DMI 65 is a revolutionary silica sand based filtration media designed for the removal of iron and manganese without the use of potassium permanganate. The unique microporous structure of DMI-65 efficiently removes dissolved iron to as low as 0.005 ppm and manganese to 0.001 ppm. After initial activation, the DMI-65 acts as an oxidation catalyst with immediate oxidation and filtration of the insoluble precipitates. The media has been used extensively in a wide variety of applications in Japan for over 20 years. Quantum Filtration manufactures DMI-65 under license in Western Australia.
DMI-65 has been tested and certified by the Water Quality Association in accordance with NSF/ANSI 61.
