System Performance

Daily production rate
Efficiency Rating(1)
Recovery Rating (2)
(1)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.
(2)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.
(3)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 water that may contain filter-
able cysts. The feed water must also be free of potential membrane foulants such as Iron, Hydrogen Sulfide and
maganese.
System Tested and Certified by NSF International against NSF/ANSI Standard 58 for the
reduction of the contaminants listed below. The concentration of the indicated substances in
water entering the system was reduced to a concentration less than or equal to the permis-
sible limit for water leaving the system, as specified in NSF/ANSI 58.
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 0.30 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 at the system inlet 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.
Testing was performed under standard laboratory conditions, actual performance may vary.
