The DMI-65 is the most sophisticated catalytic
water filtration media that has extremely high capabilities of
removing both Iron (Fe) and Manganese (Mn) simultaneously through
low cost catalytic oxidation and retention of precipitate. The
DMI-65 will also remove arsenic from a water supply given the
correct conditions.
The DMI-65 is one of the fewer catalytic water
filtration media’s in the world developed to remove iron and
manganese that is certified to NSF/ANSI 61 for drinking water
applications.
Quantum Filtration Medium Pty Ltd (QFM) and the
DMI-65 are fully supported in technical information.
Iron and Manganese
Iron can be removed by many different methods to
achieve the “World Drinking Standards”. These methods are regarded
as old technology in world standards, expensive in Chemical and
labour costs, Energy and ongoing costs and Maintenance costs.
Manganese however is much more difficult to
remove and expensive using traditional methods.
The DMI-65 is the most sophisticated catalytic reaction media in
the world and has a very high ability in removing iron and
manganese. The DMI-65 is also capable of removing other elements
from a water supply given the correct conditions.
The DMI-65 is the lowest cost method of removing
Iron – Manganese from a water supply. All other processes are
expensive to operate an difficult to maintain.
The DMI-65 has a life span of at least 5 to 8
years before needing to be replaced if the plant is maintained
correctly.
Catalytic Filter Media
In regard to how DMI 65 works, this is a
catalytic filter media boosting oxidation capacity of low cost
oxidant such as NaOCl. (Before the filter you inject oxidant.)
Iron and manganese in solution are in the form
of lower valence oxi-hydroxides (example, ferrous hydroxide).
Higher valence oxi-hydroxides (ferric hydroxide, red color) are not
soluble in water around neutral pH. When the water with iron and
manganese in solution and oxidant reaches the filter bed, the low
valence hydroxides oxidize to high valence; insoluble form and
precipitated particles are retained in the filter bed. This process
would take place normally in a matter of days to weeks. The
catalytic filter media makes this happen in minutes accelerating
the reaction a few hundred times.
The DMI-65 is a similar filtration media to
other iron and manganese removal medias, however the DMI-65 does
not need to be re-generated with potassium permanganate at all.
