Exercise: The Case of the Overflowing Screenings
Scenario: You are a wastewater treatment plant operator. You notice that the screenings washer is struggling to keep up with the volume of screenings, resulting in an overflow and potential safety hazards.
Task:
- Identify three potential causes for the overflowing screenings washer.
- Suggest two practical actions you can take to address the issue and prevent future overflows.
Exercise Correction:
Exercice Correction
**Potential Causes:**
- Increased flow of wastewater into the plant due to rain or industrial discharge
- Malfunction of the screenings screens, allowing more debris to pass through
- A blockage in the screenings washer itself, hindering efficient processing
**Practical Actions:**
- Inspect the screens for damage or clogging and clean or replace them if necessary.
- Check for blockages in the screenings washer and clear them if found. If the blockage persists, contact the manufacturer for technical support.
