Advanced Water Filtration Media DMI-65 for removing Iron & Manganese
The DMI-65 is the most advanced 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 advanced 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.
