Fouling is the settlement, and sometimes the growth, of undesired materials on solid surfaces in a way that reduces the efﬁciency of the affected part. Fouling may be caused by either the operating environment or by one of the equipment’s processes. It deteriorates protective coatings on the metals and reduces corrosion resistance as well as physical and mechanical properties of the material. Fouling is a common phenomenon that occurs in a wide range of equipment and enviroments and can be caused by living organisms or by non-living deposits.
Fouling can be classiﬁed into two broad categories: microfouling and macrofouling.
Macrofouling is caused by coarse matter of either inorganic or biological origin, such as animals and plants. An example is what occurs in heat transfer components in heat exchangers - the course matter may be contained in the polluted cooling waters or contaminated gases from the wind. This fouling can cause blockages or fretting damage. Microfouling is caused by bacteria and unicellular algae (slime). Composite fouling is caused by more than one fouling mechanism or foulant. Growing depends on the number of sunny days and sea temperatures Marine fouling is a typical composite fouling and occurs due to seaweed, bacteria and other living organisms in the waters, which adhere to immersed surfaces such as ship hulls. The organisms settle on the surface and grow quickly, forming a layer that covers the surface, attracting and trapping more material. We all know, the growing hull of the vessel and its underwater elements cause a lot of problems in navigation.
Ultrasound is mainly used in industry, medicine, for cleaning purposes… Our device works on the principle of converting electrical energy into mechanical energy through a transducer. The transducer transmits ultrasonic vibrations that resonate through the hull, ruder, propeller… of the boat and thus prevents the formation of bioﬁlm. Ultrasonic vibrations also create cavitation effect below the water surface. Cavitation effect destroys the cells of microorganisms and stops them from adhering to the underwater part on the hull. Microorganisms and bioﬁlm are food for algae and seashells that adhere to the hull and underwater parts of a boat, such as rudder, propeller… Ultrasonic antifouling is environmentally friendly.
Smart Modular 2-6 allows us, to select any number of transducers that can be controlled via one control unit. Easy to upgrade the system. Up to ... X Transducers (see the technology) The processor in the Main Box enables us to control each transducer separately in terms of power, frequency and operating time. First of all, it is necessary to ﬁnd out on which part of the hull is the greatest growing. Propellers, rudders, hulls ... Most attention should be paid to the drive, the rudder blade and, of course, the hull.
