Anodes for On-Site Hypochlorite Generation

Ru-Ir MMO titanium anodes and electrode assemblies for on-site sodium hypochlorite generation in municipal and industrial water treatment.

Where On-Site Hypochlorite Is Used and How It Works

On-site hypochlorite generation is used for drinking-water disinfection, municipal wastewater and reuse-water disinfection, and biological control in industrial circulating-water systems. Yianteng also supplies titanium anodes and replacement electrode assemblies for prepared-brine hypochlorite generators.

In the electrolytic cell, chloride ions are oxidized at the anode to produce chlorine (2Cl⁻ → Cl₂ + 2e⁻), while water is reduced at the cathode to produce hydrogen and hydroxide ions (2H₂O + 2e⁻ → H₂↑ + 2OH⁻).

Common Challenges

• Unstable chlorine output

• Premature coating degradation

• Scale build-up and rising cell voltage

• Uneven current distribution

• Replacement electrode incompatibility

YIANTENG Solutions

• Active-area sizing based on chlorine output and operating conditions

• Application-specific Ru-Ir MMO coating and loading

• Electrode configurations for polarity-reversing operation

• Replacement electrodes manufactured from drawings, samples or equipment data
