The electrodes are usually constructed from the highly corrosion-resistant material titanium, and the anode is coated with ruthenium oxide or iridium generally.
Disinfection system using this chloride system can effectively reduce the corrosion rate of the swimming pool equipment and the swimsuit bleaching injury, not only because of the use of soft water but also can greatly reduce the stimulation to the skin.
In many cases, projects for sewage treatment use this kind of anode to reduce costs, but because of Environment requirements, the Titanium Anode of the Pb02 coating has been used less than before.
