ResinTech SIR-1300 is a hybrid ion exchange resin media with catalytic properties to remove dissolved iron, manganese and hydrogen sulfide from potable and non-potable water. SIR-1300 oxidizes dissolved ferrous iron (FE2+) to insoluble ferric iron (FE3+). Similarly soluble Mn2+ will be converted to insoluble Mn3+. H2S is reduced to yellow sulfur particulate. A secondary mechanism of SIR-1300 is Arsenic Reduction. As Iron is loaded onto the bed, Arsenic is co-precipitated as ferric arsenate. The resulting insoluble Iron, Mn, sulfur and arsenate particulates are effectively removed via filtration. The accumulated particulates can be removed with simple backwash and air scour.
