INDION® ISR is a specially developed catalytic filtration media designed for the efficient removal of dissolved iron from groundwater. Unlike conventional ion exchange resins, INDION® ISR is an insoluble catalytic media that oxidizes dissolved ferrous iron (Fe²⁺) into insoluble ferric iron (Fe³⁺), which is then retained within the media bed and removed during backwashing.

The media serves both as a catalyst and a filtration medium, eliminating the need for chemical regeneration. With its spherical bead structure, excellent catalytic activity, and simple water backwash regeneration, INDION® ISR is ideal for borewell water treatment, iron removal plants, and pretreatment systems for RO and ion exchange plants.

💧 Key Benefits

Efficiently removes dissolved ferrous iron from groundwater.
Catalytic action provides long service life without chemical regeneration.
Functions as both an oxidation catalyst and filtration media.
Water backwash alone restores filtration efficiency.
Faster catalytic activity requires less contact time and reduced bed depth.
Low compaction minimizes pressure loss across the filter bed.
Performs effectively over a wide operating temperature range.
Suitable for treating high-TDS groundwater with relatively low alkalinity.
Media can be removed, cleaned, and reused without clinker formation.
Ideal for point-of-use (POU) and industrial iron removal systems.

🔧 Installation & Operating Guidelines

Rinse the media with at least 10 bed volumes of demineralized water before initial service.
Feed water should contain less than 10 ppm suspended solids; pretreatment is recommended if suspended solids are higher.
Remove free chlorine before the water enters the media bed.
Maintain the recommended service and backwash flow rates for optimum performance.
For feed iron concentrations around 10 ppm, use treated water for backwashing to prevent contamination of the lower bed.
Backwash the media at the specified flow rate to effectively remove precipitated iron and prevent media choking.
Continuous operation should include backwashing approximately every 12 hours, while intermittently operated systems should limit service cycles to 5–6 hours before backwashing.

⚙️ How It Works

INDION® ISR removes dissolved ferrous iron (Fe²⁺) through catalytic oxidation. As groundwater passes through the media bed, the catalytic surface rapidly converts soluble ferrous iron into insoluble ferric iron (Fe³⁺). These ferric iron particles become trapped within the media bed while the treated water passes through.

Unlike conventional iron removal media requiring chemical regeneration, INDION® ISR restores its filtration capacity through a simple water backwash that removes accumulated iron particles from the bed. This significantly reduces operating costs and maintenance requirements.

🥽 Safety & Handling

Store the media in its original sealed packaging.
Never allow the media to dry during storage.
Keep the media moist using clean demineralized water if necessary.
Store in a shaded area between 15°C and 45°C.
Handle any oxidizing chemicals with appropriate safety precautions.
Follow standard industrial safety practices during installation and maintenance.

⚠️ Limitations and Precautions

Designed specifically for removing dissolved ferrous iron (Fe²⁺).
Does not effectively remove bacterial iron, soluble organic iron, or colloidal iron.
Feed water should have a pH above 6.5 and adequate dissolved oxygen.
Free chlorine and oil must be absent from the influent.
Water containing more than 10 ppm dissolved iron should be pretreated by aeration, clarification, and filtration before using INDION® ISR as a polishing media.
For RO and ion exchange pretreatment, additional filtration may be required to reduce residual iron below 0.1 ppm.
Polyphosphates and other sequestering agents should be dosed after the INDION® ISR unit.
Proper backwashing is essential to prevent media fouling and maintain catalytic performance.
