Sample interview questions: Can you explain the role of water treatment technicians in preventing the formation of disinfection byproducts?
Sample answer:
Role of Water Treatment Technicians in Preventing Disinfection Byproduct (DBP) Formation:
1. Process Optimization:
- Monitor water quality parameters to identify conditions that promote DBP formation (e.g., high organic matter, pH, temperature).
- Adjust treatment processes (e.g., pH adjustment, coagulation, disinfection type) to minimize DBP precursors.
2. Alternative Disinfection Methods:
- Explore and implement advanced disinfection technologies (e.g., chloramines, chlorine dioxide) that produce fewer DBPs compared to traditional chlorine disinfection.
3. Precursor Removal:
- Employ advanced treatment techniques (e.g., granular activated carbon adsorption, ozonation) to remove organic matter and other DBP precursors from the water source.
4. Monitoring and Control:
- Regularly monitor DBP levels to ensure compliance with regulations and minimize public health risks.
- Implement control measures such as blending treated water with untreated water to reduce overall … Read full answer
