THERE ARE M A N Y PROFITABLE NEW USES FOR ION E X C H A N G E — B E S I D E S WATER C O N D I T I O N I N G
ew applications of old principles make it possible M for you to recover from solutions many substances
For Instance:
METAL RECOVERY. An improved process permits economical recovery of a variety of metals, such as copper, zinc, and nickel, from solutions which previously constituted a serious waste disposal problem. A variety of ion exchange techniques permits recovery in a form which is immediately useful, and the disposal of the remaining solution is more easily accomplished*.
PHOSPHORIC ACID PICKLING. A new process, by reclaiming the acid for further use, makes phosphoric acid pickling no more expensive than sulphuric acid pickling. Corrosion of surroundings is eliminated and a desirable phosphate coating is produced. Iron loss is reduced.
® T h e s e are only a few of the new developments in ion exchange. Permutit has been the sole maker of all types o f ion exchange equipment and minerals for 38 years. For further details, write to T h e Permutit Company, D e p t . C N - 9 , 3 3 0 West 4 2 n d Street, N e w York 1 8 , Ν.

which usually are wasted. Permutit's new ion exchange processes turn waste into profit, reduce operating cost, and eliminate many waste disposal problems.
CHROMIC ACID PURIFICATION. A n o t h e r new p r o c e s s saves up to 90% of the chromic acid used in metal treating applications because Permutit Q removes impurities from the bath solution. No wasteful dumping is necessary. Permutit S prevents waste by saving the chromâtes in the rinse water, for conversion to free chromic acid
