Difference between flocculated and deflocculated suspension
1. Definition
- Flocculated Suspension: A mixture where fine particles clump together to form larger aggregates (flocs).
- Deflocculated Suspension: A mixture where particles remain separate and do not aggregate, maintaining a uniform dispersion.
2. Settling Behavior
- Flocculated Suspension: Settles quickly due to the larger size of aggregates, making separation easier.
- Deflocculated Suspension: Settles slowly, as individual particles remain dispersed, leading to a more stable mixture.
3. Viscosity
- Flocculated Suspension: Generally has lower viscosity, allowing for easier pouring and mixing.
- Deflocculated Suspension: Typically has higher viscosity, which can make it more challenging to handle.
4. Appearance
- Flocculated Suspension: May appear cloudy, but can clear up once the larger flocs settle.
- Deflocculated Suspension: Often remains consistently milky or opaque due to the uniform distribution of particles.
5. Stability
- Flocculated Suspension: Can be less stable over time; disturbances can break apart flocs and lead to re-dispersion.
- Deflocculated Suspension: Usually more stable, with a lower tendency for settling or separation.
6. Applications
- Flocculated Suspension: Commonly used in water treatment and certain pharmaceuticals where rapid settling is beneficial.
- Deflocculated Suspension: Often found in liquid medications and cosmetics where uniformity and consistency are crucial.
7. Influence of Additives
- Flocculated Suspension: May require flocculating agents to promote aggregation.
- Deflocculated Suspension: Often involves deflocculating agents to maintain particle separation.
