A flocculated suspension is a suspension in which particles have undergone flocculation.
- Particles exist as loose aggregates.
- Rate of sedimentation is high.
- Sediment formed rapidly.
- Consist of loosely packed particles possessing a Scaffolding structure a hard dense cake does not form and the sedimentation can easily be redispersed.
- Elegant preparation is obtained due to the uniform distribution of loosely bonded flocs.
A deflocculated suspension is a suspension where no flocculation has taken place.
- Particles exist as separate entities.
- Rate of sedimentation is low.
- Sediment formed slowly.
- Sediment becomes very closely packed as the repulsive forces between the particles are overcome a hard cake is formed which is difficult to redisperse.
- Unsightly preparation results due to the formation of sedimentation.
