Titanium Electrolytic Cell for Sodium Hypochlorite Generator

​​​​​​​Titanium Electrolytic Cell for Sodium Hypochlorite Generator

In on-site sodium hypochlorite generation equipment, the electrolytic cell serves as the core reaction unit, with its design rationality and material durability directly determining the available chlorine output, energy consumption level, and long-term operational reliability of the equipment. Our Titanium Electrolytic Cell for Sodium Hypochlorite Generator at Baoji City ShenAo Metal Materials Co., Ltd. is designed specifically for the dilute brine electrolysis chlorine generation process. It uses Grade 1 or Grade 2 pure titanium for the cell body and electrode substrates, with a ruthenium-iridium mixed metal oxide catalytic coating on the anode surface. The electrolytic cell features an optimized electrode spacing and flow channel design, enabling uniform distribution of dilute brine between electrodes and efficient active chlorine generation at the anode while maintaining low cell voltage. The complete electrolytic cell maintains stable electrochemical performance and structural integrity in chlorine-containing brine environments, minimizing the risk of metal ion dissolution, and is suitable for various commercial and industrial-grade sodium hypochlorite generation equipment.

Technical Specifications

Why Choose Our Titanium Anodes?

• Optimized Electrode Spacing and Flow Channel Design
  The interior of the electrolytic cell features a proven electrode spacing and flow channel layout, enabling uniform distribution of dilute brine across the electrode surfaces. This design helps reduce concentration polarization effects, maintain stable cell voltage, and allows the active chlorine generated at the anode to exit the electrode surface quickly with the water flow, reducing side reaction losses and improving the current efficiency of available chlorine output.
• High Chlorine Evolution Activity of the Ruthenium-Iridium Coating
  The anode uses a ruthenium-iridium mixed metal oxide coating with a very low chlorine evolution overpotential in dilute brine systems. Compared to graphite or stainless steel electrodes, this significantly reduces cell voltage at the same current density, thereby lowering equipment operating power consumption. The introduction of the iridium component also enhances the coating's durability in the oxygen evolution side reaction environment, extending the electrolytic cell maintenance interval.
• Long-Term Reliability of the All-Titanium Structure in Brine Environments
  Both the cell body and electrode substrates are fabricated from pure titanium, providing excellent corrosion resistance in chlorine-containing brine environments. The naturally formed passive film on the titanium surface remains stable under normal electrolysis conditions, minimizing the dissolution of metal ions into the generated sodium hypochlorite solution and contributing to consistent disinfectant solution quality.
• Modular Design for Easy Maintenance and Capacity Expansion
  The electrolytic cell can adopt a monopolar or multi-polar modular design, allowing equipment manufacturers to flexibly configure the number of electrode sets according to different chlorine output requirements. The electrode assembly of an individual module can be independently removed for cleaning or replacement, reducing the operational difficulty and time cost of routine maintenance.

Real-World Applications

• Water Treatment and Disinfection: Used as the core electrolysis unit of sodium hypochlorite generators in drinking water disinfection, wastewater treatment, swimming pool disinfection, and other water treatment fields, producing active chlorine disinfectant on-site.
• Chlor-Alkali and Halogen Chemical Production: Used in small-scale chlor-alkali and sodium hypochlorite production units, producing sodium hypochlorite solution or chlorine gas through brine electrolysis, suitable for industrial-grade disinfectant preparation.
• Industrial Wastewater Treatment: Used in electrolytic oxidation units of industrial wastewater treatment systems for cyanide-containing, phenol-containing, and other wastewater types, achieving pollutant degradation through anodic chlorine generation or direct oxidation.
• Hydrometallurgy and Metal Recovery: Used in hydrometallurgical process stages requiring in-situ active chlorine generation, such as chlorination leaching of gold-bearing ores and other auxiliary treatment processes.

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: How do I select the appropriate electrolytic cell specification based on target chlorine output?
A: Available chlorine output is directly related to electrolysis current and anode area. According to Faraday's law, the theoretical chlorine output per ampere-hour is approximately 1.3 grams. You can provide your equipment's target chlorine output, and our engineers will calculate the required total electrode area based on this, and determine the electrode quantity and arrangement for the electrolytic cell in combination with the recommended current density range.

Q: What type of brine is suitable for the electrolytic cell?
A: We recommend using 3%–5% dilute brine prepared from food-grade or refined salt. The brine should be fully dissolved and filtered to remove insoluble impurities. The calcium and magnesium ion content in the brine should be controlled as much as possible, as higher hardness brine tends to form scale on the cathode surface, affecting electrolysis efficiency. We recommend installing a water softening pre-treatment unit at the inlet.

Q: What causes white deposits on the electrode surface after extended operation?
A: White deposits are primarily calcium-magnesium carbonate or hydroxide scale, originating from hardness components in the salt or preparation water that have not been adequately removed. Mild scaling can be removed through periodic polarity reversal operation or dilute acid circulation cleaning. For areas with high water hardness, we recommend enhanced brine softening and pre-treatment measures.

Q: Can the electrolytic cell be customized with non-standard dimensions and special connections?
A: Yes. We can customize the external dimensions, inlet and outlet connection specifications, and electrical connection methods of the electrolytic cell according to your equipment design. Whether it is a micro electrolytic cell integrated into a compact cabinet-type device, or a large electrolytic cell assembly for high-flow industrial-grade generators, all can be designed to your requirements.
