It takes a lot of water to r u n a paper mill, not only as an actual ingredient in paper making, but also for the steam necessary for power generation and for cooling paper machine condensate. At Minnesota and Ontario Paper Company in International Fails, lviiinicsuu* he feed water to the boiler— rated a t 240,000 lbs. pe -, 1290 psig.—mu?t be deionized. This is accomplk y passing the feed water r through 1) two parallel ht AMBERLITE IR-120, a strongly acidic cation exchan^.. resin operating in the hydrogen cycle, 2) a vacuum deaerator, 3) and through two parallel beds of AMBERLITE IRA-400, a strongly basic anion exchange resin. T h e water has a conductivity of only 1.5 to 3 micromhos, with a silica content of less trjan .015 ppm. Deionized water requirements vary from 100 to 300 gallons per minute.
