Hydrodynamic Aspects of Flocculation,his assumption the only permitted interactions are those of the external force fields resulting from combined attraction and repulsion. According to the far-reaching DLVO theory, the field forces are a consequence of London-van der Waals attraction and electrical double layer repulsion..

Preface,The separation of finely-divided solids from liquids constitutes an important stage in many industrial processes. Separation of mixtures ranging from highly concentrated slurries to slightly turbid liquids must be effected in circumstances where the solids, liquid or both phases may have value.

Blocking Filtration. Application to Non-Newtonian Fluids,Blocking filtration laws have been first studied by Hermans and Brédee [1]. Gonsalves [2] made a critical study of the physical models used to derive these laws. Grace [3] made a thorough analysis of the blocking laws in relation with the performance of the filter media to be used, with particular reference to the Standard blocking law.

Centrifugal Separation,The basis of this separation process is formed by Darcy’s equation for the flow of fluids through particulate material:

Dewatering by Compression,On an overall basis about 20% of the combustion energy used by French industry is used in operations for eliminating water. This nas led to a considerable development in techniques for dehydrating at low energetic cost.
