Which step uses a high molecular weight material to attract or trap particulates, getting them to settle?

Explanation:
Flocculation is the step that uses high molecular weight polymers to bridge and trap small particles, forming larger aggregates (flocs) that settle more easily under gravity. After coagulation destabilizes particles, these long-chain molecules connect multiple particles, creating flocs that can settle in a sedimentation basin. Disinfectants target microbes, not particle aggregation. Sedimentation is the gravity-driven settling of already formed flocs, not the bridging action itself.
