“…formed by the •OH chain reaction in ballast water; 3) HOBr/OBr − formed by the reaction between •OH and Br − of the sea; and 4) bromoamine compounds (NH 2 Br, NHBr 2 , NBr 3 ) formed by the reactions between HOBr and ammonia/amines. Meanwhile, because of the certain potential environmental toxicity of residual TROs, the treated ballast water must be neutralized by Na 2 S 2 O 3 before discharge when the residual TROs concentration ≥0.2 mg/L [88]. Furthermore, there was no hazardous effect on local algae, invertebrates, or fish from the treated ballast water in an eco-toxicity evaluation [88].…”

Plasma gas injection as one of the non-thermal plasma (NTP) technologies has a free-standing gas-phase plasma reactor outside the polluted target and can efficiently degrade contaminants by injecting plasma gas containing a large number of reactive species. This approach has been utilized in various fields of pollutants treatment, because of its structural advantage of indirect contact between pollutants and electrodes and its ability to produce strong oxidizing species. This article first expounds on the principle of the plasma gas injection and then progresses to a discussion of its application for pollutants degradation, mainly focusing on the treatment effect and degradation mechanisms. It is believed that plasma gas injection is considered to be a very practical, clean, efficient, and environmentally friendly method for pollution control.

“…Successful tests of UV and EC treatment systems have been evaluated previously, but always as one system per paper. [30][31][32][33][34] Of these studies, only Sutherland et al [30] address regrowth. This is the first time that multiple systems using multiple treatment types were directly compared.…”

The spread of aquatic invasive species through ballast water is a major ecological and economical threat. Because of this, the International Maritime Organization (IMO) set limits to the concentrations of organisms allowed in ballast water. To meet these limits, ballast water treatment systems (BWTSs) were developed. The main techniques used for ballast water treatment are ultraviolet (UV) radiation and electrochlorination (EC). In this study, phytoplankton regrowth after treatment was followed for six BWTSs. Natural plankton communities were treated and incubated for 20 days. Growth, photosystem II efficiency and species composition were followed. The three UV systems all showed similar patterns of decrease in phytoplankton concentrations followed by regrowth. The two EC and the chlorine dioxide systems showed comparable results. However, UV- and chlorine-based treatment systems showed significantly different responses. Overall, all BWTSs reduced phytoplankton concentrations to below the IMO limits, which represents a reduced risk of aquatic invasions through ballast water.

“…The treatment methods of ballast water mainly include UV treatment [2], electrolyzing seawater [3,4], hydroxyl radicals technique [5,6], ozone oxidizine [7], thermal treatment. Although some methods have obtained approval of IMO, the application is restricted by many factors, such as second etching, cost and treatment efficiency.…”

A UV ballast water treatment system was built in this paper. Nitzschiaclosteriumminutissima, Dunaliellasalina and Escherichia coli were selected as the test organisms to run the tests. The test results show that the inactivation ratio for the Escherichia colican close to 100%, when using 5UV lamps and the circulation volume was 5m3/h. While the inactivation ratio for the Nitzschiaclosteriumminutissima and Dunaliellasalina were 86.67% and 82.10%respectively. The investigation provides a better understanding of the UV ballast water treatment further.
