The Culligan Soft Water Service Company Deionizer and Carbon Exchange tanks are primary or temporary devices to provide water for hemodialysis applications per the requirements of ANSI/AAMI RD62. These tanks remove chlorine, chloramines, total organic carbons and total dissolved solids from water used to dilute dialysis concentrate to form dialysate, in reprocessing of hemodialyzers, as supply water to the dialysis machines and equipment rinse and disinfection. Upon exhaustion, these tanks will be replaced with other tanks containing newly regenerated resin, or with new resin altogether. These tanks are components of a larger water treatment system employing adequate pre-treatment and post-treatment sections. Culligan's tanks are not to be used alone.
