Sample interview questions: How do you approach system water treatment and scale prevention in hydronic applications?
Sample answer:
System Water Treatment and Scale Prevention in Hydronic Applications
-
Conduct a comprehensive water analysis: Determine the pH, hardness, alkalinity, and dissolved oxygen levels to identify potential treatment needs.
-
Establish appropriate water parameter ranges: Reference industry standards and manufacturer recommendations to set ideal levels for system conditions.
-
Select water treatment chemicals: Choose chemical additives that address specific water quality issues, such as scale inhibitors, corrosion inhibitors, and biocides.
-
Implement proper dosage: Follow manufacturer instructions to ensure that chemicals are added in the correct amounts and at the appropriate intervals.
-
Monitor water quality regularly: Perform regular water testing to monitor water parameters and adjust treatment strategies as needed.
-
Consider scale prevention devices: Install electronic or chemical scale inhibitors to prevent scale formation on heat exchange surfaces.
-
Regularly clean and flush the system: Remove accumulated sediment and debris to prevent scale formation and corrosion.
