The article deals with the problem of preventing the transfer of invasive marine organisms with ballast waters of ships into various sea and river areas and the issues of equipping ships of a mixed navigation area with efficient shipboard ballast water treatment systems based on their performance parameters and overall parameters, safety for crew members and ship structures in accordance with the requirements of the International Convention for the Control and Management of Ship’s Ballast Water and Sediments. The study analyzed the standards of the International Convention for the Control and Management of Ballast Water and Sediments of 2017, regulating the replacement and quality of ballast water during operation and construction of sea and river vessels D-1 and D-2. In accordance with the rules of the Convention, the main methods and methods of treatment of seawater are presented by means of physical, mechanical and chemical effects, in order to determine the effectiveness of the impact of these methods on invasive organisms contained in ballast waters. The current technologies of physical and chemical disinfection of ballast with chlorine and ultraviolet radiation in modern developments are presented; their effectiveness is evaluated when used together with the method of mechanical filtration. The analysis of the technical characteristics of the modern development of shipboard ballast processing systems approved by the International Maritime Organization, determining their performance criteria has been made. The results of this study is to determine the most relevant methods for processing shipboard ballast used in modern seawater treatment systems onboard a ship, the ranges of allowable processing equipment capacity in accordance with the limited weight and dimensions required for the possible installation of cleaning equipment on ships of a mixed navigation area in accordance with the requirements and the rules of the International Convention for the Control and Management of Ship’s Ballast Water and Sediments. The study presented the main criteria for the selection of ballast treatment systems for river-sea vessels sailing.
