Fouling by aqueous suspensions of kaolin and magnetite: hydrodynamic and surface phenomena effects

Abstract

When a suspension flows in contact with solid surfaces, the particles it carries can be transported to the walls and, through a process of adhesion form a more or less stable deposit. The basic phenomena of particulate fouling include these two processes, together with the simultaneous removal of the deposited particles. Knowledge of the mechanisms involved and also of their mutual interference is essential to the qualitative as well as quantitative characterization of different fouling situations.
