1. The Genesis 2 AIO system should not be used on water having an iron content above
7 ppm or 7 mg/1.
2. Free chlorine should be removed before passing water through the media.
3. The Genesis 2 AIO removes dissolved iron from water, which is present as ferrous iron.
Iron can also exist in other forms such as bacterial iron, soluble organic iron and colloidal
iron. Those forms of iron cannot be removed effectively by an Genesis 2 AIO.
4. Any sequestering agents including polyphosphates and meta-phosphate should be
added after the Genesis 2 AIO System.
5. For high iron content in feed water (> 7 ppm) it is recommended to backwash the unit
with treaded water, so as to avoid contamination of bottom portion of the bed.
6. The unit must be backwashed a specified flow rate resulting in 60% bed expansion for
effective removal of precipitated iron and suspended solids.
7. The start-up backwash and rinse prior to new service installation is critical for cleaning
media of manufacturing color, taste and any trace amine odors. We recommend 2 bed
volumes of backwash followed by 2 bed volumes of fast rinse. This timing is explained in
Schedule B.
8. The backwash frequency shall be every 12 to 24 hours for continuous operating systems.
If the unit is operating intermittently, backwash per Fe Clear recommendations in
Schedule A.
