Titanium Anode for Electrolytic Disinfection
In industrial circulating water, swimming pool water, and domestic water supply systems, microbial control is a critical link in safeguarding water quality safety and equipment operating efficiency. Our Titanium Anode for Electrolytic Disinfection at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for online electrolytic chlorine generation for disinfection. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a ruthenium-iridium mixed metal oxide catalytic coating on the surface. The coating's excellent chlorine evolution activity enables the anode to generate active chlorine efficiently at low cell voltage in water with low chloride ion concentration, achieving rapid inactivation of bacteria, viruses, algae, and other microorganisms. Compared to chemical dosing methods, the electrolytic disinfection approach avoids the risks associated with chemical storage and transportation, and the disinfection concentration can be adjusted by regulating the current, making it a reliable choice for achieving intelligent and refined microbial control in various water treatment systems.

Why Choose Our Titanium Anodes?
- Efficient Chlorine Generation at Low Chloride Ion Concentrations
Chloride ion concentrations in circulating water, swimming pool water, and tap water are typically only tens to hundreds of milligrams per liter, far below industrial brine electrolysis conditions. Our ruthenium-iridium coating is optimized for such chloride-lean water, maintaining high chlorine evolution current efficiency under limited chloride ion availability to ensure the active chlorine concentration required for disinfection is achieved. - Intelligent On-Demand Chlorine Generation
The chlorine output of electrolytic disinfection anodes exhibits a linear relationship with the applied current, enabling precise control of residual chlorine concentration in water through current regulation. This characteristic allows equipment to integrate online residual chlorine monitoring and automatic adjustment systems, achieving refined control of the disinfection process and avoiding the risks of either chemical overdosing or insufficient disinfection. - Eliminating Safety Hazards in Chemical Storage and Handling
Compared to direct dosing of liquid chlorine, sodium hypochlorite solution, chlorine dioxide, or other chemical disinfectants, electrolytic disinfection requires only a small amount of common salt or utilizes the chloride ions already present in the water. This fundamentally eliminates the procurement, transportation, storage, and refilling of hazardous chemicals, reducing safety management burdens and operational risks. - Compact and Flexible Installation Adaptability
We can provide plate-type interdigitated electrode sets, tubular flow-through electrodes, mesh electrodes, and other structural configurations, compatible with bypass electrolytic disinfection modules, pipe-insertion disinfectors, and tank-suspended disinfection units. Small-scale units can be integrated within water purification equipment, while large-scale systems can adopt modular parallel expansion.

The ShenAo Advantage
17 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: Can electrolytic disinfection still be effective when chloride ion concentration in the water is very low?
A: Yes, but the current density and anode area should be reasonably designed based on the chloride ion concentration. Tap water and circulating water typically contain tens of milligrams per liter of chloride ions, which is sufficient for the anode to generate active chlorine. If the chloride ion concentration is too low (e.g., below 20 mg/L), trace salt addition can be considered. You can provide your water quality report, and our engineers will assess whether a salt dosing unit is needed and recommend suitable anode specifications.
Q: What by-products are produced during electrolytic disinfection, and how are they controlled?
A: The main by-products include chlorate and trace amounts of disinfection by-products such as trihalomethanes. By-product generation is related to current density, chloride ion concentration, and hydraulic retention time. Reasonable control of electrolysis intensity and avoiding over-electrolysis are key to reducing by-products. We can assist you in optimizing electrode arrangement and operating parameters to control by-products within safe limits while meeting disinfection requirements.
Q: How should scaling on the anode surface after extended operation be addressed?
A: In water with higher hardness, calcium carbonate or magnesium hydroxide scale may form on the anode surface. Mild scaling can be removed online through periodic polarity reversal operation (swapping anode and cathode polarity), or by dilute hydrochloric acid circulation cleaning. We recommend considering polarity reversal functionality or reserving cleaning connections during the system design phase to reduce maintenance workload.
Q: What scenarios are tubular, plate, and mesh anodes respectively suitable for?
A: Tubular anodes are suitable for pipe-insertion and bypass flow-through disinfection modules, with water flowing between tubes at low pressure drop. Plate anodes are suitable for open tank or water tank suspended installation, offering convenient maintenance and replacement. Mesh anodes feature a high open area ratio, making them suitable for online disinfection units with strict pressure drop requirements. The specific choice can be determined based on your equipment configuration and installation space.
Q: How are finished anodes packaged and shipped?
A: Each anode is individually wrapped in protective packaging to prevent scratching of the coating surface during transit. Bulk orders use custom cushioning boards and sturdy outer cartons to ensure shock and moisture protection during transportation. Export orders can be provided with fumigated wooden crates or air freight-specific packaging upon request.
Safety Notice: This product is intended for integration into electrolytic water disinfection equipment. Equipment manufacturers should ensure end-products comply with relevant local regulations governing water treatment devices, electrical safety, and—where applicable—drinking water disinfection standards and disinfection by-product limits.
