ResinTech SIR-500, Copper & Nickel Selective Cation Resin, 1 Cubic Foot

ResinTech SI R-500 is a sodium form macroporous chelating weak acid cation resin. SIR-500 has unique aminophosphonic chelating functionality and is particularly selective for alkaline earth metals such as calcium. ResinTech SIR-500 is intended for removal of hardness from saturated brine and for removal of divalent metals such as copper and nickel from wastewater and various process streams.

     - Removes Calcium and Magnesium From Brine Solutions: Ideal for removing hardness from brine solutions under neutral to alkaline conditions

     - Removes Heavy Metal Cations From Process Solutions: High Capacity for removing traces of heavy metals from process waters even in the presence of hardness ions

     - Superior Physical Stability: 95% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
     - Controlled Particle Size: 16 to 50 mesh size provides a low pressure drop and superior kinetics

    

     - Brine Softening: ResinTech SIR-500 is ideally suited to remove traces of hardness from saturated brines, as pretreatment to electrolysis cells as well as other applications for brines that require low levels of divalent metals. SIR-500 works best at relatively alkaline pH following chemical precipitation processes. All chelating resins are kinetically limited and require a low flow rate. Elevated temperatures improve kinetics provided the resin is not operated beyond its stated thermal limits. To avoid excessive bead breakage, care must be taken to “sweeten on“ and “sweeten off” to avoid thermal and osmotic shock from occurring.
     - Trace Metals Removal: ResinTech SIR-500 can be used to remove heavy metal multivalent ions from a variety of industrial effluents like oil refineries, plating shops, mine drainage, battery manufacturers, cooling towers etc.
