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.
