ResinTech SBG1-OH Strong Base Anion Exchange Resin, OH Form, Semiconductor Grade, 1 Cubic Foot

ResinTech SBG1 is a chloride form type 1 gel strong base anion resin. SBG1 is a high crosslinked resin with higher ion exchange density than other strong base anion resins. This results in both higher capacity and higher selectivity for various anions. ResinTech SBG1 is intended for use in the hydroxide form for all types of deionizing systems as well as in the chloride form for removal of contaminants such as nitrate, arsenate, chromate, uranium, etc. SBG1-OH is especially well suited for use in polishing mixed beds.

Features & Benefits
     - High Total Capacity: Provides long run lengths
     - Lower TOC Leach Rate: Ideal for use in polishing mixed beds when ordered in the hydroxide form
     - Superior Physical Stability: 93% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
     - Controlled Particle Size: 16 to 50 mesh size provides a low pressure drop and superior kinetics
     - Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA

Applications:
     - Demineralization: ResinTech SBG1-OH can be used as the anion component in a variety of demineralization applications where a hydroxide form anion resin is coupled with a hydrogen form cation resin. SBG1-OH is suitable for high operating temperatuers and for high flow rates encountered in polishing condensate and other low TDS waters such as RO permeate. SBG1-OH provides low TOC and low silica leakage in ultrapure demineralizers.
     - Trace Contaminant Removal: ResinTech SBG1 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.
     - Nitrate Removal: SBG1 cab be used in the chloride cycle to reduce nitrates along with sulfates. Regeneration is accomplished with sodium chloride brine, in a fashion similar to water softeners. Although high operating capacities and high salt efficiency can be obtained, there is also the possibility of nitrate dumping. Use of chloride form anion resin reduces pH during the early portion of the exhaustion cycle. When treating waters with high hardness the brine dilution and displacement waters should be softened and a low hardness salt used to prevent scaling during regeneration.
     - Sulfate Removal: High capacity resins such as ResinTech SBG1 have high affinity for divalent anions such as sulfate, provided the feedwater TDS is not greater than about 5,000 ppm. At higher TDS the resin loses its affinity for sulfate and begins to prefer chloride. Regeneration is accomplished with sodium chloride brine in a fashion similar to a water softener.
