converting salts present into corresponding acids. Then these acids are removed from solution by De-Acidite*, Permutit's resin-type anion exchanger.

Many important applications have been found for these ion exchange processes outside the field of water condi tioning. They are useful in sugar manufacturing, in recovering tartaric acid from waste products, in produc ing purer pectin by an economical process from citrus peels, in recovering valuable metals from solutions, etc. W r i t e for free bulletin "Ion Exchange i n the Process Industries."

Here's a process that removes all salts from water sup plies. T h a t means that the water produced can be used in m a n y applications formerly requiring distilled water. Y e t the cost of producing this Permutit* Demineralized Water is, on most waters, as low as 5 to 15 cents per 1000 gallons—.2 small fraction of the cost of distillation/ In t h e Demineralizing process, Zeo-Karb* H, Permutit's acid-regenerated organic cation exchanger, re places metallic cations in the water w i t h hydrogen ion,
