Abstract
When a piece of cloth is introduced into an agitated suspension of fine particles, interaction between the surface forces on the particles and on the cloth material occurs and results in simultaneous removal-redeposition and agglomeration-dispersion proc esses. The mechanical aspect of these processes was studied here using Kaolin clay particles, standard AHLMA cloth, and de-ionized water. In order to monitor the changes of the suspension state, particle counts were made with the Coulter Counter. Observed similarities between the agglomeration-dispersion process and the depo sition-removat process lend support to the assumption that forces of the same nature are responsible for both. Consequently, the agglomeration properties of other particu late soil suspensions are expected to be ultimately related to their soiling characteristics. 1 Minerals and Chemicals Corp. of America. 20 Essex Turnpike, Menlo Park, N.
