What is the term for reducing turbulence in flocculation basins by gradually decreasing mixer speed?

The term for reducing turbulence in flocculation basins by gradually decreasing mixer speed is referred to as "tapered energy mixing." This method involves adjusting the energy input to the mixing process in a manner that allows for the formation of flocs without causing excessive shear or turbulence, which could break apart newly formed particles.

In the context of water treatment, tapered energy mixing is essential for optimizing floc formation and ensuring effective settling of particles within the basin. By gradually reducing the speed of mixers, operators can lead to a controlled environment where larger, more cohesive floc structures can develop, enhancing the efficiency of the flocculation process.

Other options may describe related processes but do not specifically capture the concept of gradually decreasing mixer speed to manage turbulence effectively.
