TRAINING OBJECTIVES
With this equipment, students can perform several experiments:
- Study of the characteristics and determination of sedimentation’s curves of the same suspension with different solids concentrations.
- Influence of the density of a solid in the speed of sedimentation.
- Influence of density and viscosity of the liquid in the speed of sedimentation.
- Particle size distribution. Features of the sedimentation of solids of the same density and sizes of a different particle.
- Study of variation of the initial height in the speed of sedimentation.
- Study of the use of flocculants. Coagulation-flocculation.
- Comparing characteristics of sedimentation of different suspensions.
TECHNICAL DESCRIPTION
The system consists of 5 glass tubes placed in a graduated support with a backlit panel structure.
it is possible to see through this system, the sedimentation process and its intermediate steps, so that the sedimentation speed can be measured.
The trainer is supplied with 5 beakers of 250 ml and a 2-liter jug where suspensions can be prepared and then they can be poured into the tubes.
Tubes can be extracted from their site to be able to agitate them until obtaining a homogenous dissolution of the aggregated solids.
