Aries (AF-20-3001-BB) 20"x4.5" Big Blue Cation Cation (Hydrogen Form) Deionizer
20"x4.5" Big Blue Cation (Hydrogen Form) Deionizer
Specialized ion exchange cartridge that removes dissolved minerals and reduces total dissolved solids through hydrogen form cation exchange for laboratory, pharmaceutical, and ultrapure water applications
Hydrogen form cation exchange resin targets positively charged dissolved minerals
Cation Exchange Technology
Hydrogen form resin exchanges cations like calcium, magnesium, sodium, and iron with hydrogen ions, converting dissolved salts into weak acids
TDS Reduction
Effectively removes dissolved ionic contaminants to produce low-conductivity water for specialized applications requiring mineral-free feed water
Laboratory Grade
Designed for applications demanding precise mineral removal including ultrapure water prep, pharmaceutical processing, and analytical laboratory work
Big Blue Compatibility
Standard 20"x4.5" dimensions fit all Big Blue housings for easy integration into existing ultrapure water systems
Fits standard 20-inch Big Blue filter housings
The Aries AF-20-3001-BB cartridge fits all standard 20" Big Blue filter housings with 4.5" diameter capacity. Compatible with Pentek, Hydronix, Culligan, Liquatec, and other brands using the 20x4.5 Big Blue format. Requires housing capable of handling deionization applications. Often used in series with anion DI cartridges or as polishing stage after RO membranes.
Replacement schedule depends on feed water TDS and throughput
Watch Effluent Quality
Replace when output water conductivity rises or TDS readings increase, indicating resin exhaustion
Typical Service Life
Lifespan varies widely based on input water quality and volume treated. High TDS feed water exhausts resin faster
Pre-Treatment Required
Install after sediment and carbon filtration and ideally after RO membrane to extend service life and prevent fouling
Specialized TDS Control
Targets cations specifically for ultrapure water applications where mineral removal is critical
Process Flexibility
Use alone for cation removal or combine with anion cartridges for full mixed bed deionization
Industrial Quality
Aries Filter Works manufactures specialty cartridges for demanding commercial and laboratory environments
Direct Integration
Standard Big Blue sizing means simple drop-in installation with no system modifications required
