Water deiovizin'j system in Pent American World Airways hangar at Idlewild.
Amberlite-deionized water boosts jet takeoff power Pan American Jet Clipper^ faking off with aid of water injection.
Injecting water into a Pratt & Whitney J-57 jet engine at takeoff adds mass to the exhaust gases and increases thrust so that Pan American Jet Clippers equipped with these engines can step up their takeoff loads as much as 18 percent. However, the water used must have an extremely low level of dissolved solids. Impurities can cause deposits on jet turbine blades, reduce critical clearances, and necessitate costly and time-consuming overhaul jobs. To supply water for these jets, Pan American World Airways operates AMBERLiTE-equipped water-deionizing units at both the Azores and Idlewild. Each unit consists of two tanks, 8 feet tall. One tank contains 20 cubic feet of AMBERLITE IR-120 cation exchange resin; the other, an equal amount of AMBERLITE IRA-400 for anion removal. These deionization systems are capable of supplying water with an average solids content of 1.5 ppm, at the rate of 100 gallons per minute, and operate for several weeks at a time without attention. Regeneration of
either of these systems requires about two hours, and is accomplished entirely by valve manipulation. ion exchange resins provide efficient service wherever water has to be softened, deionized, dealkalized or deacidified. Industrial uses include applications concerned with power generation, recovery of metal ions, processing of pharmaceuticals, catalysis, sugar refining, and analytical chemistry.
