Anode for Electrolytic Wastewater Treatment
In the electrolytic treatment of industrial wastewater, the electrocatalytic activity and durability of the anode determine pollutant degradation efficiency and system operating costs. Our Anode for Electrolytic Wastewater Treatment at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for the electrochemical oxidation treatment of various types of industrial wastewater. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a noble metal oxide catalytic coating on the surface. In complex wastewater systems containing chlorides, organics, or high salinity, the coating maintains stable electrocatalytic activity, achieving efficient degradation of organic pollutants through strong oxidizing species such as active chlorine and hydroxyl radicals generated at the anode surface. The anode maintains a stable chemical state during operation, minimizing the risk of metal ion dissolution and avoiding secondary contamination of the treated effluent, making it a reliable electrode solution for industrial wastewater electrochemical treatment processes.
This product is for B2B Industrial Use Only. Operators should follow relevant chemical safety protocols and wastewater treatment operation standards.

Product Advantages
- Coating Formulation Design for Different Wastewater Types
Different industrial wastewaters vary significantly in pollutant composition and electrolyte conditions, each placing distinct demands on the anode coating. Chloride-containing wastewater emphasizes chlorine evolution activity for efficient active chlorine generation, while phenol-containing or high-COD organic wastewater emphasizes oxygen evolution activity for hydroxyl radical generation. Our coating formulation can be optimized based on your wastewater type and water quality parameters, achieving a favorable balance between pollutant-specific degradation efficiency and long-term coating stability. - Chemical Stability in Complex Wastewater Environments
Industrial wastewater often contains acids, alkalis, salts, and various organic and inorganic pollutants, exerting continuous chemical attack on electrode materials. Our coating formulation is optimized to maintain a low corrosion rate and good structural integrity in wastewater with wide pH fluctuations, high salinity, and complex compositions, making it suitable for long-term continuous wastewater treatment processes. - Open Structure to Prevent Clogging and Scaling
Mesh and perforated plate anodes feature a high open area ratio, resisting clogging when treating wastewater containing suspended solids or prone to scaling, allowing water to flow smoothly across the electrode surface. This open structure also facilitates the rapid dissipation of gases generated during electrolysis, preventing cell voltage rise and effective reaction area reduction caused by gas accumulation. - Flexible Modular Expansion
We can provide single or multiple anode modules in series-parallel combinations based on your treatment capacity and pollutant concentration. Whether for low-flow precision treatment or high-flow rapid treatment, processing capacity can be flexibly adjusted by adding or removing modules, accommodating wastewater treatment needs of varying scales.

The ShenAo Advantage
18 A long time of Fabricating Excellence
Since 2008, we've specialized in valuable metal coated titanium anodes from our office in Baoji's "China Titanium Valley." Our develop bimetallic hazardous welding innovation and progressed coating forms provide items you can trust.
Customization for Your Correct Needs
Every generation line is diverse. We give custom fitted arrangements coordinating your particular current thickness necessities, electrolyte composition, and operational parameters. Whether you require little bunch testing or full-scale generation amounts, we convey on time.
Cost-Effective Lifecycle Management
When coating exhaustion happens, you do not dispose of the whole anode. Our proficient recoating benefit strips the ancient oxide layer, sandblasts the substrate, and reapplies new MMO coating. This expands resource life and decreases your add up to taken a toll of proprietorship considerably.
Frequently Asked Questions
Q: How do I select the appropriate anode coating based on wastewater type?
A: It primarily depends on the main pollutants and electrolyte composition in the wastewater. Wastewater with higher chloride ion content (such as electroplating rinse water and certain chemical wastewaters) is suitable for ruthenium-iridium coatings, utilizing the chlorine evolution reaction to generate active chlorine for indirect oxidation. Organic wastewater containing phenols, dyes, or high COD but with low chloride ion content is suitable for iridium-tantalum coatings, generating hydroxyl radicals through the oxygen evolution reaction for direct oxidation. You can provide your wastewater quality report, and our engineers will recommend a matched coating solution.
Q: What should be noted when treating wastewater containing suspended solids with anodes?
A: For wastewater containing suspended solids, mesh or perforated plate anodes are recommended, utilizing their high open area ratio to reduce clogging. It is also advisable to install a pretreatment unit (such as sedimentation or filtration) at the inlet to control suspended solid particle size and concentration. During operation, periodically inspect the anode surface for solid deposit accumulation and arrange online or offline cleaning as needed.
Q: What factors are related to the anode consumption rate?
A: The consumption rate is primarily related to the pH value, chloride ion concentration, fluoride ion content, operating current density, and temperature of the wastewater. Strongly acidic or fluoride-containing wastewater will accelerate coating consumption. We recommend providing a detailed wastewater composition analysis during the selection stage so we can assess coating compatibility and provide a service life estimate.
Q: How should anodes be handled when the coating reaches the end of its service life?
A: The titanium substrate remains stable in wastewater environments. The old coating can be chemically stripped, and once the substrate passes inspection, it can be recoated to restore performance to new-anode levels. We offer a full-service process including incoming inspection of used anodes, coating stripping, substrate treatment, and recoating.
