Document Type and Number:
WIPO Patent Application WO/2011/001871
Kind Code:
A1
Abstract:
A process for producing an ion-exchange device is provided in which ion-exchange resins are prevented from being fouled by airborne dust. An anion-exchange resin and a cation-exchange resin are purified and metered respectively through receiving tanks (11, 21), purification columns (14, 24), storage tanks (16, 26), and metering tanks (19, 29), mixed together in a mixing tank (30), and then filled into a vessel (33). The metering tanks (19, 29), the mixing tank (30), and the vessel to be filled (33) are disposed in a clean room (41) having a degree of cleanliness of 10,000 or higher. The produced ion-exchange device is subjected to a water-passing test, and the effluent water is analyzed in a high-cleanliness clean room (42) having a degree of cleanliness of 1,000 or higher.
