Mixed Metal Oxide (MMO) Anodes are advanced titanium-based electrodes designed for efficient water purification and wastewater treatment. Their superior durability and electrocatalytic performance ensure high purity and energy efficiency.
Request a QuoteElectrochemical water treatment is a modern, environmentally friendly method for purifying water and wastewater. MMO anodes, typically featuring a Ruthenium-Iridium oxide coating on a titanium substrate, are the core component. They facilitate powerful oxidation reactions, generating strong oxidants like chlorine, hypochlorite, and hydroxyl radicals directly in the water, which effectively destroy organic pollutants, bacteria, and viruses.
Electro-Chlorination: Generating chlorine/hypochlorite for disinfection, especially in seawater or brackish water.
Electro-Oxidation: Direct and indirect oxidation of persistent organic pollutants (POPs) and dyes.
Electro-Coagulation: Used in conjunction with other electrodes to remove suspended solids and heavy metals.
Electrodialysis: Used in desalination and water softening processes.
Low overpotential for oxygen and chlorine evolution reactions significantly reduces the energy consumption of the treatment process.
The robust MMO coating provides a long service life, often exceeding 5 years, even in highly corrosive or harsh water environments.
The titanium substrate is highly resistant to corrosion in acidic and chloride-rich electrolytes, ensuring structural integrity.
Minimizes the need for chemical additives and reduces the formation of harmful disinfection byproducts (DBPs).
We tailor the anode's shape and coating composition to the specific water matrix and treatment goal.
