ResinTech SBG1P-OH, Porous Strong Base Anion Exchange Resin, OH Form, 1 Cubic Foot
ResinTech SBG1 is a chloride form type 1 porous gel strong base anion resin. SBG1P has higher moisture content and lower ion exchange density that SBG1. This results in higher operating capacity, better chemical efficiency and improved resistance to fouling. SBG1P 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. SBG1P-OH is especially well suited for use in working mixed beds.
Features & Benefits
- High Operating Capacity: High porosity type 1 anion provides high regeneration efficiency and high throughput per pound of caustic regenerant
- Organic Fouling Resistance: Porous structure allows greater elution of organic molecules during regeneration
- Superior Physical Stability: 93% plus sphericity and high crush strengths together with carefully controlled particle distribution provides long life and low pressure drop
- Complies With US FDA Regulations: Conforms to paragraph 21CFR173.25 of the Food Additives Regulations of the US FDA
Applications:
- Demineralization: ResinTech SBG1P-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. Common configurations include separate beds, mixed beds and other more complicated arrangements.
- Desilicizer SBG1P-OH can be used following a water softener as a desilicizer to remove silica along with other anions. Regeneration is accomplished with sodium hydroxide. Feed water must be softened to prevent hardness scaling of the resin. This process removes all bulk anions and replaces them with hydroxides, increasing both the pH and alkalinity. This limits the applicability to waters with low or modest TDS.
