DMI-65 is a revolutionary Infusion Technology catalytic filtration media designed for the removal of iron and manganese without the use of potassium permanganate. The unique micro-porous structure of DMI-65 efficiently removes dissolved iron to as low as 0.001 ppm and manganese to 0.001 ppm. 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 for over 30 years.
Advantages of DMI-65
Eliminates Potassium Permanganate. Operates with continuous injection of sodium hypochlorite at low residual levels (0.1 to 0.3 ppm).
Wide pH range. Stable and satisfactory performance at pH 5.8 to 8.6.
High Flow Rates. DMI-65 can operate at linear filtration velocities up to twice that of conventional media with a Higher Operating Temperatures. Maximum operating temperature of 113° F (45° C).
Long Life. DMI-65 is not consumed in the process
providing considerable advantages over other processes or media.
Regeneration Not Required. After initial activation
only sodium hypochlorite feed is required.
System Compatibility. Physical properties are similar to that of competitive media
allowing conversion to DMI-65 without major hardware modifications.
Arsenic Removal. DMI-65 has been shown to be effective in the removal of arsenic associated with iron-containing influent. If necessary
ferric chloride can be introduced to treat waters with low influent iron levels or to enhance removal when treating waters with high levels of arsenic.
DMI-65 is made with Infusion Technology and not just a surface coating technology. unlike other catalytic water filtration media, giving DMI-65 the advantage of a long life span between 5 to 10 years and powerful performance.
Quantum Filtration Medium Pty Ltd manufactures DMI-65 in Western Australia.
DMI-65 has been tested and certified by the Water Quality Association in accordance with NSF/ANSI 61 and for use in England and Wales under Regulation 31(4)(a) of the water supply (Water Quality) regulations 2010 Sl No.994 (W.99).
