Question 4: How do you evaluate and optimize the performance of a clarifier in a water treatment process?

Which action should you take?

Choose only one option

By focusing solely on sedimentation time without optimizing other factors

By using fixed parameters regardless of flow variations

By relying solely on visual inspection to determine performance

By adjusting feedwater flow, coagulant dosages, and detention time based on real-time monitoring

Question 5: When using sulfur dioxide for dechlorination, what must be carefully monitored to avoid under or over-chlorination?

Which action should you take?

Choose only one option

The turbidity of the water before dechlorination

The flow rate of the sulfur dioxide

The amount of chlorine present in the water
