C-800 LT Features

Very low color, taste or odor

Aldex C-800 LT 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 foot and 20,000 grains with 6 lbs of NaCl per cubic foot ensuring high efficiency and low operating costs.

Long Life

Strong and durable beads ensure long service life.

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-800 LT. Copies can be obtained from Aldex Chemical Co., LTD. Aldex C-800 LT 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-800 LT Operating Suggestions

Iron

Aldex C-800 LT 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.

*The removal of iron was not evaluated in the WQA certification.

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-800 LT.

Backwash Characteristics

Aldex C-800 LT 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 is incorporated in the same step.
