Sodium Hypochlorite Generator Anode
Sodium Hypochlorite Generator Anode: Essential Guide for On-Site Disinfectant Production
Sodium hypochlorite generator anodes are specialized electrodes central to systems that convert saltwater or brine into sodium hypochlorite (NaClO) solution via electrolysis, providing a safe, on-site alternative to handling commercial bleach or chlorine gas. These anodes enable efficient disinfectant generation for water treatment and sanitation needs.

Sodium Hypochlorite Generator Anode: Advanced Solutions for Efficient On-Site Disinfectant Production
Ti Time Company emerges as a premier sodium hypochlorite generator anode supplier, leveraging over 15 years of electrochemical expertise to deliver customized MMO-coated titanium electrodes for water treatment and sanitation. In this detailed exploration, we delve into the core attributes of these essential components, highlighting Ti Time’s role in providing solutions that embody proven experience, specialized knowledge, industry authority, and unwavering credibility. From municipal water systems to industrial disinfection, understanding the design, mechanisms, and applications of sodium hypochlorite generator anodes is crucial for achieving safe, sustainable chlorine generation.
The Fundamentals of Sodium Hypochlorite Generator Anodes: Composition and Electrochemical Principles
Sodium hypochlorite generator anodes are the anodic electrodes in electrolysis cells that convert low-concentration brine (NaCl solution, 0.3–0.5% or tap water) into sodium hypochlorite (NaClO) via DC current, offering a safer alternative to storing liquid bleach or handling chlorine gas. The substrate is industrial pure titanium (TA1 or TA2 grades), selected for its mechanical strength (>240 MPa tensile), processability, and passive TiO₂ film that resists corrosion in chloride-rich environments. Coatings consist of mixed metal oxides (MMO, primarily RuO₂ + IrO₂ + proprietary additives), with precious metal content ≥10 g/m², applied via thermal decomposition for uniform adhesion and high catalytic activity.
The electrolysis reaction is: NaCl + H₂O → NaClO + H₂↑. At the anode: 2Cl⁻ – 2e⁻ → Cl₂ (low potential ≤1.13 V, initial ≤1.10 V vs. SCE); at the cathode: 2H⁺ + 2e⁻ → H₂; in solution: 2NaOH + Cl₂ → NaCl + NaClO + H₂O. This process operates at current densities of 1,400–1,500 A/m² (max <5,000 A/m²), with hydrochloric acid <20% and temperatures <80°C for stability. Ti Time’s anodes optimize chlorine evolution, achieving >90% efficiency and 10–20% energy savings over graphite or lead, with guarantees on potential stability during lifespan (5–10 years).
Ti Time’s experience in Baoji’s Titanium Valley enables custom forms—plates, meshes, tubes (e.g., 185 × 44 × 70 mm)—with Ru-Ir coatings for superior selectivity and minimal overpotential.
Key Performance Advantages and Standards
These anodes excel in catalytic activity, acid/alkali resistance, and longevity, with low chlorine potential ensuring high yield and low power use. Compared to traditional anodes, MMO titanium variants avoid sludge, maintain performance in variable humidity/temperature, and offer mechanical durability for complex shapes. Standards like ASTM B265 for titanium and NACE for electrochemical properties guide quality, with Ti Time adhering to ISO 9001 for consistent output.
