Top 10 Questions for De-Ionizer Operator Interview

Essential Interview Questions For De-Ionizer Operator

1. Explain the process of deionization.

  • Deionization is a process that removes ions from water by passing it through a series of ion exchange resins.
  • These resins are made of small beads that are covered in charged ions.
  • As water passes through the resins, the ions in the water are attracted to the oppositely charged ions on the resins and are exchanged.
  • This process continues until all of the ions have been removed from the water.

2. What are the different types of deionizers?

Ion exchange resins

  • Anion exchange resin removes negatively charged ions, such as chloride and sulfate.
  • Cation exchange resin removes positively charged ions, such as sodium and calcium.

Electrodeionization (EDI)

  • EDI uses an electric current to remove ions from water.
  • This process is more efficient than ion exchange resins, but it is also more expensive.

3. What are the applications of deionized water?

  • Deionized water is used in a variety of applications, including:
  • Semiconductor manufacturing
  • Pharmaceutical manufacturing
  • Laboratory testing
  • Power generation
