- Traitement des eaux usées : Surveillance du pH, de l’oxygène dissous, de la conductivité et du potentiel redox pour optimiser les processus de traitement biologique et le rejet des effluents.
- Traitement de l’eau industrielle : Surveillance de divers paramètres dans les tours de refroidissement, les chaudières et autres processus industriels pour prévenir la corrosion, l’entartrage et le colmatage.
- Surveillance environnementale : Mesure des paramètres de qualité de l’eau dans les rivières, les lacs et autres plans d’eau pour évaluer leur santé et suivre les niveaux de pollution.

CLAM Exercise:
Scenario:
You are working at a water treatment plant. The CLAM monitoring the incoming water supply shows a sudden spike in turbidity.
Task:
- Identify the possible causes of the increased turbidity.
- Explain what actions should be taken to address the issue and ensure the safety of the water supply.
- Describe how the CLAM can help in monitoring the effectiveness of the corrective actions taken.
Exercice Correction
**Possible Causes:** * Increased rainfall or runoff leading to sediment entering the water source. * Equipment malfunction or failure (e.g., filter blockage, pump failure). * Accidental release of contaminants into the water supply. **Actions to Take:** * **Investigate the cause of the turbidity spike:** Review plant operations, weather patterns, and recent events. * **Increase filtration and treatment processes:** Adjust the filtration system to remove the suspended particles. * **Monitor water quality closely:** Continuously monitor the turbidity level and other relevant parameters using the CLAM. * **Alert relevant authorities:** If the cause is unknown or poses a significant risk, inform regulatory agencies and public health officials. **Role of CLAM:** * The CLAM provides continuous real-time monitoring of the turbidity level. This allows for immediate detection of changes and quick action to address the issue. * It can also track the effectiveness of the corrective actions taken by monitoring the turbidity levels over time. If the turbidity levels decline after the implemented measures, it confirms the effectiveness of the actions. * The CLAM data can be used to identify trends and patterns in water quality, helping to prevent future turbidity issues.
