Exercise on Edge Track
Scenario: You are a water treatment plant operator. You notice that the drum filter in your facility is experiencing decreased filtration efficiency. After inspecting the system, you discover that the filter cloth is sagging and wrinkled.
Task:
- Identify the potential cause of the filter cloth's sagging and wrinkling.
- Explain how the edge track system could be contributing to the issue.
- List at least 3 steps you can take to address this problem and restore optimal filtration efficiency.
Exercice Correction
1. **Potential cause:** The filter cloth's sagging and wrinkling could be caused by a lack of tension, a faulty edge track system, or damage to the filter cloth itself. 2. **Edge track contribution:** The edge track system might be contributing to the problem due to worn-out rollers, improper tensioning, or misalignment of the rollers. This could lead to insufficient tension on the filter cloth, causing it to sag and wrinkle. 3. **Steps to address the problem:** * **Inspect and adjust the tensioning system:** Check if the tensioning system is properly functioning and adjust the tension to ensure the filter cloth is taut and smooth. * **Replace worn-out rollers:** Inspect the rollers for wear and tear and replace them as needed to ensure smooth operation and proper alignment. * **Check and correct alignment:** Ensure that the edge track rollers are properly aligned and that the filter cloth is sitting correctly in the system. * **Inspect and repair the filter cloth:** If the filter cloth is damaged, it might need to be replaced or repaired to ensure effective filtration.
