Technologies for ballast water treatment: a review
Journal of Chemical Technology & Biotechnology, 2009 AbstractInvasive aquatic species discharged through ballast water is one of the most serious problems posed nowadays in the marine environment. This review paper summarizes the available technologies applied for ballast water treatment. These technologies can be either port‐based or ship‐based, with the latter being easier to implement.

Hydrogen Peroxide: An Effective Treatment for Ballast Water
The Biological Bulletin, 2001polyphemus size and age. The analysis of cohorts demonstrated that C. fornicata in Pleasant Bay can be divided into 5 size cohorts (Fig. 1A), with C. fornicata of approximately 4–6 mm in length appearing to represent the most recent spatfall. The cohorts differed in abundance, reflecting different magnitudes of recruitment from year to year.

Application of hydrodynamic cavitation in ballast water treatment
Environmental Science and Pollution Research, 2015Ballast 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

Disinfection by-products in ballast water treatment: An evaluation of regulatory data
Water Research, 2012 To reduce the global spread of invasive aquatic species, international regulations will soon require reductions of the number of organisms in ballast water discharged by ships. For this purpose, ballast water treatment systems were developed and approved

Recent Technologies for Ballast Water Treatment
Ozone: Science & Engineering, 2012Concern about ballast-mediated bioinvasions into freshwater, estuarine and marine habitats is not limited to biodiversity per se but extends to its broader socio-economic impacts on agriculture, forests, fisheries, aquaculture, and other human activities dependent on the stability of living resources in a particular ecosystem.

Ballast Water Treatment methods - Systems
2022The present thesis focuses on ballast treatment technologies and how these can be assessed by the buyer in order to select the most appropriate Ballast Water Treatment System (BWTS) for a Bulk Carrier Dry cargo ship. The first Chapter introduce the concept of biodiversity and the need for immediate actions to protect the environment from the invasion ...

Treatment of Ballast Water on Board Ships
2015The global transport of ballast water in ocean-going ships contributes substantially to the spread of aquatic invasive species, with serious consequences to local ecosystems. Therefore, the treatment of ballast water prior to discharge will soon become mandatory. Within the last decade, several dozen ballast water treatment systems have been developed.

Development of an Ultra-Violet Lamp and a Ballast for Ship's Ballast Water Treatment
Journal of the Korean Society of Marine Engineering, 2011Abstract: In this paper, we dealt with the design and fabrication of a medium pressure ultra-violet (UV) lamp and a magnetic ballast which are main components for ballast water treatment systems (BWTS). To acquire an optimal discharge condition of UV lamp, electrical and optical characteristics depending on theargon gas volume and the amount of mercury

Characterization of ballasted flocs in water treatment using microscopy
Water Research, 2016Ballasted flocculation is widely used in the water industry for drinking water, municipal wastewater, storm water and industrial water treatment. This gravity-based physicochemical separation process involves the injection of a ballasting agent, typically microsand, to increase the floc density and size.

Assessing the risk of ballast water treatment to human health
Regulatory Toxicology and Pharmacology, 2012Ballast water management systems utilizing noxious chemicals have to be approved according to the Ballast Water Convention by the International Maritime Organization (IMO). The approval procedure requires human health risk assessment. Our objective was to evaluate the existing human health risk assessment process for ballast water management systems ...
