Sample answer:
Steps to Handle Excessive Chemical Usage in Water Treatment Systems:
-
Identify the Root Cause:
- Perform thorough system inspection to assess chemical consumption patterns and identify potential leaks, malfunctions, or improper settings.
- Analyze influent and effluent water samples to determine if excessive chemical usage is due to increased contaminant levels or inefficiencies in the treatment process.
-
Optimize System Performance:
- Adjust chemical feed rates and timing based on influent water analysis and system design specifications.
- Calibrate sensors and controllers to ensure accurate chemical dosing.
- Clean or replace filters, membranes, or other components as needed to improve treatment efficiency.
-
Investigate Potential Contamination:
- Conduct site surveys to identify potential sources of chemical contamination in the feed water, such as industrial discharges or agricultural runoff.
- Implement appropriate pretreatment measu… Read full answer
