No Chlorinated Solvents
The absence of chlorinated solvents in the manufacturing of Aldex C-820 results in very low TOC leakage.
Very low color, taste or odor
Aldex C-820 meets the requirements for paragraph 173.25 of the Food Additive Regulation of the U.S. Food and Drug Administration.
High Capacity
30,000 grains of softening capacity when regenerated with 15 lbs of NaCl per cubic. ft. and 20,000 grains with 6 lbs of NaCl per cubic.ft. ensuring high efficiency and low operating costs.
Long Life
Strong and durable beads insure long service life.
Reliability
Over 34 years of actual field usage by thousands of customers demonstrate the reliability of Aldex C-820.

Iron
Aldex C-820 will remove most of the dissolved iron, can filter much of the suspended iron and may or may not remove organically bound iron from water. When softeners are used to remove iron from the water, periodic cleaning of the bed mechanically or with a chemical iron cleaner may be necessary.
Chlorine
All cation exchange resins are affected by chlorine and suffer degradation and swelling. It is recommended that the chlorine in the water be maintained below 1.0 ppm when using Aldex C-820.

Backwash Characteristics
Aldex C-820 should be backwashed for at least 10 minutes after each service cycle in a conventionally down flow regenerated softener. 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.
In the case of non-conventional or upflow regenerated softeners, it may not be necessary to follow the above procedure since the backwash and brine injection are incorporated in the same step.

Safety & Health
- Safety Information
A material safety data sheet is available for Aldex C-820. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-820 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.
