ResinTech - Model ASM-10 HP - Hybrid Anion Exchange Resin Arsenic Selective Cl Form
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. ResinTech ASM-10-HP is intended for arsenic removal from potable water, and can also be used as an ion exchanger for removal of uranium and other trace level contaminants.

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
Superior Physical Stability
93% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
United States Patent
Method of making and using modified anion exchange materials with metal inside the materials. US Pat. No. 7,504,036.
Complies With US FDA Regulations
Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA.
Under ideal conditions ResinTech 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 intermittant operation and various foulants, notably suspended solids.
ResinTech ASM-10-HP can be used at moderate pH to remove silica. At a flow rate of 0.5 BV/min, removal efficiency of ninety percent 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.
