MMO Titanium Electrode Assembly For Sodium Hypochlorite Generator

A sodium hypochlorite generator is a device in which the salt water of low concentration is electrolyzed by electrodes, the electrochemical reaction happens and it generates sodium hypochlorite finally. Here gives an example of an electrolytic cell and MMO anode.

The detailed technical data of the anode for sodium hypochlorite production:

  • Lifespan: 3 years,5 years, and 10 years according to the client’s requests and demands.
  • Solution: 5% sodium chloride solution.  
  • Current density: 800-1500 A/m2.
  • Temperature: less than 60 degrees.
  • Production amount requested: 1.25kg/hour.  

Chlorine evolution efficiency of the electrolytic tank, over 90% in a salt solution, and over 85% in seawater (the Sodium chloride concentration should be 3 %-5% in seawater.)

Chlorine evolution potential: less than 1.13V.

Polarizability of potential difference: less than 40 mV (test the potential difference under the current density of 200 A/M2 and 2000A/M2.)

Available chlorine is 8-10g/l in the sodium hypochlorite solution produced.

Details of Accelerated life testing regarding 5-year request:

  1. Solution: 0.5 molar/L, H₂SO₄.
  2. Temperature: 40±1 degree
  3. Current density: 20000A/M2
  4. Qualified after 50 hours’ test, which shows MMO anodes for sodium hypochlorite production reaches the 5-year lifespan.
