Settling Rates and Sediment Volumes of Flocculated Kaolin Suspensions

Applications of the phenomenological theory to several published experimental cases of sedimentation processes

“…The last condition ensures that batch settling processes of ideal suspensions, for which σ e ≡ 0 is assumed, terminate within finite time. However, in practice and for flocculated suspensions for which σ e , does not vanish, empirical approaches such as Michael and Bolger's [16] generalization…”

Chemo-physical evolution and microstructure features of lime treated soils

“…A multi-scale investigation on the sedimentation behaviour of clay suspensions under different pore water chemistry has been developed highlighting the chemo-physical mechanisms controlling particle arrangement and the soil fabric formation. Sedimentation behaviour of clay suspension is closely related to the electrochemical interactions acting at particle level [18][19][20][21][22][23][24]. Changes in the pore water chemistry induced by addition of lime affect the extent of attraction and repulsion forces among particles, controlling the microstructural features of the sediment formed from suspensions.…”

Sedimentation of Magnetic Suspensions of Magnetite

“…Michaels and Bolger [4] analysed the sedimentation of flocculated suspensions by replacing the solid concentration in eq. 2 by an effective volume fraction , which represents particle aggregates and entrapped fluid in the interstitial space.…”

“…The more complex the particle shape, the higher the value of (> 1). Turian et al [5] used the following expression to represent the sedimentation of narrow-sized coal suspensions: U /U t = (1-k ) 4.68 and found that the value of k varies between 1.15 to 1.2 for different narrow size fractions. Sedimentation of binary and polydisperse concentrated suspensions were studied by a number of authors [6][7][8][9][10][11][12][13] using colloid and noncolloid particles.…”
