ResinTech - Model CG8-UPS - Cation Exchange Resin Uniform Particle Size Strong Acid Gel 8% DVB, Na Or H Form
From Ion Exchange Resins - Uniform Particle Size Resins
ResinTech CG8-UPS is a sodium form 8% crosslinked gel strong acid cation resin. CG8-UPS is a uniform particle size resin with high void space and low coefficient of drag. ResinTech CG8-UPS is intended for use where resin uniformity is an important attribute to help reduce pressure loss or prevent strainer plugging. CG8-UPS is available in the sodium or hydrogen form (when ordered as CG8-H-UPS).

Applications
Softening
ResinTech CG8-UPS is an 8% crosslinked cation resin optimized for industrial softening applications. CG8-UPS has higher total capacity than standard crosslinked resins such as CGS and has higher operating capacity when relatively large brine doses are used during regeneration. CG8-UPS is suitable for hot water applications and for waters that contain modest levels of chlorine.
Demineralization
ResinTech CG8-H-UPS can be used as the cation component in a variety of demineralization applications where a hydrogen form cation resin is coupled with a hydroxide form anion resin. Common configurations include separate beds, mixed beds and other more complicated arrangements. Regeneration is accomplished with stepwise sulfuric acid or with hydrochloric acid.
Packed Beds
ResinTech CG8-UPS has a very narrow particle size range. The uniformity allows a slightly smaller bead size to be used which results in faster exchange of ions, more efficient regeneration and lower leakage. CG8-UPS is ideal for packed beds and other types of countercurrent ion exchangers where consistent operation is important cycle after cycle. Higher void space and minimal fine mesh beads provide low pressure loss and helps prevent channeling and other distribution problems. Packed beds typically have limited freeboard (only a few inches with the resin in the swollen form).
