    Iron Removal Resin - 25L Bag

    INDION ISR is a special media designed to provide excellent catalytic properties to remove dissolved iron from groundwater. INDION ISR is an insoluble media 2+ which oxidizes dissolved ferrous iron (Fe ) to insoluble 3+ ferric iron (Fe ). The insoluble iron thus formed gets trapped in the bed and is effectively filtered. A simple water backwash removes these trapped iron particles from the bed.

    Specifications

     

    Typically for most domestic and commercial situations, the Iron Removal Resin is shipped in 25L Bags. 

    The Bag Dimensions are 35cm x 54cm x 12cm and 19kg**. 

    *Please note that the shipping weight listed below is for a Pallet of Resin, which is only for bulk orders. 

    **Please note that the bag dimensions may differ from Batch to Batch.

    Advantages

    1. The wide particle size range of INDION ISR acts as a filter media, in addition to iron precipitation.
    2. INDION ISR acts as a catalytic media and hence has a longer life.
    3. INDION ISR does not require any chemicals for regeneration. Regeneration is possible with a water backwash.
    4. The catalytic activity is faster in INDION ISR and hence requires less contact time and bed depth. This property makes it the ideal media for POU devices.
    5. Due to spherical beads, the media undergoes less compaction. This leads to less pressure drop across the bed.
    6. Wide temperature range (15 C - 45 C).
    7. Works well at a lower level of alkalinity. This is an advantage when high TDS (>1000 ppm ) water is treated for Iron removal.
    8. No clinker formation and loss of activity due to improper backwash and storage in the vessel. The media can be removed from the vessel, cleaned and reused.

     

    General guidelines for using INDION ISR

    1. It is recommended to rinse the resin with a minimum of 10-bed volumes of DM water before taking it into service.
    2. INDION ISR can be directly used to treat bore well water having suspended solids below 10 ppm. However, pretreatment is required if suspended solids are high.
    3. The media can treat water having an iron content above 10 ppm, but the process is not economical particularly for large flow rates. Hence it is recommended to remove iron by pretreating the water by aeration, followed by clarification and filtration. INDION ISR shall then be used as a polishing media.
    4. Free chlorine should be removed before passing water through the media.
    5. The treated water from INDION ISR will have iron content in the range of 0.1 to 0.3 ppm. The feed water to ion exchange system or RO system requires iron below 0.1 ppm. The iron content of 0.3 ppm can be further reduced to 0.1 ppm and less after passing through a sand filter, carbon filter or any other sediment filter by removal of fine colloidal iron precipitates.
    6. INDION ISR removes dissolved iron from water which is present as ferrous iron. The iron can also exist in other forms such as Bacterial iron, Soluble organic iron, and colloidal iron. This form of iron cannot be removed effectively by INDION ISR.
    7. All the sequestering agents including polyphosphates and meta-phosphates should be added after the INDION ISR unit.
    8. For high iron content in feed water ( around 10 ppm), it is recommended to backwash the unit with treated water, so as to avoid contamination of the bottom portion of the bed.
    9. The unit must be backwashed at a specified flow rate for effective removal of precipitated iron and suspended solids; else it can cause choking of media.
    10. The backwash frequency shall be every 12 hours ( twice a day) for the continuous operating unit. If the unit is operated

     

    Storage

    Ion exchange resins require proper care at all times. The resins must never be allowed to become dry. Regularly open the plastic bags and check the condition of the resin when in storage. If not moist, add enough clean demineralized water and keep it in a completely moist condition. Always keep the resin drum in the shade. Recommended storage temperature is between 15 C and 45 C.

     

    Safety

    Acid and alkali solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. If any oxidizing agents are used necessary safety precautions should be observed to avoid accidents and damage to the resin.
