Description
ResinTech CG8 is a dark colored 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-BL 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-BL 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-BL is an 8% crosslinked cation resin optimized for residential and commercial applications. – Demineralization: ResinTech CG8-BL 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-BL 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-BL 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
