ResinTech CG8 8% Crosslinked Cation Exchange Resin, H Form, 1 Cubic Foot
ResinTech CG8 is an 8% cross linked gel strong acid cation resin. CG8 is a workhorse cation resin optimized for industrial and residential applications that require good regeneration efficiency and oxidative stability. ResinTech CG8 is intended for use in all industrial and commercial softening applications as well as residential applications that have moderate amounts of chlorine in the feedwater. CG8-H is intended for use in demineralizes and in mixed beds.
Features & Benefits
- Industrial Softening and Demineralizing Applications: 8% DVB cross linking is ideal for most industrial applications
- Low Color Thow
- 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:
- Softening: ResinTech CG8 is an 8% crosslinked cation resin optimized for residential and commercial applications.
- Demineralization: ResinTech CG8-H can be used as the cation component in a separate bed and mixed bed demineralization applications where a hydrogen form cation resin is coupled with a hydroxide form anion resin. Regeneration is accomplished with stepwise sulfuric acid or with hydrochloric acid.
- Iron Removal: CG8 has good capacity for ferrous iron. Iron content in the feed water should not be more the 1 mg/L Fe per each 17 mg/L of hardness.
- Ammonia Removal: ResinTech CG8 is slightly selective for ammonia compared to sodium but hardness is much more preferred. Ammonia is not ionized at pH above 9 and is not well removed when the pH is significantly alkaline
