| description | In this article a new method for the theoretical analysis of electroforced
sedimentation (EFS) by use of the Terzaghi-Voigt combined model is presented.
Zinc oxide and a mixture of zinc oxide and KC-flock are used as experimental
materials. Both the electro-osmotic pressure gradient Epg and the modified consolidation
coefficient Ce of the materials are assumed to be constant. The analytical solution
can explain the solid compressive pressure distribution with time and position. The
progress of electroforced sedeimentation can be represented by an average consolidation
ratio Uc as in mechanical expression. Variations of the effectiveness of EFS with
the percentage of KC-flock in the mixture, electric current density, and total solid
volume per unit cross-sectional area are investigated. EFS is best applied for
materials with permanent charge. |
