TI  - A study on stack configuration of continuous electrodeionization for removal of 
      heavy metal ions from the primary coolant of a nuclear power plant.

AB  - This study investigated the production of high-purity water in the primary 
      coolant of a nuclear power plant via the continuous electrodeionization (CEDI) 
      process, using ion exchange resins as ion-conducting media between ion exchange 
      membranes. The effectiveness of this method was examined with respect to the 
      removal of heavy metals. The study was carried out on a laboratory scale with an 
      effective area of 20 cm(2). The CEDI system was operated with a layered bed of 
      cation exchange resins, anion exchange resins, and mixed-bed ion exchange resins. 
      The stack configuration was designed to prevent a reaction between metal ions and 
      hydroxide ions. The CEDI operation with the layered bed removed more than 99% of 
      the ions at 30% of the current efficiency. The results showed that, with an inlet 
      conductivity of 40 microScm(-1), a linear velocity of 4.17 cms(-1), and an 
      applied current density of 17 mAcm(-2), the CEDI process yielded an outlet 
      conductivity of 0.5 microScm(-1), thereby preventing the precipitation of metal 
      ions. This study therefore successfully demonstrated the feasibility of the CEDI 
      operation for the removal of heavy metals at a very low concentration.
