CE 115 Fundamentals of sedimentation
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.
