DSA Titanium Anode for Sewage Treatment
Titanium mesh with Ir coating Mesh type thickness : 1.5~1.6mm Mesh size:4.5*12.5mm
Product Introduction
Product Description
DSA (Dimensionally Stable Anode) titanium anodes are manufactured using titanium substrates coated with mixed metal oxide (MMO) catalytic layers, such as iridium oxide (IrO₂) and ruthenium oxide (RuO₂).
These anodes provide excellent electrochemical stability, high catalytic activity, and superior corrosion resistance. They are widely used in electrochemical water treatment and heavy metal removal applications, especially in challenging wastewater environments.
Technical Background
DSA titanium anodes are designed to replace traditional consumable electrodes.
Advantages include:
Stable geometric dimensions during operation
High current efficiency
Low energy consumption
Long operational lifetime
The MMO coating enhances electrochemical catalytic performance while protecting the titanium substrate from corrosion.
Case Study: Acid Mine Drainage (AMD) Treatment - Korea
