Water-based anticorrosion methods |
| abstract |
(57) [PROBLEMS] To provide a water-based replenishing water or retained water by ion-exchange treatment to remove a part of corrosive ions and silica and / or Ca ions and control the concentration to an appropriate concentration. In the method for preventing corrosion and scale failure, the size of the apparatus for ion exchange is reduced to reduce the labor for regeneration, the amount of chemicals, the amount of drainage, and the like. SOLUTION: Ca ions are removed by a cation exchange resin, and silica and corrosive ions are removed by an anion exchange resin. Water supply is continued even after the point of flow of silica of the anion exchange resin or after the point of flow of Ca ions of the cation exchange resin until the silica concentration or the average value of the Ca ion concentration reaches a predetermined value. [Effect] By supplying the treated water before the once-through point and the treated water after the once-through point, it is possible to supply water having an appropriate silica concentration or Ca ion concentration in one anion exchange column or cation exchange column. it can. |
