ALDEX C-800 Series Resins
C-800F Fine Mesh Water Softening Resin Sodium Form
NSF/ANSI 44, 61 and 372 Certified. Aldex C-800F is a high quality, gel-type, high capacity fine mesh cation resin for use in most domestic and industrial water softening applications. Aldex C-800F resin has far more surface area per square foot than typical water softening resin. The result is faster kinetics and more ion exchange capacity per regeneration, using similar amounts of salt.

No Chlorinated Solvents
The absence of chlorinated solvents in the manufacturing of Aldex C-800F results in very low TOC leakage.
Very low color, taste or odor
Aldex C-800F meets the requirements for paragraph 173.25 of the Food Additive Regulation of the U.S. Food and Drug Administration.
Over 34 years of actual field usage by thousands of customers demonstrates the reliability of Aldex C-800.
Advantages of Fine Mesh Resin
• Highest capacity / long service cycles
• Minimum salt usage
• Low backwash rates
• Shorter regeneration times
• Reduced rinse water
• Increased removal of ferrous iron
A material safety data sheet is available for Aldex C-800F. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800F is not a hazardous product and is not WHMIS controlled.
Caution: Acidic and basic regenerant solutions are corrosive and should be handled in a manner that will prevent eye and skin contact. Before using strong oxidizing agents in contact with ion exchange resin, consult sources knowledgeable in the handling of these materials.
C-800F Operating Suggestions
In most cases Aldex C-800F will remove more iron from water than the Aldex C-800.
At normal service flow rates, Aldex C-800F will have less hardness leakage than Aldex C-800, however, the hardness leakage will be greater at the higher flow rates, especially those encountered in some dishwashing applications.
Pressure Drop Considerations
The pressure drop across a bed of Aldex C-800F will be from 2.5 to 4.0 times what it would be for Aldex C800 for any given conditions of flow rate and temperature. Insure the underdrain system can accommodate this increase in pressure drop or modify accordingly.
Several factors can influence the operating or working capacity of Aldex C-800F find mesh resin, therefore, it is not possible in this bulletin to predict exactly what the operating capacity of Aldex C-800F will be. Factors which influence capacity include: cocurrent vs countercurrent regeneration, high service flow rates vs low flow rates, regeneration and salt dosage. Generally speaking the operating capacity of Aldex C-800F will be approximately 10% higher than standard mesh softener resin in most applications when both are used under the same conditions.
To reclassify the beads and remove suspended solids from the top of the bed, the resin bed should be expanded at least 50% according to Fig. 2 by backwashing for at least five minutes or until the backwash water is clear. The above may not be necessary in the case of upload regenerated softeners since the backwash and brine injection are incorporated in the same step.
