Scenario: You are designing an I&C system for a new wastewater treatment plant. The plant will have a primary clarifier, aeration tanks, and a final clarifier.
Task:
Example:
Parameter: Flow rate in the primary clarifier Sensor: Magnetic flow meter Control: The I&C system will monitor the flow rate and adjust the inlet valve to maintain a consistent flow rate, preventing overloading of the clarifier.
Exercise Correction:
Here's a possible solution, keep in mind this is a simplified example, real-world systems are more complex:
Primary Clarifier:
| Parameter | Sensor | Control | |---|---|---| | Flow Rate | Magnetic flow meter | Adjust inlet valve to maintain a consistent flow | | Influent Suspended Solids | Turbidity sensor | Alert operator if suspended solids levels exceed a set limit | | Sludge Level | Ultrasonic level sensor | Activate sludge withdrawal system when level reaches a set point | | pH | pH sensor | Adjust chemical feed for pH adjustment | | Temperature | Temperature sensor | Monitor and alert if temperature exceeds a certain limit |
Aeration Tanks:
| Parameter | Sensor | Control | |---|---|---| | Dissolved Oxygen (DO) | Dissolved oxygen probe | Adjust aeration system to maintain desired DO levels | | pH | pH sensor | Adjust chemical feed for pH adjustment | | Mixed Liquor Suspended Solids (MLSS) | Turbidity sensor | Control sludge return rate based on MLSS levels | | Flow Rate | Magnetic flow meter | Maintain consistent flow rate through the aeration tanks | | Temperature | Temperature sensor | Monitor and alert if temperature exceeds a certain limit |
Final Clarifier:
| Parameter | Sensor | Control | |---|---|---| | Flow Rate | Magnetic flow meter | Monitor and alert if flow rate deviates significantly | | Effluent Suspended Solids | Turbidity sensor | Alert operator if effluent turbidity exceeds a set limit | | Sludge Level | Ultrasonic level sensor | Activate sludge withdrawal system when level reaches a set point | | pH | pH sensor | Monitor pH and alert if it falls outside a certain range | | Temperature | Temperature sensor | Monitor and alert if temperature exceeds a certain limit |
Note: This is just a sample solution, the actual I&C system design would depend on the specific requirements of the wastewater treatment plant and local regulations.
