Description

Anti-fouling device for anti-fouling {APPARATUS FOR PREVENTING ADHESION OF BIO FOULING}

The present invention relates to a technique for preventing the adhesion of adherent organisms that occur mainly in marine water.

Bio-Fouling is the accumulation of microorganisms, plants, algae and/or animals on the surface. The diversity of biofouling organisms is very diverse and goes far beyond the attachment of barnacles and seaweed. According to some estimates, more than 1700 species, including more than 4000 organisms, are responsible for biofouling. Biofouling is divided into microfouling, which includes biofilm formation and bacterial adhesion, and macrofouling, which is the attachment of large organisms. Due to the unique chemistry and biology that prevents organisms from sedimentation, these organisms are also classified as hard or soft fouling types. Calcareous (rigid) fouling organisms include barnacles, lichens, mollusks, polychaetes and other tubular and zebra mussels. Examples of non-lime (soft) fouling organisms are seaweed, hydroids, algae and biofilm "mucus". Together, these organisms form a fouling community.

Due to the above-described bio-fouling, the operation of the machine is stopped, the water inlet is blocked, and the ship's hull experiences increased drag. In addition, bio-fouling is attached to sensors for ocean observation, which threatens the accuracy of sensing.

Accordingly, a method for preventing a situation in which bio fouling is attached to various sensors in the ocean is required.

Meanwhile, the above information is only presented as background information to help understanding of the present invention. As to whether or not any of the above is applicable as the prior art related to the present invention, no decision has been made, and no claim is made.
