ResinTech SIR-900, Lead/Arsenic/Fluoride Removal Media, 1 Cubic Foot
ResinTech SIR-900 is a granular aluminum oxide based adsorbent. SIR-900 is supplied as an active oxide media based on porous aluminum oxide. ResinTech SIR-900 is intended for removal of fluoride from water. It can also be used for the removal of arsenate, selenate, and lead from potable water. SIR-900 is supplied in the activated adsorbent form.
Features & Benefits
- High Affinity For Fluoride: Adsorbs fluoride ions efficiently, especially when pH is slightly acidic
- Multiple Contaminant Removal: Removes a variety of contaminants such as arsenic and lead through a combination of adsorption and chemical reactions
- Superior Physical Stability: Good physical integrity helps minimize breakage and fines formation
- Controlled Granule Size: Large granules provide good physical strength and minimal fines provide low pressure loss
- Controlled Granule Size: Large granules provide good physical strength and minimal fines provide low pressure loss
Applications:
- Trace Contaminant Removal (U, Cr, As, Se, ClO4): ResinTech SIR-1200 has high capacity and can be used to remove a variety of trace contaminants, even when that contaminant is not highly preferred compared to the other bulk ions in the feedwater. Useful capacities are obtained when the feedwater TDS is substantially less than the resin’s internal TDS. Uranium, chromate, and perchlorate are particularly well removed. Arsenate and selenate are well removed but can be chromatographically displaced by sulfate and other ions.
- Radwaste: ResinTech SIR-1200 is ideally suited for radwaste applications requiring the removal of radioactive anions, especially when the feed is significantly
radioactive. The high crosslinking content of SIR-1200 gives it improved resistance to chemical damage caused by ionizing radiation. Structural integrity is maintained up to approximately 1 x 109 rads exposure.
- Precious Metal Removal: ResinTech SIR-1200 has high capacity for precious metals, when those metals are present as anions or as anionic complexes. SIR-1200 will remove traces of precious metal cyanides from plating rinse waters, allowing the recovery of the metal by incineration. Photographic wastes containing silver can be removed and the silver “fixed” to the resin by regeneration with sulfuric acid. Anionic chloride complexes can be removed and then eluted with water.
- Molybdate Removal: ResinTech SI R-1200 has exceptionally high affinity for molybdate ions, even in the presence of substantial concentrations of other ions. Regeneration
is accomplished with sodium chloride brine in a fashion similar to a water softener, or with a variety of other salts such as sodium bicarbonate for applications where an increase in chloride ions is undesirable.
