Sample interview questions: How do you approach system water treatment and biofilm prevention in hydronic applications?
Sample answer:
- Water Testing:
-
Conduct thorough water analysis to determine factors like pH, alkalinity, hardness, and presence of bacteria and other contaminants. This information helps tailor the treatment program.
-
Inhibitors and Chemicals:
-
Utilize suitable inhibitors and chemicals specific to the system and water conditions. These include corrosion inhibitors, oxygen scavengers, biocides, and antifreeze solutions.
-
System Flushing:
-
Perform a thorough system flush to remove existing debris, sediment, and contaminants. This helps establish a clean base for the treatment program.
-
Filtration:
-
Install filtration systems to remove particles, sediment, and other contaminants from the water. This helps prevent the formation of biofilm and corrosion.
-
Regular Maintenance:
-
Conduct routine maintenance, including system inspections, filter cleaning or replacement, and water testing. This helps identify potential issues early and ensures the continued effectiveness of the treatment program.
-
Biofilm Prevention:
-
Implement strategies to prevent biofilm formation, including:
- Maintaining proper water chemistry and temperature
- Minimizing the introduction of organic materials into the system
- Using biocides or antimicrobial agents as needed
-
Record Keeping:
-
Maintain detailed record… Read full answer
