Culligan Iron-Cleer - Manual (Page 8)

The concentration limits listed below reflect the maximum individual limit that each contaminant was
tested for separately without any interference of other contaminants in the influent water.
In reality, however, we know that these contaminants may be present in combination which may limit
the filter’s ability to remove these contaminants in higher concentrations. In some cases, individual
sellers of this equipment have had success removing higher concentrations of contaminants - iron,
for example - above the limitations we have listed. If you are considering the installation of this
system for the reduction/removal of iron, manganese and/or hydrogen sulfide beyond the printed
operating conditions below, we recommend that you consult the manufacturer for proper application.
Installation of this system under these circumstances may void part(s) and/or all of the system
warranty.
pH — The pH level of the influent water must be 7.0 - 8.5. A pH level of 7.0 - 8.5 is optimal for iron
reduction.
Iron — This system is rated for a maximum of 10 ppm of ferrous (clear water) and/or ferric (red
water) iron. Consult the factory if iron bacteria is present.
Hydrogen Sulfide — Often referred to as rotten egg odor, hydrogen sulfide will be reduced
significantly on water supplies containing less than 5 ppm. Consult the manufacturer if hydrogen
sulfide concentrations is greater than 5 ppm.
Organic Matter (Tannins) — The presence of organic matter such as tannins will prevent the
oxidation process of converting the dissolved element, such as iron or manganese, to a non-soluble
precipitate or solid substance, allowing it to be filtered out. The Iron Cleer™ is not designed to
remove organic bound iron.
