Daily Production Rate Model WHAROS5: 18.46 gal./day (69.87 liters/day)
Efficiency Rating Model WHAROS5: 12.22%
Recovery Rating Model WHAROS5: 22.95%
1
Milligrams per liter, which is equivalent to parts per million (PPM).
2
Tested by NSF International according to NSF/ANSI Standard 58.
3
NSF minimum percent reduction requirement. Acceptance level for this substance is based on percent reduction,
rather than maximum effluent concentration.
4
Particles per milliliter.
5
Pico Curies per liter.
6
Nephelometric Turbidity Units.
7
Tested by Spectrum Labs, a qualified independent laboratory, against accepted industry protocol.
8
There is no maximum permissible effluent concentration for this substance because it is not included in the chemi-
cal reduction claims listed in NSF Standard 58. The maximum effluent concentrations listed were established by
Spectrum Labs and are based on one third of the target influent.
9
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 daily usage.
10
Recovery rating means the percentage of the influent water to the membrane portion of the system that is avail-
able to the user as reverse osmosis treated water when the system is operated without a storage tank or when
the storage tank is by-passed.
