Scenario:
A water treatment plant uses a DCS system to manage its purification process. The plant has experienced a sudden decrease in water flow rate, impacting the overall treatment efficiency.
Task:
1. Identify two possible causes for this decrease in flow rate based on the information provided in the text.
2. Describe how the DCS system can help identify the specific cause of the problem.
3. Suggest one action the operators could take to address the issue based on the DCS data.
**1. Possible causes:** * **Clogged filtration system:** Impurities might have built up in the filters, restricting water flow. * **Malfunctioning pump:** The pump responsible for transporting water might be experiencing a problem, reducing its efficiency. **2. Identifying the cause:** * **DCS monitoring:** The DCS system can provide real-time data on the flow rate at various points in the treatment process, including before and after the filters and pumps. * **Pressure readings:** The DCS can monitor pressure readings before and after the pump. A significant pressure drop across the pump could indicate a problem. * **Alarm triggers:** The DCS might be configured to trigger alarms if flow rates fall below certain thresholds, indicating an issue. **3. Action:** * **Backwashing filters:** If the data suggests the filters are clogged, operators could initiate a backwash cycle to clean them. This would remove accumulated impurities and restore the flow rate.
