Quantum DMI-65 – Advanced Iron and Manganese Removal
Media
Quantum DMI-65 is a revolutionary catalytic filtration media
engineered for the removal of iron, manganese, arsenic, and heavy metals
from groundwater and industrial process water. Developed in Australia by Quantum
Filtration Technologies, this advanced media delivers outstanding
performance, reliability, and longevity in both municipal and industrial water
treatment systems.
Unlike traditional
filtration media, DMI-65 does not require costly chemical regeneration.
Instead, it utilises a permanent catalytic surface that activates the
oxidation process, transforming dissolved contaminants into easily filterable
solids. This makes DMI-65 one of the most efficient and cost-effective
solutions for clean, safe, and high-quality water production.
Innovative
Catalytic Technology
At the core of DMI-65
lies its patented catalytic surface coating, designed to accelerate the
oxidation of dissolved iron and manganese. When water passes through the media,
dissolved iron (Fe²⁺) and manganese (Mn²⁺) are rapidly oxidised into insoluble
forms (Fe³⁺ and Mn⁴⁺) that can be easily filtered out.
This catalytic process
occurs in the presence of a small amount of oxidant—typically sodium
hypochlorite (NaOCl) or chlorine—ensuring complete and efficient removal of
metals. Unlike other media that require constant regeneration with potassium
permanganate or other harsh chemicals, DMI-65 maintains its activity indefinitely
when operated correctly.
Key
Advantages of DMI-65
- Chemical-Free Regeneration:
The media does not require continuous chemical regeneration. Once activated, it remains effective for up to 8–10 years under normal operating conditions. - Superior Removal Efficiency:
Capable of removing iron levels up to 15 mg/L and manganese up to 7 mg/L, producing crystal-clear water that meets or exceeds WHO drinking water standards. - Extended Media Life:
The catalytic coating is stable and permanent, giving DMI-65 a service life of 5 to 10 years depending on water quality and system design. - Cost-Effective Operation:
Reduced chemical usage, minimal maintenance, and long media life contribute to significantly lower operational and replacement costs. - Environmentally Safe:
DMI-65 is non-toxic, environmentally friendly, and safe for potable water applications. It produces no harmful by-products or sludge requiring special disposal.
Applications
Quantum DMI-65 is widely used in various water treatment systems,
including:
- Municipal drinking water treatment
- Groundwater and borehole filtration
- Industrial process water
- Mining and mineral processing
- Food and beverage industries
- Power generation and boiler feed systems
- Agricultural irrigation and livestock water
The versatility of DMI-65 makes it
suitable for both new installations and retrofitting existing sand or
multimedia filters, offering immediate improvement in water quality and
performance.
How
DMI-65 Works
- Pre-Oxidation:
A small dose of oxidant (such as chlorine or sodium hypochlorite) is added to the incoming water. This initiates the oxidation of dissolved iron and manganese. - Catalytic Reaction:
When water passes through DMI-65, the media’s catalytic surface accelerates the oxidation process, converting metals into solid particles almost instantly. - Filtration:
The insoluble metal oxides are trapped within the media bed and removed during normal backwashing cycles. - Continuous Performance:
Since the catalytic surface is not consumed in the reaction, the media continues to perform consistently without chemical regeneration.
Operating
Conditions
- pH Range:
5.8–8.6 (optimal 6.8–7.5)
- Temperature:
5°C–45°C
- Filtration Rate:
5–12 m³/m²/hr
- Backwash Rate:
25–30 m³/m²/hr
- Media Life:
5–10 years depending on water chemistry and operation
Maintaining proper
oxidation and pH levels ensures maximum performance and consistent results.
Performance Benefits
- Removes iron, manganese, arsenic, and heavy metals
effectively
- Delivers crystal-clear water with no metallic
taste or odour
- Prevents staining and clogging in pipelines, RO
membranes, and plumbing systems
- Reduces maintenance downtime and cleaning
frequency
- Ensures long-term operational stability and
efficiency
DMI-65’s unique ability to remove
multiple contaminants simultaneously gives it a distinct advantage over
traditional filtration media.
Environmentally
Responsible and Safe
Quantum DMI-65 is an eco-friendly filtration media certified
safe for drinking water applications. It does not leach contaminants or require
hazardous regeneration chemicals. Its long operational lifespan and minimal
chemical use make it an ideal solution for sustainable water treatment systems.
In industrial settings,
DMI-65 helps reduce environmental compliance costs by minimising waste and
ensuring effluent water meets strict discharge standards.
Installation
and Maintenance
DMI-65 can be used as a direct
replacement for sand or manganese greensand in existing filter systems.
Installation is simple and requires no special equipment. Routine backwashing
with clean water is sufficient to maintain performance and prevent clogging.
For best results,
pre-filtration may be required for high turbidity water, and periodic testing
of oxidant residuals ensures consistent catalytic activits.
