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 substances listed below. The concentration of the indicated substances
in water eneterin gthe 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 RO-3500 is acceptable for treatment of influent concentrations of no more
than 27 mg/L nitrite in combination measured as N and is certified for nitrate /
nitrite reduction only for water supplies with a pressure of 40 psig (280 kPa) or
greater.
The RO-3500 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.
WARNING: Do not use with water that is microbiologically 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 11%. 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 24%. 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 RO-3500 has been tested for the treatment of water containing pentavalent
arsenic [also known as As(V), As(+5), or arsenate] at concentrations of 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 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.
