Sedimentation, of suspensions

A number of empirical equations have been obtained for the rate of sedimentation of suspensions, as a result of tests carried out in vertical tubes. For a given solid and liquid, the main factors which affect the process are the height of the suspension, the diameter of the containing vessel, and the volumetric concentration. An attempt at co-ordinating the results obtained under a variety of conditions has been made by Wallis 8 . ... [Pg.240]

Several workers(68,69,70) have studied the sedimentation of suspensions formed of particles of two different sizes, but of the same densities. The large particles have higher settling velocities than the small ones and therefore four zones form, in order, from the top downwards ... [Pg.282]

Several other techniques have been designed to monitor the sedimentation of suspensions, of which photosedimentation, X-ray sedimentation and laser anemometry are worthy of mention. The simplest sedimentation test is based on the visual observation of settling, whereby the turbidity of a suspension is estimated visually, or the height of the sediment and sediment volume are recorded as a function of time. Although this visual estimation of sedimentation is only qualitative, it is adequate for many practical situations. [Pg.404]
