CE 115 Fundamentals of Sedimentation
Education / GUNT Hamburg / Process Engineering / Mechanical Process Engineering /

Sedimentation is often used to clarify suspensions. In the process, the solid particles move downwards in a liquid owing to their density.

  Using CE 115, the sedimentation processes in different suspensions can be investigated and compared. Five transparent cylindrical tanks are provided for the purpose. The suspensions are prepared in measuring cups, poured into the removable tanks, and mixed by shaking. The tanks are then mounted vertically on the experimental unit. To aid observation of the sedimentation process, the tanks are backlit.

Learning Objectives / Experiments

- determination and comparison of the settling velocities of solids in

  suspensions dependent on the solid density and concentration and

  the liquid density and viscosity
- influence of flocculent on the settling velocity
