Titanium Anode for Sodium Hypochlorite Generator

Product Introduction

The Titanium Anode for Sodium Hypochlorite Generator is a key component designed for the efficient online production of sodium hypochlorite solution. This generator system is widely used for disinfection and sterilization in municipal water treatment, swimming pools, hospitals, and industrial cleaning processes. The device enables users to produce sodium hypochlorite directly and safely on-site, ensuring continuous and cost-effective operation.

Internal Structure of the Titanium Anode Electrolytic Cell

1. Anode: Titanium substrate coated with Ruthenium–Iridium Mixed Metal Oxide (MMO) for superior electrochemical performance.
2. Cathode: Made from TA1 / TA2 / GR1 / GR2 titanium plates, offering excellent corrosion resistance.
3. Current Density: ≤1500 A/m²
4. Design Life: 3–5 years (customizable according to application requirements)
5. Shell Material: PMMA / UPVC for durability and insulation.
6. Yield: 100 g–1000 g/hour (customizable output capacity)

Working Principle

1. The system works by feeding diluted brine into the electrolytic cell. When DC power is applied through a silicon rectifier, electrolysis occurs, converting saltwater into sodium hypochlorite (NaClO) solution.
2. For each kilogram of sodium hypochlorite produced, salt consumption is about 4.0–4.2 kg, and power consumption is approximately 4.3–4.5 kWh.
3. During electrolysis, hydrogen (H₂) is generated at the cathode and chlorine (Cl₂) at the anode. The hydroxide ions produced combine with sodium ions to form sodium hydroxide (NaOH). The chlorine then reacts with sodium hydroxide to form sodium hypochlorite (NaClO).
4. The electrochemical reaction can be summarized as:​​​​​​​ NaCl → Na⁺ + Cl⁻ → NaClO (Sodium Hypochlorite)

Advantages of Titanium Anode for Sodium Hypochlorite Generator

High Efficiency and Durability:

• Constructed with a 10 mm acrylic shell and 20 mm flange seal, ensuring strong structure, easy maintenance, and superior electrolysis efficiency.

• Produces high-concentration sodium hypochlorite with stable, corrosion-resistant, and long-lasting performance.

Customizable Design:

• The Titanium Anode for Sodium Hypochlorite Generator can be fully customized in size, output, and lifespan to meet different operational requirements.

High-Quality Electrode Manufacturing:

• The core electrolyzer electrode group is independently developed and produced.

• Uses industrial-grade pure titanium substrate with multi-component precious metal oxide coatings to ensure optimal electrochemical activity and extended service life.

In summary, the Titanium Anode for Sodium Hypochlorite Generator provides a stable, efficient, and low-maintenance solution for continuous sodium hypochlorite production, ensuring consistent water disinfection and superior operational reliability.​​​​​​​

Application Advantages

The Titanium Anode for Sodium Hypochlorite Generator is an essential electrochemical component designed for the efficient and stable production of sodium hypochlorite from seawater or brine. Its advanced mixed metal oxide (MMO) coating, typically consisting of ruthenium–iridium oxides (Ru-IrO₂), ensures long-lasting durability and high catalytic performance under harsh electrolysis conditions.

Main Advantages:

• High Electrochemical Efficiency: Ensures stable chlorine and hypochlorite generation with low energy consumption.
• Corrosion Resistance: Excellent resistance to chlorine, seawater, and alkaline environments.
• Long Service Life: Superior coating adhesion provides consistent performance and extended lifespan.
• Low Maintenance: Minimal surface passivation and easy cleaning, reducing downtime.
• Stable Output: Ensures consistent sodium hypochlorite concentration even under variable salinity and temperature conditions.
• Eco-Friendly: Supports on-site sodium hypochlorite production without handling hazardous chlorine gas.

Applications include water treatment plants, marine sanitation systems, swimming pool chlorination, industrial disinfection systems, and municipal water supply projects.

Manufacturing & Process Flow

Each Titanium Anode for Sodium Hypochlorite Generator is produced through a precise multi-stage process to guarantee performance and reliability:

1. Titanium Substrate Selection – High-purity titanium (Grade 1 or Grade 2) is selected for its excellent formability and conductivity.
2. Surface Pretreatment – Degreasing, acid etching, and cleaning to remove oxide layers and ensure coating adhesion.
3. MMO Coating Application – Multiple layers of Ru-IrO₂ or Ti/IrO₂ coating are applied using a thermal decomposition technique.
4. High-Temperature Sintering – Each layer is sintered to achieve strong bonding and stable electrochemical activity.
5. Performance Testing – Coating thickness, adhesion, and electrochemical performance are tested before shipment.

This strict manufacturing control ensures that each anode delivers consistent current efficiency, uniform chlorine release, and long operational stability.
