Bentonite clay improves coagulation by which mechanism?

Explanation:
The main idea is that coagulation relies on forming flocs and then letting them settle. Bentonite clay acts as ballast, adding mass and density to the forming flocs so they sink more quickly under gravity. This heavier floc improves clarification without significantly changing pH or altering particle charges. It’s not about alkalinity, pH changes, or stabilizing charges—the benefit comes from the added weight that enhances settling.
