is an organic form of iron that can combine with other naturally
occurring organic materials such as humic acids (tannins). It can give
the water a yellow to brownish hue and is often found in shallow
groundwater wells, surface water or groundwater under the influence of
particle size of colloidal iron is very small — in the micron and
submicron size ranges — compared with other forms, and it has a surface
area and charge that will prevent it from being removed in the same way
that Iron (Fe) is. Consequently, colloidal iron is extremely difficult
to remove and is basically non-filterable with typical media type
treatment such as our Iron Max.
and will require strong oxidation, usually by injection of chlorine,
ozone or hydrogen peroxide followed by filtration (The Iron Max) to
remove the oxidized iron. Activated carbon filtration may be also needed
to remove any residual chlorine.
Note: Colloidal iron will require
longer contact time and a separate retention tank will be required.
