What types of flocculators are commonly used?

The choice highlighting paddle, turbine, and diffused air as types of flocculators is accurate because these types of equipment are specifically designed to facilitate the flocculation process in water treatment.

Paddle flocculators create a gentle mixing action that is effective for promoting the agglomeration of particles without breaking apart the forming flocs. Turbine flocculators, on the other hand, use a rotating blade to create a more vigorous mixing action, which can help in disperse chemicals that promote floc formation. Diffused air flocculation introduces air bubbles into the suspension, which enhances particle collision rates and can help bring about floc formation efficiently.

Each of these flocculators plays a vital role in various applications of water and wastewater treatment, optimizing the removal of suspended solids from water.
