Mechanism of agglomeration and sinking
Last Updated March 29, 2024
Mechanism of agglomeration and sinking
- Suspended matter (turbid components) in raw water are usually in a state where they rebound from each other and are dispersed.
- Here, when a coagulant is injected, the coagulant sticks to the surface of the turbid component, eliminating the repulsion of the turbid component, and the turbid component becomes a lump. In addition, stirring and lumps collide and grow into large lumps (flocks).
- Large-grown flocks become heavier and easier to sink.
State of the coagulation sedimentation experiment
①It's cloudy. I'll put the coagulant here.
②After mixing with the coagulant, the turbid components stick to the muddy components, and a lump (flock) is formed.
③The clump (flock) becomes larger, heavier and sinks.
