Lewatit® S 5221 is a food grade, macroporous, weakly basic anion exchange resin based on a crosslinked

polyacrylate.

Lewatit® S 5221 combines a good physical stability and an excellent resistance to mechanical osmotic

shocks with an exceptionally high total capacity.

Lewatit® S 5221 is suitable in the free base form for the removal of e.g. sulfate ions of organic products

such as lactic acid, citric acid etc.

If using Lewatit® S 5221 to treat potable water and the aqueous solutions listed above, special care should

be given to the initial cycles of the new resin. Please refer to the recommended start-uo conditions available
