The entry of aquatic invasive organisms into nonlocal waters through ballast water is a serious challenge for the entire maritime industry. TJNE ballast water treatment technology provides reliable treatment solutions for new and modified ships, which can comply with the strictest ballast water regulations in the world. The titanium electrode for seawater electrolysis plays a crucial role in the process of treating ballast water, which is essential for preventing the spread of harmful aquatic organisms and pathogens across different marine environments. In ballast water treatment systems, this electrode facilitates the electrolysis process, where an electrical current is applied to seawater, resulting in the generation of chlorine and other reactive species. These compounds are highly effective at disinfecting the water by killing or inactivating a wide range of microorganisms, including bacteria, viruses, and invasive species that could disrupt local ecosystems.
The exceptional corrosion resistance and durability of titanium ensure that the electrode maintains its performance over time, providing reliable operation in demanding conditions. Furthermore, titanium electrodes for seawater electrolysis can support high current densities, which enhances the efficiency of the electrolysis process, leading to quicker and more effective treatment of ballast water.

Working Principle
Titanium electrode for seawater electrolysis utilizes electrochemical reactions to effectively treat ballast water. It generates chlorine and other oxidizing chemicals, which have strong disinfection properties, when an electric current is applied. These chemicals actively kill or remove harmful bacteria, microorganisms, and other pathogens present in the ballast water, ensuring the ballast water is clean and safe before discharge.
Structure
Titanium electrode for seawater electrolysis is specifically designed for use in ballast water treatment systems on marine vessels. Made of grade 1 titanium, it provides excellent corrosion resistance in seawater environments. The electrode consists of two main components - the titanium substrate and the mixed metal oxide coating.
The titanium substrate has a mesh-like structure that maximizes surface area. It is made by sintering high-purity titanium powder into a porous network. The high surface area allows for efficient electrochemical reactions during electrolysis of seawater. The mesh structure also allows for low flow resistance as water passes through the electrode.
On top of the titanium substrate, a thin coating of mixed metal oxide is applied using thermal decomposition. This coating is a proprietary blend optimized for chlorine generation. It typically contains oxides of ruthenium, iridium, tin, and other electrocatalysts. The coating significantly lowers overpotential and improves activation kinetics for the electrolytic reactions, resulting in efficient chlorine generation at low voltages.
