ResinTech ASM-10-HP Arsenic Reduction Resin, 1 Cubic Foot
ResinTech ASM-10-HP is a chloride form arsenic selective hybrid anion exchange resin. ASM-10-HP has hydrated iron oxide monoatomically dispersed throughout the polymer. It captures arsenate first by ion exchange and then by absorption into the iron oxide hybrid. ASM-10-HP is intended for arsenic removal from potable water, and can be also be used as an ion exchanger for removal of uranium and other trace level contaminants.
Features & Benefits
Physical PropertiesFeatures & Benefits
- High Affinity For Arsenic Over Other Anions: Highest arsenic removal capacity of any organic based arsenic removal media
- No Arsenic Dumping: Effluent arsenic levels will not exceed influent levels if resin is operated past exhaustion point
- Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA
Applications:
- Arsenic Removal: Under ideal conditions, ASM-10-HP will reduce 50 ppb of arsenate to less than 10 ppb for more than 500,000 gallons per cubic foot. Limiting factors are high pH, high silica concentration, and high sulfate concentration. Capacity can also be reduced by intermittent operation and various foulants, notably suspended solids.
- Silica Removal: ASM-10-HP can be used at moderate pH to remove silica. At a flow rate of 0.5 BV/min, removal efficiency of 90% is possible for several hundred bed volumes of throughput. Silica does not dump as the resin exhausts. Even though silica removal is not complete, some lowering of silica occurs for hundred of thousands of bed volumes.
