“…UV light is known to impair DNA and cellular structures, thus compromising the viability of treated organisms (Holzinger and Lütz 2006). Advantages of UV and its derivatives treatments such as advanced oxidation processes (Wu et al 2011;Rubio et al 2013a, b) include the absence of chemicals and low formation of disinfection by-products (Jorquera et al 2002;Mamlook et al 2008;Werschkun et al 2012;Fisher et al 2014;Zhang et al 2014;Gonsior et al 2015). On the other hand, the inactivating effect of UV is limited by the lack of residual effect and the existence of cellular mechanisms to minimize the damage caused by the treatment, primarily based on DNA photorepair under photosynthetically active radiation (Fafanđel et al 2002;Oliveri et al 2014;Poepping et al 2014).…”

Ultraviolet disinfection is a frequent option for eliminating viable organisms in ballast water to fulfill international and national regulations. The objective of this work is to evaluate the reduction of microalgae able to reproduce after UV irradiation, based on their growth features. A monoculture of microalgae Tisochrysis lutea was irradiated with different ultraviolet doses (UV-C 254 nm) by a flow-through reactor. A replicate of each treated sample was held in the dark for 5 days simulating a treatment during the ballasting; another replicate was incubated directly under the light, corresponding to the treatment application during de-ballasting. Periodic measurements of cell density were taken in order to obtain the corresponding growth curves. Irradiated samples depicted a regrowth following a logistic curve in concordance with the applied UV dose. By modeling these curves, it is possible to obtain the initial concentration of organisms able to reproduce for each applied UV dose, thus obtaining the dose-survival profiles, needed to determine the disinfection kinetics. These dose-survival profiles enable detection of a synergic effect between the ultraviolet irradiation and a subsequent dark period; in this sense, the UV dose applied during the ballasting operation and subsequent dark storage exerts a strong influence on microalgae survival. The proposed methodology, based on growth modeling, established a framework for comparing the UV disinfection by different devices and technologies on target organisms. This procedure may also assist the understanding of the evolution of treated organisms in more complex assemblages such as those that exist in natural ballast water.

“…Several authors have reported the use of advanced oxidation processes such as microwave irradiation, UV radiation, fenton oxidation for ballast water treatment [10][11][12][13]. Although these techniques are effective in removing the seawater microorganisms, the major problems are associated with the scale up and maintenance of such processes on board a ship.…”

“…An example of such technology is the UV irradiation, alone or in combination with some mechanical treatment (Veldhuis et al 2010;Gregg et al 2009). However, as it is mentioned in previous chapter, the effectiveness of UV irradiation could sometimes be limited (Gregg et al 2009;Minchin 2006;Veldhuis et al 2010;Wu et al 2011a;Wu et al 2011bZhang et al 2014. With the aim of achieving better effectiveness, UV is often combined with different advanced oxidation processes (AOPs), such as titanium dioxide (TiO 2 ), ozone (O 3 ), the combination of silver, ozonation and TiO 2 photocatalysis (Ag-TiO 2 +O 3 ), hydrogen peroxide (H 2 O 2 ) (Agustina et al2005;Zhang et al 2014;Wu et al 2011a;Wu et al 2011b).…”

Ballast water is, together with hull fouling and aquaculture, considered the most important factor of the worldwide transfer of invasive non-indigenous organisms in aquatic ecosystems and the most important factor in European Union. With the aim of preventing and halting the spread of the transfer of invasive organisms in aquatic ecosystems and also in accordance with IMO's International Convention for the Control and Management of Ships Ballast Water and Sediments, the systems for ballast water treatment, whose work includes, e.g. chemical treatment, ozonation and filtration, are used. Although hydrodynamic cavitation (HC) is used in many different areas, such as science and engineering, implied acoustics, biomedicine, botany, chemistry and hydraulics, the application of HC in ballast water treatment area remains insufficiently researched. This paper presents the first literature review that studies lab- and large-scale setups for ballast water treatment together with the type-approved systems currently available on the market that use HC as a step in their operation. This paper deals with the possible advantages and disadvantages of such systems, as well as their influence on the crew and marine environment. It also analyses perspectives on the further development and application of HC in ballast water treatment.
