1 Rating at 50 psi, 77°F, 750 mg/L TDS influent, without storage tank. 2 May vary with pressure.
* The daily production rate is the volume of product water produced by the system per day and is determined by testing in accordance with the procedure outlined in NSF/ANSI Standard 58.
** System’s Efficiency rating as verified by testing in accordance with NSF/ANSI standard 58. 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.
*** System’s Recovery rating as verified by testing in accordance with NSF/ANSI Standard 58. System’s 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.
**** Minimum TDS reduction per NSF/ANSI 58 is 187 mg/L. Influent TDS is 750 mg/L.
QCRO4V-50 system certified by WQA to NSF/ANSI 58 and
CSA B483.1 for the reduction of the following substances,
as verified and substantiated by test data: Arsenic V,
Barium, Cadmium, Chromium III and VI, Copper, Fluoride,
Lead, Radium 226/228, Selenium, TDS and Turbidity.
