Ion Exchange INDION® ISR | Iron Specific Catalytic Media

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. 🫗 Quick Highlights Special catalytic media for dissolved iron removal Converts ferrous iron (Fe²⁺) into insoluble ferric iron (Fe³⁺) No chemical regeneration required Regenerates using only water backwash Acts as both catalytic and filtration media Suitable for groundwater and borewell water treatment Low pressure drop due to spherical bead structure Long operational life Suitable for high-TDS groundwater Manufactured by Ion Exchange (India) Ltd.
