In What Industries Are MMO Coated Titanium Strip Anodes Mainly Used?
Mixed Metal Oxide (MMO) coated titanium strip anodes, particularly those featuring ruthenium and iridium coatings, are indispensable in various industrial applications due to their exceptional electrochemical properties. These anodes offer high conductivity, corrosion resistance, and durability, making them suitable for harsh environments.

What Are the Primary Applications of Ruthenium Iridium Coated Titanium Anodes in Water Treatment?
Ruthenium iridium coated titanium anodes play a pivotal role in water treatment applications, leveraging their unique properties to address various water quality issues. These anodes are increasingly important due to global water scarcity and the need for efficient treatment technologies.

Electrochlorination Systems
One of the primary applications is in electrochlorination systems, where these anodes facilitate the on-site generation of chlorine for water disinfection. By electrolyzing saltwater or brine solutions, the anodes produce chlorine efficiently, eliminating the need for transporting and storing hazardous chlorine gas. Their high catalytic activity allows for effective chlorine production even at low salt concentrations, making them suitable for both seawater and freshwater applications.

Electrodialysis Desalination
In electrodialysis desalination, ruthenium iridium coated titanium anodes provide stable potential and current density, withstanding corrosion under extreme acid, alkali, and salinity conditions. This ensures a long service life and stable performance, improving desalination efficiency and reducing operating costs.

Wastewater Treatment
These anodes are effective in wastewater treatment applications, promoting the electrochemical oxidation of organic pollutants. Their excellent electrochemical properties, including high current efficiency and low overpotential, make them highly efficient in removing pollutants from wastewater. Additionally, they produce no harmful by-products, making them a safer and more sustainable option.

How Do MMO Coated Titanium Anodes Enhance Cathodic Protection Systems?
Cathodic protection is a technique used to prevent corrosion of metal structures by making them the cathode of an electrochemical cell. MMO coated titanium anodes, particularly those with ruthenium and iridium coatings, are integral to impressed current cathodic protection (ICCP) systems.

Marine and Offshore Structures
In marine environments, these anodes protect structures like ship hulls, offshore platforms, and pipelines from corrosion. Their robustness and ability to withstand aggressive corrosive processes make them ideal for such applications.

Underground Pipelines and Reinforced Concrete
For underground pipelines and reinforced concrete buildings, MMO coated titanium anodes provide long-term stability and durability. Their excellent mechanical strength and corrosion resistance ensure the longevity and safety of these structures.

What Role Do Ruthenium Coated Titanium Electrodes Play in Electrochemical Processes?
