SEDIMENTATION PHENOMENA

Description

SEDIMENTATION PHENOMENA

This apparatus has been designed for an easy study of the basics of sedimentation process. Five graduated cylinders are mounted vertically on a lighting backboard. Each cylinder may be removed from the board for washing, filling and mixing operations.

• Study of the characteristics and determination of the sedimentation curves of the same suspension with different
concentrations of solids.
• Influence of the density of the solid on the sedimentation velocity.
• Influence of the density and viscosity of the liquid on sedimentation velocity.
• Distribution of particle size. Characteristics of sedimentation of solids of the same density and different particle sizes.
• Study of the variation of the initial height in the sedimentation velocity.
• Study of the use of flocculants. Coagulation-flocculation.
• Comparison of the sedimentation characteristics of different suspensions.
