HOW THE CGFE SYSTEM WORKS
Your Rainfresh CGFE filter utilizes oxidation and filtration technology to remove dissolved
Iron, Manganese and Hydrogen Sulphide from water. Rainfresh Greensand Filter is based on
the technology of oxidation and filtration. It incorporates a special high-oxidant media called
Manganese Greensand. When water flows through the Greensand filter system, dissolved
Iron and Manganese are oxidized to insoluble precipitates by contact with the greensand
media, and simultaneously filtered out. Hydrogen Sulphide is reduced to an insoluble sulphur
precipitate, which is also filtered in the bed.
Water coming out of the greensand filter is virtually free of Iron, Manganese and Hydrogen
Sulphide.
When the oxidizing capacity of the greensand bed is exhausted, the system automatically
undergoes a process called
REGENERATION
, during which it backwashes to rid itself of the
trapped Iron, Manganese & Hydrogen Sulphide and recharge it’s removal capability using a
chemical powder called POT PERM (Potassium Permanganate) which is stored in a separate
small container.

SAFETY PRECAUTIONS
-
Follow all applicable province/state and local regulations.
-
Handle the filter carefully. Do not lie on side, turn upside down, drop or drag.
-
This Greensand Filter uses POT-PERM (Potassium Permanganate) to regenerate. Please handle POT-PERM carefully
and store in a secure cool place where it cannot be misused or mishandled.
-
Install a pressure regulator and water hammer arrestor if pressure exceeds maximum rating at any time.
Note:
If
daytime pressure is over 80 psi, night time pressure may exceed maximum pressure rating.
Cautions Before Installation
-
To operate properly, the well pump flow rate must exceed the backwash flow rate (5 US GPM (19 LPM)).
-
Warning:
If your well pump does not deliver this flow rate, do not install the unit as it will not work properly
.
-
This system does not kill or remove bacteria or any other pathogenic microorganisms. To continuously disinfect all
the water in your house, we recommend that you install a Rainfresh UV system. Call Rainfresh for details.
-
For use on cold water only.
