QUANTUM (DMI-65) refers to a proprietary advanced catalytic filtration media used primarily for the removal of iron, manganese, arsenic, and other contaminants from water. It’s widely used in municipal, industrial, and commercial water treatment systems, including applications involving pool water treatment, potable water supply, and wastewater management.

QUANTUM (DMI-65) is a revolutionary filtration media designed to remove dissolved metals such as:

  • Iron (Fe)

  • Manganese (Mn)

  • Arsenic (As)

  • Aluminum (Al)

  • Hydrogen sulfide (H₂S) (when used with chlorine pre-treatment)

It is not consumed in the filtration process, meaning it has a long operational life (up to 10 years under optimal conditions), making it cost-effective over time.
