| description | This paper presents results of experimental work carried out to study and analyze the
combined operation of electro-osmotic dewatering (EOD) and mechanical expression
(ME) by use of the Terzaghi-Voigt combined model for considering creep deformation of
the material. The EOD-ME process combines the advantage of electro-osmosis and
mechanical dewatering, resulting in reduced void ratio compared to individual operation.
The basic differential equation based on the model is solved analytically by assuming that
both an electro-osmotic pressure gradient Epg and a modified consolidation coefficient Ce
of the material are constant, resulting in the equation of solid compressive pressure in the
material as a function of time and position. The analysis also leads to the equation of the
average consolidation ratio Uc, which is a measure of the progress of dewatering; this
equation can describe well the empirical results under various conditions. The large water
content ofbentonite slurry can be reduced well by the EOD-ME combined operation. |
