Titanium Anode for Acid-Alkaline Ion Water Generator
In the operation of acid-alkaline ion water generators, anode performance directly influences electrolysis efficiency and product water quality. Our Titanium Anode for Acid-Alkaline Ion Water Generator at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for continuous or batch electrolytic ion water equipment. It uses Grade 1 or Grade 2 pure titanium as the substrate, with a noble metal oxide catalytic coating on the surface. This anode maintains stable electrolytic activity even in low-concentration electrolyte solutions, operating reliably in the membrane-separated electrolysis environment between cathode and anode chambers. Whether used for generating alkaline drinking ion water, acidic disinfectant water, or electrolytic functional water for industrial cleaning, it provides your equipment with a stable, clean, and long-lasting electrode solution.

Why Choose Our Titanium Anodes?
- Stable Electrolytic Activity and Output Water Quality
The coating maintains low oxygen and chlorine evolution overpotentials even in low-conductivity water, ensuring efficient and stable electrolysis. Over long-term operation, the coating consumption rate is very low, with minimal metal ion dissolution, safeguarding the purity of the product water at its source. For equipment requiring consistent output of functional water with stable pH and oxidation-reduction potential, this stability forms the foundation for process consistency. - Adaptability to Low-Concentration Electrolysis Conditions
Ion water generators typically use tap water without additional salt dosing or with only trace electrolyte addition, resulting in conductivity far lower than industrial electrolytes. Our coating formulation is optimized for such lean electrolyte conditions, maintaining good electrochemical reaction efficiency at limited ion concentrations and avoiding cell voltage rise caused by concentration polarization. - Clean and Safe Material System
The coating employs a noble metal oxide system validated through long-term use, remaining chemically stable within the normal electrolysis potential window. The titanium substrate offers excellent resistance to aqueous corrosion. The entire electrode introduces no heavy metals or other harmful leachables during use, making it suitable for applications involving food contact and high hygiene requirements. - Compatibility with Various Equipment Structures
We can supply anodes in flat plate, perforated mesh, woven mesh, and other configurations, compatible with mainstream continuous-flow electrolysis cells and batch-type ion water generator designs. Whether your equipment uses a vertical filter-press layout or a horizontal multi-cell series configuration, electrode solutions with matching dimensions and connections are available.

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: What type of coating is typically used for titanium anodes in ion water generators?
A: It depends on the type of water the equipment produces. For equipment primarily producing alkaline drinking water, iridium-based coatings with good oxygen evolution activity are typically used on the anode side, maintaining stability under tap water electrolysis conditions. For equipment that also produces acidic disinfectant water, ruthenium-iridium coatings can be selected, leveraging their chlorine evolution activity to generate an appropriate amount of active chlorine on the anode side. We recommend providing your equipment design parameters and water quality report for evaluation.
Q: What factors most significantly affect anode service life?
A: Key factors include: feed water hardness (calcium and magnesium ion content), electrolysis intensity, operating duration, and electrode polarity reversal frequency. Water with higher hardness tends to form scale on the anode surface, increasing cell voltage. It is recommended to install softening and pretreatment units before the water inlet. Regular electrode polarity reversal or acid cleaning maintenance can also help extend service life.
Q: Is it normal for the anode surface to turn yellow or discolored after long-term use?
A: The titanium substrate naturally forms a very thin oxide film in the water electrolysis environment, appearing pale yellow or light brown. This is a normal passivation phenomenon of titanium and does not affect the electrode's conductivity or catalytic activity. However, if the color darkens significantly to deep brown or patchy flaking appears, an inspection is recommended.
Q: Can the anode be made in circular or other custom shapes?
A: Yes. We can customize circular, annular, arc-shaped, and other non-standard anode plates according to your electrolysis cell dimensions and internal layout. Simply provide your drawings or key dimensions, and we will evaluate the processing plan and provide samples for confirmation.
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 foam lining 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.
