C-800H UPS Features

Elemental analysis, dry basis

Sodium (Na)<100 ppm
Cobalt (Co)<50 ppm
Copper (Cu)<50 ppm
Aluminum (Al) <50 ppm
Iron (Fe) <50 ppm

Very Low TOC

Non solvent sulfonation and special manufacturing processes assure very low TOC leakage.

Uniform Particle Size

99% of all beads are in the minus 16 to plus 40 mesh range: giving a lower pressure drop while maintaining the superior kinetics of standard mesh size products.

Superior Physical Stability

90% plus sphericity and high crush strengths together with a very uniform particle size provide greater resistance to bead breakages and maintaining low pressure drops.

Reliability

Aldex Chemical has over 40 years of field usage by thousands of customers demonstrate the reliability of Aldex ion exchange resins, zeolites and other water treatment media.

 

Safety Information

A material safety data sheet is available for Aldex C-800H UPS. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800H UPS 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.

 

Backwash Characteristics

Aldex C-800H UPS should be backwashed for at least 10 minutes after each service cycle in a conventional down flow regenerate unit. 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 1.

In case of non-conventional or upflow regenerated units, it may not be necessary to follow the above procedure.

Operating Capacity

The following table (Fig 3.) shows the hydrogen cycle relationship between operating capacity and regeneration level when using sulfuric acid as the regenerant.

The calcium data is based on an acid concentration of 2% in order to avoid calcium sulfate precipitation. Higher operation capacities could be obtained using a step wise increase in acid concentration to avoid the calcium problem. For more information please contact our technical department.
