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.

Ship ballast water ultrasonic treatment
The Journal of the Acoustical Society of America, 2002Ballast water is treated by applying ultrasonic frequencies to the water to kill organisms entrained in the water such as diatoms, veligers, fish larvae, plankton, and microorganisms, preventing the introduction of non-indigenous species between ports-of-call. The ballast water is circulated through a ballast treatment system.

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

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.

Technologies for ballast water treatment: a review
Journal of Chemical Technology & Biotechnology, 2009AbstractInvasive 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.

Heating techniques in ballast water treatment
2013Ballast water is recognized as a vector for transference of various species from one geographical region to others, all around the world. Consequences are influence on ecology of species in the environment where ballast water is discharged, with the possible impact on human health and/or economy.

Ballast Water Treatment Technologies and Shipboard Demonstrations
OCEANS 2006 - Asia Pacific, 2006Ballast water has been largely responsible for the global transfer of harmful aquatic organisms. When discharged into a new environment, some aquatic plants and animals carried in ballast water may become invaders and seriously disrupt the native ecology and economy.

Effective Ship Ballast Water Treatment System Management
2013Shipping runs the major part of world trade. Using ballast water is the most common way to stabilize a ship after loading and unloading the cargo. Taking ballast water after unloading the cargo would increase the ship’s weight. Therefore draught of the ship increases to the level before unloading.
