Biofouling is a naturally-occurring process that takes place whenever a structure is immersed in seawater. Wet equipment can quickly become impacted by almost unavoidable fouling and, as a result, biofouling affects almost every sector of the marine industry. biofouling, some scientists (Drake & Lodge, 2007) regard biofouling as presenting a higher risk of species introduction than ballast water. However, predominance of invasive species vectors appears to differ for different regions (Gollasch, et al., 2010).

The settlement and colonization of marine organisms on submerged man-made surfaces is a major economic problem for many marine industries. The most apparent detrimental effects of biofouling are increased fuel consumption of ships, clogging of membranes and heat exchangers, disabled underwater senso …

The reverse osmosis used in this technology face many potential problems, namely scale and deposits, biofouling, physical stresses and chemical damage. efficient operation, and lack of control in one step significantly impacts on the next.

Before a problem can be solved, it must first be defined. Biofouling is simply the attachment of an organism or organisms to a surface in contact with water for a period of time. That explanation sounds fairly straightforward, but there are several organisms that cause biofouling, many different types of surfaces affected by it, and, due to the

The variety among biofouling organisms is highly diverse and extends far beyond attachment of barnacles and seaweeds. According to some estimates, over 1700 species comprising over 4000 organisms are responsible for biofouling. [1] Biofouling is divided into microfouling — biofilm formation and bacterial adhesion — and macrofouling — attachment of larger organisms. University of Auckland bioengineers have developed an innovative way to get rid of the underwater biofouling that creates such a headache for marinas, boaties and aqua farmers. Electroclear, a new spin-out company based at Auckland Bioengineering Institute (ABI), is using electric fields to disrupt small organisms’ ability to live on selected underwater surfaces.

Ship hull in-water cleaning and its effects on fouling-control coatings for marine organisms to attach and proliferate, a problem commonly known as biofouling.

Biofouling is also considered one of the main vectors for bioinvasions and is described as the undesirable accumulation of microorganisms, plants, algae and animals on submerged structures (especially ships’ hulls). Studies have shown that biofouling can be a significant vector for the transfer of invasive aquatic species. This adhesion called biofouling causes great environmental damage and makes ships use 40% more fuel to travel the same distance. This phenomenon that affects ships and other marine vessels has an important environmental cost and an annual economic cost of more than five million dollars as it increases the fuel consumption of ships.
