Aqua-View Exercise:
Scenario: A water treatment plant is experiencing issues with filter clogging. The plant manager suspects the presence of high levels of suspended particles in the incoming water.
Task:
- Explain how the Aqua-View system can be used to diagnose the filter clogging problem.
- What specific data points would the plant manager need to analyze from the Aqua-View system to confirm their suspicion?
- Suggest possible solutions to the filter clogging issue based on the Aqua-View data.
Exercice Correction
1. **Diagnosis:** The Aqua-View system can be installed at the plant's intake point to monitor incoming water quality in real-time. By analyzing particle counts and size distribution data, the plant manager can determine if high levels of suspended particles are indeed present. 2. **Data Points:** The plant manager should look for: * **High particle counts:** A significantly higher than normal particle count indicates excessive particulate matter in the water. * **Dominant particle sizes:** Identifying the sizes of particles that are most prevalent will help determine the type of filters needed (e.g., coarse or fine) to effectively remove them. 3. **Possible Solutions:** * **Pre-filtration:** Installing a pre-filtration system before the main filters can help remove larger particles, reducing the load on the main filters. * **Filter Optimization:** Adjusting the filter media type or changing the filter cleaning schedule based on the identified particle sizes can enhance filtering efficiency. * **Source Identification:** If the Aqua-View data reveals persistent high particle levels, investigating the source of contamination and addressing it at the source could be necessary.
