When dealing with raw water that has very high turbidity, the appropriate adjustment to make is to utilize the Maximum Flocculator Paddle Speed Setting. High turbidity indicates a significant presence of suspended particles in the water, which can hinder the effectiveness of the treatment process.

Using the maximum flocculator paddle speed helps to ensure that these particles are mixed thoroughly with the coagulants added to the water. This vigorous mixing facilitates the collision and aggregation of smaller particles into larger floc that can then be more easily removed during subsequent sedimentation or filtration steps.

By maximizing the paddle speed, the operator can enhance the efficiency of the coagulation and flocculation process, leading to better clarification of the water and improved treatment results. In contrast, using a lower paddle speed would not provide sufficient energy to promote the necessary interactions between particles and coagulants, likely resulting in inadequate treatment of the highly turbid water.
