Specifications of Titanium Anodes for Seawater Electrolysis Disinfection | Technical Analysis from Titanium Anode Manufacturers for Seawater Electrolysis Disinfection

With the rapid development of marine engineering, mariculture, and seawater cooling systems, seawater electrolysis disinfection technology plays a crucial role in preventing marine organism attachment, pipe scaling, and bacterial growth. In seawater electrolysis disinfection systems, the titanium anode is a key electrode material, its performance directly affecting electrolysis efficiency, system stability, and equipment lifespan.

I. Working Principle of Titanium Anodes for Seawater Electrolysis Disinfection
Seawater electrolysis disinfection systems typically utilize naturally occurring chloride ions in seawater. Under direct current, an electrochemical reaction occurs, generating chlorine gas and hypochlorous acid, achieving sterilization, disinfection, and inhibition of marine organism attachment.

The anode reaction is: 2Cl⁻ → Cl₂ + 2e⁻. The generated chlorine gas reacts with water to form hypochlorous acid (HOCl), which has strong bactericidal capabilities, effectively controlling the attachment of bacteria, algae, and shellfish in seawater systems.

Seawater environments are characterized by high salinity and high corrosiveness. Ordinary metal anodes cannot be used for extended periods. Insoluble titanium anodes with an MMO coating can operate stably in high-chlorine environments.

II. Structure of Titanium Anode Material for Seawater Electrolysis Disinfection
The titanium anode for seawater electrolysis disinfection consists of the following two parts:
1. Titanium Substrate
The titanium anode substrate for seawater electrolysis disinfection uses industrial-grade TA1 or TA2 titanium, characterized by:
* Excellent resistance to seawater corrosion
* Stable electrical conductivity
* High mechanical strength
* Resistant to deformation during long-term operation

The titanium substrate acts as a conductive framework during electrolysis and does not participate in the electrochemical reaction.

2. MMO Noble Metal Oxide Coating
The surface of the titanium anode for seawater electrolysis disinfection is coated with an MMO noble metal oxide coating, which is a ruthenium-iridium system and includes:
* Improved chlorine evolution efficiency
* Reduced electrolysis voltage
* Enhanced corrosion resistance
* Extended electrode lifespan

A stable coating is formed through multiple coating processes and high-temperature sintering, ensuring that the titanium anode for seawater electrolysis disinfection maintains good electrocatalytic performance during long-term operation.
