenic present in a water sample if requested.
This system is designed to remove only pentavalent arsenic. This treatment system does not provide a
feature for conversion of trivalent arsenic to pentavalent arsenic. The system may remove some trivalent
arsenic, however, it has not been evaluated for its ability to remove trivalent arsenic.
This treatment system was tested under laboratory conditions as defined in NSF/ANSI 53 Drinking Water
Treatment Units – Health Effects and was found to reduce 0.30 mg/L of pentavalent arsenic in the test
water to less than 0.010 mg/L under standard testing conditions. Actual performance of the system may
vary depending on specific water quality conditions at the consumer's installation. Following installation
of this system, the consumer should have the treated water tested for total arsenic to verify arsenic
reduction is being achieved and the system is functioning properly.
The arsenic removal component of this system must be replaced at the end of its useful life of 1-2 years.
The replacement component,
can be purchased directly from the manufacturer Kent RO Systems. Ltd.
