Сonducting inland and sea research of purifying and disinfecting of water ballast, expanding the scope of maritime industrial boundaries with the involvement of highly qualified partners from Turkey, as well as at the global level of the maritime industry. popup.description2 As part of state-funded research work, DINUOMA scientists developed an innovative laboratory installation for ballast water treatment and designed a comprehensive solution for a multifunctional ballast water management system for large-capacity marine vessels. The system was developed with scalability in mind, which was implemented through modeling an installation with a base capacity of 250 m³. This required creating detailed 3D drawings and conducting thorough analysis of water treatment components - ozone, sodium hypochlorite, and hydrogen. A significant achievement was the possibility of technology simplification through redundancy of core modules - UV reactors, ozone generators, and chloride dosing units. Considerable attention was paid to process automation. The developed control scheme design provides automatic water flow control, treatment mode regulation, and monitoring of key parameters - pressure and temperature. Comparative analysis of mass and dimensional characteristics revealed that ultraviolet systems, despite their compactness, require more energy compared to electrolysis systems. To optimize UV reactor operation, a model was developed to correlate their power output with water transparency index (UV-T), implementing a correction coefficient KUV-T. The study of existing ballast water treatment systems, particularly technologies from leading manufacturers Wärtsilä and Alfa Laval, revealed the need for modernization of installations in Ukrainian ports. In response, an innovative technology for ballast tank treatment was developed, combining ozone treatment of water-diluted slurry with subsequent application of concentrated sodium hypochlorite. The project concluded with the creation of a scalable economic model that considers vessel water displacement and enables forecasting costs for procurement, installation, and operation of ballast water treatment systems.
