Water Treatment Solutions Using DMI-65® for Deep Well Rehabilitation & Groundwater Treatment Projects

Groundwater is a critical resource for municipalities, industries, agriculture, and remote communities. However, deep wells and aquifers often suffer from iron, manganese, hydrogen sulfide, and other dissolved contaminants that ruin water quality and system performance. Water treatment using DMI-65® has emerged as a proven, high-performance solution for deep well rehabilitation and groundwater treatment projects, delivering long-term reliability with minimal chemical input.

Let's explore how DMI-65® works, why it is ideal for deep well applications, and how it supports sustainable groundwater treatment strategies.

Understanding the Challenges of Deep Well & Groundwater Treatment

Deep wells face unique challenges compared to surface water systems:

• Elevated dissolved iron & manganese

• Hydrogen sulfide (H₂S) odor & corrosion

• Biofouling & iron bacteria buildup

• Declining well efficiency & reduced yield

• High maintenance costs from frequent chemical treatments

Traditional rehabilitation methods, such as aggressive chemical dosing or mechanical cleaning, often provide only temporary relief and can damage well infrastructure or surrounding aquifers.

This is where catalytic filtration media like DMI-65® offer a superior, long-term alternative.

What Is DMI-65® Water Treatment Media?

DMI-65® is an advanced catalytic filtration media formulated to remove iron, manganese, arsenic, and hydrogen sulfide from groundwater sources. Unlike conventional filter media, DMI-65® works through a catalytic oxidation process rather than simple mechanical filtration.

Key Properties of DMI-65:

• High catalytic activity

• Operates effectively at low oxidant doses

• Long service life

• Resistant to fouling and degradation

• NSF/ANSI 61 certified for drinking water applications

These properties make DMI-65® particularly well-suited for deep well rehabilitation and continuous groundwater treatment systems.

How DMI-65® Works in Groundwater Treatment Systems

DMI-65® acts as a catalyst, accelerating the oxidation of dissolved contaminants so they can be filtered out efficiently.

Treatment Process:

1. A small dose of oxidant (chlorine, hypochlorite, or aeration)

2. DMI-65® catalyzes the rapid oxidation of iron & manganese

3. Oxidized contaminants are captured by the filter bed

4. Periodic backwashing removes accumulated solids

Because DMI-65® enhances oxidation, lower chemical doses are required compared to conventional sand or greensand filters.

DMI-65® for Deep Well Rehabilitation Projects

Deep well rehabilitation aims to restore well performance, water quality, and operational efficiency without excessive downtime or structural damage.

Benefits of Using DMI-65® in Well Rehab:

• Removes dissolved iron and manganese before biofouling develops

• Reduces iron bacteria growth

• Minimizes chemical shock treatments

• Improves well yield and pump efficiency

• Extends the lifespan of well infrastructure

In many projects, installing a DMI-65® filtration system downstream of the wellhead prevents recurring contamination issues that typically lead to repeated rehabilitation cycles.

Advantages of DMI-65® in Groundwater Treatment Applications

1. Superior Iron & Manganese Removal

DMI-65® can treat high concentrations of iron and manganese commonly found in deep aquifers, even at variable pH levels.

2. Low Chemical Consumption

The catalytic nature of DMI-65® reduces oxidant demand, lowering operating costs and chemical handling risks.

3. Ideal for Remote & Municipal Systems

With minimal maintenance requirements, DMI-65® is ideal for remote well sites, rural water supplies, and municipal groundwater treatment plants.

4. Long-Term Cost Efficiency

Its durability and extended media life reduce replacement frequency and lifecycle costs.

Typical Applications for DMI-65® Water Treatment

• Deep well rehabilitation projects

• Municipal groundwater treatment plants

• Industrial process water systems

• Mining and resource sector water supply

• Agricultural & irrigation wells

• Drinking water treatment for rural communities

Sustainable Groundwater Treatment with DMI-65®

As regulations increase and sustainability becomes a priority, water utilities and engineers are seeking treatment solutions that minimize chemical use and environmental impact. DMI-65® supports sustainable groundwater treatment by:

• Reducing chemical consumption

• Limiting waste generation

• Enhancing system efficiency

• Protecting aquifer integrity

This aligns well with modern water management strategies focused on long-term resource protection.
