Water Treatment Device Certificate Number 04 - 1647 Date Issued: July 27, 2009
Trademark/Model Designation GE RO Filtration System GXRM10RBL
Replacement Elements FX12M (RO Membrane) FX12P (Pre and Post Filters)
Manufacturer: General Electric Company The water treatment device(s) listed on this certificate have met the testing requirements pursuant to Section 116830 of the Health and Safety Code for the following health related contaminants: Microbiological Contaminants and Turbidity Cysts Turbidity
Organic Contaminants None
Rated Service Capacity: N/A
Inorganic/Radiological Contaminants Arsenic (pentavalent)1 Barium Cadmium Chromium (hexalent) Chromium (trivalent) Copper Fluoride Lead Nitrate/Nitrite2 Radium 226/228 Selenium
Rated Service Flow: 10 gpd
Conditions of Certification: Do not use where water is microbiologically unsafe or with water of unknown quality, except that systems certified for cyst reduction may be used on disinfected waters that may contain filterable cysts. 1 Claims for arsenic reduction shall only be made on water supplies maintaining detectable residual free chlorine at the reverse osmosis (RO) system inlet. Water systems using an in-line chlorinator should provide a minimum of 1 minute chlorine contact time before the RO system. 2 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 certified for nitrate/nitrite reduction only for water supplies with a pressure of 280 kPa (40 psig) or greater. A sampling and analysis test kit for nitrate is provided for checking the performance of this system. Frequent analysis is encouraged.
