ResinTech - Model SIR-900 -Granular Aluminum Oxide Based Adsorbent
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.

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.
Fluoride Removal
Fluoride is removed by ResisinTech SIR-900 by a chemical reaction which is flow and pH sensitive. The best results are obtained when the flow is limited to about 1 gpm/cu.ft. and the pH is held at 5.5. Higher flows and higher or lower pH results in loss of capacity. Leakage of fluoride is generally less than 0.1 mg/L to breakthrough. SIR-900 can be regenerated with sodium hydroxide, followed by neutralization with acid at a pH of 5-6.
Arsenic Removal
Inorganic arsenic (arsenate) can be removed by ResisinTech SIR-900. The process is pH sensitive and capacity decreases when the pH is below 5.5 or above 6.O. Arsenite is not removed nearly as well as arsenate, therefore pre-oxidation may be required.
Lead Removal
Dissolved lead is adsorbed by ResisinTech SIR-900. This process is not dramatically affected by flow rate, temperature or TDS. However, pH should be maintained above 6.0 as lead removal drops under acidic conditions, and below 10 as lead precipitates under basic conditions.
