LogEasy Exercise:
Scenario: A water treatment plant is using LogEasy to monitor the effectiveness of their filtration system. The plant manager observes a sudden increase in particle counts in the treated water.
Task: Using your understanding of LogEasy and particle counting, suggest three possible reasons for this increase and describe how LogEasy could help investigate each reason.
Exercice Correction
Here are three possible reasons and how LogEasy could help investigate them:
- **Filter Failure:** The filter itself may be failing to remove particles effectively. LogEasy can help by:
- Providing real-time particle counts to track the change in particle concentration as it passes through the filter.
- Analyzing particle size distributions to identify if there is a specific size range of particles that are not being removed.
- **Increased Influent Load:** The raw water entering the treatment plant may have a higher particle load than usual. LogEasy can help by:
- Monitoring particle counts in the raw water to compare it to the treated water and determine if there is a significant difference.
- Analyzing the size distribution in both raw and treated water to see if the same particle sizes are being found in both.
- **Operational Error:** There may be an error in the operation of the treatment plant, such as a malfunctioning pump or a change in flow rate. LogEasy can help by:
- Tracking particle counts over time to identify any sudden changes that coincide with potential operational errors.
- Using the data logging and reporting features of LogEasy to identify any trends or patterns that may point to an operational issue.
