<P>PROBLEM TO BE SOLVED: To provide a method of filling a desalting column of a condensed water desalting apparatus with an ion exchange resin capable of obtaining the effect of reducing a PSS (polystyrene sulphonate) concentration in a desired treated water by certainly forming a target ion exchange resin bed of a two-bed form in the desalting column by suppressing the whirling-up of an anion exchange resin from the resin bed formed in the lower part in the desalting column. <P>SOLUTION: In the method of filling a condensed water desalting apparatus with the ion exchange resin, mutually different two upper and lower layers of ion exchange resin beds, which comprise an upper ion exchange resin bed comprising a mixed resin of a cation exchange resin and an anion exchange resin and a lower ion exchange resin bed comprising an anion exchange resin, are formed in the desalting column. In this case, the desalting column is filled with the anion exchange resin along with transfer water to form the lower ion exchange resin bed and, afte water in the desalting column is drained, the desalting column is filled with the mixed resin along with transfer water to form the upper ion exchange resin bed on the lower ion exchange resin bed. <P>COPYRIGHT: (C)2004,JPO |
