Almost any surface, whether living or inert, when brought into contact with a fluid will become fouled. Hence, the effects of surface fouling are extremely widespread, with fouling occurring, for example, on heat transfer surfaces, the hulls of ships and marine structures, medical prostheses, plant surfaces, animal tissues, filtration, membranes etc. The type, or combination of types, of fouling that occur on a particular surface varies. For example, in the case of heat transfer surfaces, the type of fouling can be divided into six main categories (1): viz: particulate or sedimentation fouling, precipitation fouling or scaling, corrosion fouling, reaction fouling, freezing or solidification fouling and biological fouling (biofouling). We shall concentrate on the phenomenon of biofouling. |
