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 maintain low-pressure drops.
Safety Information
A material safety data sheet is available for Aldex C-800H. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800H 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 should be backwashed for at least 10 minutes after each service cycle in a conventional downflow 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 the case of non-conventional or upflow regenerated units, it may not be necessary to follow the above procedure.
Pressure Drop
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% 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.
