Abstract

See full text

The invention provides a simple, inexpensive, accurate, and rapid method of measuring particle settling velocity comprising: (i) providing a gravity settler such as a column; (ii) filling the column with a first homogenous particle suspension, wherein the particle concentration in the first homogenous particle suspension is X, (iii) separating the column into an upper sub-column and a lower sub-column with a height h after settling the first homogenous particle suspension for a period of time t, wherein some particles remain in the upper sub-column; (iv) removing the particle suspension in the upper sub-column and mixing the particle suspension confined in the lower sub-column with a height h to prepare a second homogenous particle suspension; (v) measuring the particle concentration in the second homogenous particle suspension X; and (vi) determining the particle settling velocity v with the formula: v=h(X−X)ltX. Also provided are device and system for carrying out the method.
