ResinTech RSM-25-HP Radium Selective Cation Resin, 1 Cubic Foot

     - Superior Radium Removal Capacity: Can be used for one-time use or regenerable applications

     - Unique Polymer Structure: Unique highly crosslinked polymer structure provides greatly increased capacity for radium compared to other cation resins

     - Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA

     - Radium Removal Single Use: RSM-25 is supplied in the sodium form. During the initial portion of the service cycle the resin functions as a softener because it removes hardness along with radium. RSM-25 will continue to remove radium in this fashion for many times the volume of its softening capacity. For this reason, RSM-25 is widely used in single cycle applications for removing radium from potable waters with low to medium hardness. RSM-25 is not affected by pH nor is capacity reduced by the presence of sulfate or other common ions. RSM-25 does not contain barium.

     - Radium Removal Multiple Cylce Use: RSM-25 may be regenerated and reused over many hundreds of exhaustion and regeneration cycles. It is ordinarily regenerated with sodium chloride but other regenerants such as potassium chloride can be used. Because it is difficult to remove all the radium during regeneration, the throughput in regenerable applications is limited to softening capacity.
