“…It can be clearly seen from the table 2 that, rate of disinfection is increased by almost 2 times compared to that of only chlorination when it is combined with hydrodynamic cavitation. Less amount of sodium hypochlorite requirement will also result into less formation of disinfection by products which are harmful to the environment and which need to be disposed of safely [35,36] after the disinfection treatment. The per pass disinfection is also an important parameter as it tells us the number of passes through the cavitating device needed to achieve log 4 reduction.…”

“…Clay minerals are clay-sized (< 2µm) fraction of soils [40]. Most of the sediments that accumulate in ballast tanks are in clay and silt size (<63 µm) [13], [25]. As a result, the particle size to be selected had to be below 63 μm when scaled up to real size.…”

“…If a ship has been installed with a ballast water treatment system which makes use of active substances, the sediment may play role as a repository for disinfection byproducts. This in turn increases the human exposure risk during several occasions such as the ballast water sampling, tank maintaining (sediment cleaning) and tank inspection [25]. The sediments also may be an important sink for heavy metals and compounds that are originated from the deterioration of tank plates used for the structural members and tank coating residues [13], [26], [27] which brings about potential ecological risks.…”

SummaryBallast tank sediments may cause several problems in a wide range changing from environmental to economical. Its contribution to biological invasion is an important concern. Thus, the sediment management is included as an integral component of the "The International Convention on the Control and Management of Ships' Ballast Water and Sediments". The reduction of the amount of the sediment to be removed is of great importance for management issues. Therefore, the convention underlines that ships should be designed and constructed with a view to minimize the uptake and undesirable entrapment of sediments and facilitate removal of sediments. Design and construction solutions can effectively be developed after determination of the problem areas. In this study, sediment accumulation pattern and problem areas in the ballast tank model of a longitudinally framed double bottom tanker is determined. The problem areas are found to be at the mid-section of the tank closer to the centre girder.

“…Nevertheless, ships transporting ballast water has been recognized as a major pathway for the spread of aquatic organisms into new habitats (Stehouwer et al 2015). It is estimated that annually about 10 billion tons of ballast water are transferred globally, and more than 3000 species are transported by ships each day (Banerji et al 2012). To prevent the introduction of potentially invasive species, regulations for the control and management of ballast water was drafted and ratified by the International Maritime Organization (IMO) in February 2004.…”

The ability of a 2-stage (filtration + UV/Ag-TiO 2 /O 3) ballast water treatment process to control non-indigenous species introduction has been assessed. The removal efficiencies of turbidity and phytoplankton were monitored during the filtration pretreatment phase, and the degradation of phytoplankton (Dunaliella salina and Phacodactylum tricornutum) chlorophyll a (chl-a) by UV/Ag-TiO 2 /O 3 were investigated. Results showed that 50 μm screen filtration could remove a small part of phytoplankton, and reduce the turbidity. Compared to individual unit processes with ozone or UV/Ag-TiO 2 , the removal of chl-a by the combined UV/Ag-TiO 2 /O 3 process was enhanced, and the effluent exhibited a persistence toxicity within 24 h. The results indicate that a combination of filtration and UV/Ag-TiO 2 /O 3 advanced oxidation maybe a promising method for ballast water treatment.
