Scenario: You are working at a water treatment plant responsible for providing clean drinking water to a community. The plant uses a reverse osmosis (RO) system to remove impurities from the water. Your conductivity sensor readings are showing a gradual increase in the conductivity of the treated water over the past few weeks.
Task:
**1. Possible Reasons for Increased Conductivity:** * **RO membrane fouling:** The RO membrane may be accumulating contaminants, reducing its effectiveness in removing dissolved impurities. * **Leak in the RO system:** A leak could introduce untreated water with higher conductivity into the treated water stream. * **Change in source water quality:** The raw water source might have experienced an increase in dissolved impurities, leading to a higher conductivity in the treated water. **2. Potential Consequences:** * **Reduced water quality:** The treated water may not meet drinking water standards, potentially posing health risks to the community. * **Increased operational costs:** The RO system might require more energy or chemicals to maintain the desired water quality. * **Reduced RO system lifespan:** Membrane fouling can shorten the lifespan of the RO membrane, leading to costly replacements. **3. Actions to Investigate and Address:** * **Inspect the RO membrane:** Visually inspect the membrane for any signs of fouling or damage. * **Test the RO system for leaks:** Check for leaks in the piping and connections throughout the RO system. * **Analyze the raw water source:** Monitor the conductivity of the raw water source to identify any changes in quality. * **Consider cleaning or replacing the RO membrane:** If fouling is identified, cleaning or replacing the membrane may be necessary to restore its performance. * **Adjust the operating parameters of the RO system:** Fine-tuning the RO system's operating pressure, flow rate, or other parameters might improve its effectiveness.
