Description

The 8″ Diameter DMI-65 Iron Removal System with an Automatic Backwash Head is a premium water treatment solution designed to efficiently remove dissolved iron, manganese, and hydrogen sulphide from borehole, well, and municipal water supplies. Combining advanced DMI-65 catalytic filtration media with a heavy-duty FRP (Fibreglass Reinforced Plastic) pressure vessel and a fully automatic backwash control valve, this system delivers reliable, high-performance filtration with minimal operator intervention.

Excessive iron and manganese in water can cause reddish-brown staining on sanitary ware, laundry, paving, and fixtures while producing unpleasant metallic tastes and odours. These contaminants also accumulate inside plumbing systems, pumps, water heaters, and downstream filtration equipment, reducing efficiency and increasing maintenance costs. Hydrogen sulphide, commonly recognised by its “rotten egg” smell, can further affect water quality and user satisfaction.

The DMI-65 filtration media has been specifically developed to provide exceptional catalytic oxidation of dissolved iron and manganese, allowing these contaminants to be converted into insoluble particles that are trapped within the media bed. Under the correct operating conditions, DMI-65 offers outstanding filtration performance, excellent durability, and an extended service life, making it one of the most effective iron removal media available.

Unlike manually operated systems, this model features an automatic backwash control head that is programmable to clean the filter media at predetermined intervals. During the automatic backwash cycle, accumulated contaminants are flushed from the media bed, restoring filtration efficiency without requiring manual operation. This ensures consistent water quality while reducing maintenance and making the system ideal for installations where convenience, reliability, and continuous operation are priorities.

The corrosion-resistant FRP pressure vessel is lightweight, robust, and engineered for long-term performance in demanding residential, commercial, agricultural, and industrial environments. Its compact 8-inch diameter design allows for easy installation where space is limited while still providing excellent filtration efficiency.

Whether protecting a family home supplied by borehole water, improving water quality for a commercial facility, or serving as a pre-treatment stage before a Reverse Osmosis system, the 8 ″ Diameter DMI-65 Iron Removal System with an Automatic Backwash Head provides dependable, fully automated water treatment that improves water quality, protects valuable equipment, and reduces ongoing maintenance.

How the System Works:

Raw water enters the FRP pressure vessel and flows through the specially engineered DMI-65 catalytic media. As the water passes through the media bed, dissolved iron and manganese are oxidised into solid particles that are captured within the filter media. Clean, treated water then exits the vessel for distribution throughout the property.

The automatic control valve continuously monitors the programmed backwash schedule and automatically initiates cleaning cycles when required. During backwashing, the direction of water flow is reversed, flushing accumulated contaminants from the media bed to waste. This process restores filtration efficiency and ensures consistent system performance without manual intervention.

Automatic backwashing significantly reduces maintenance while providing dependable filtration around the clock.
