What is the recommended frequency for turbidity monitoring in water treatment facilities?

The recommended frequency for turbidity monitoring in water treatment facilities is every 15 minutes because this interval strikes a balance between ensuring accurate and responsive monitoring while allowing for effective data management. Turbidity is a critical indicator of water quality, reflecting the presence of suspended particles that can impact treatment processes and public health. Monitoring it too frequently, such as every 5 or 10 minutes, may lead to unnecessary strain on resources and personnel without significantly enhancing the responsiveness to changes in water quality. On the other hand, monitoring every hour may not be responsive enough to detect rapid changes that could affect treatment efficiency and safety. Therefore, every 15 minutes provides a suitable compromise, allowing operators to quickly identify and address any issues related to turbidity.
