The low bacterial abundances in our running seawater aquaria may, therefore, have been caused by Biofouling (the colonisation of an interface by a diverse array of organisms) is almost always a problem where it occurs, as it negatively affects surfaces, the materials that they are made from and the structures that they form, and can even destroy them. This comprehensive book covers in detail in its first section the processes …. Show all. Biofouling refers to the accumulation of microorganisms on exposed marine surfaces.

Biofouling, or biological fouling, is the accumulation of microorganisms, plants, algae, or small animals on wet surfaces that have a mechanical function, causing structural or other functional deficiencies. There are two phases or types of biofouling: microfouling and macrofouling. Biofouling is a particular problem for underwater structures, such as pipelines, cables, fishing nets, and bridge pillars.

Unchecked, it causes significant operational problems such as frequent interruption, damage to the membranes, intense chemical and energy use, and regular cleaning-in-place (CIP) of the RO. How to minimize the effects of biofouling The introduction of invasive aquatic species (IAS) as a result from international shipping has been identified as a significant threat to the world’s oceans and coastal ecosystems and research suggests that 70-80% of IAS introductions occur through biofouling. Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or animals on wetted surfaces. Such accumulation is referred to as epibiosis when the host surface is another organism and the relationship is not parasitic. Nevertheless, ecological and economic research on freshwater biofoulers has been limited.
