At last…an answer to your iron problems.
How does the Iron Master Work?
When water enters the IRON MASTER, it passes through a bubble of
compressed air that adds oxygen to it.
The water then passes through a filter bed. The filter material enhances a
reaction that separates the iron from the water. The insoluble flakes of iron
that result are then caught by the filter bed. (If you’d like to know the
chemistry see below!) The iron-free water then flows to your faucets.
The IRON MASTER replenishes itself every one to three days in a process
that washes the iron out from the filter and down the drain, while refilling
the compressed air bubble. This happens automatically during the night.
Why is it so economical?
The IRON MASTER costs almost nothing to run. This is because:
- The filter material does not change chemically during the process,
so it is not used up and will last indefinitely. - The other key element in the whole process is the oxygen and that is
freely available in the air. - Finally, the replenishment process is largely driven by the water
pressure in your system, so the IRON MASTER’s only running cost is
a handful of dollars a year in electricity.
So you’d really like to know the chemistry…
The filter media, which is Manganese Dioxide based, catalyses a reaction
that turns ferrous iron, usually found in water in the form of ferrous
bicarbonate [Fe(HCO3)2], which is soluble in water, into ferric oxide
(Fe2O3) and ferric hydroxide [Fe(OH)3] which are insoluble. This is the
same reaction that takes place when iron-bearing water is exposed to air
and which leads to staining of fixtures.
