A biofouling suppression device is disposed at a stage before the reverse osmosis membrane element to suppress biofouling that occurs on the surface of the reverse osmosis membrane.

The anti-fouling casing comprises a hydrophobic surface the serves to prevent biofouling of the surface.

The hydrophobic streamer skin/casing may reduce the drag of the streamer and may provide anti-biofouling properties to the streamer.

The invention provides a process of removing or preventing biofouling, particularly on surfaces of industrial and agricultural equipment in contact with aqueous liquids.

The disinfection and biofouling control systems provide suitable treatment while reducing the potential for corrosion of ship components and, in some cases, undesirable disinfection byproducts.

The multilayered coating when applied to a metal component utilized in a marine environment provides for corrosion and/or bio-fouling resistance.
