Electrolytic chlorination to produce hypochlorite had adopted carbon and platinum as electrode material, but they are proven inefficient, cumbersome and costly. DSA titanium electrode is a simple, reliable and cost efficient solution according to experiment. Below is a test report of over potential and corrosion data for anode materials used in the electrolysis of sodium chloride.
Parameters of Titanium Electrodes for Seawater Electro Chlorination:Substrate Material:

AUE has developed series of Nano-scale multi-layer 6 elements mixed metal oxides coating, they includes Ruthenium, Iridium, Platinum, Titanium, Tantalum; Palladium. This coating improves the efficiency and performance over conventional ruthenium oxide coating by maximize electro catalytic activity and interactions of coating surface area. The electrode substrate material is Gr1 titanium, which provides excellent stability and corrosion prevention performance.
Features:
Multiple titanium anode /cathode plates;
Bi-polar & mono-polar plate designs;
Electrode replacement every 5 – 10 years depending on use and Salt & Water Quality.
Applications:
Power station seawater electrolysis;
Power plant biofouling control.
Bleach production plant.
Chlor-alkali industry
The salt cell in a salt chlorinator is the part that actually converts Salt (NaCl) to Chlorine, which consists of a plastic housing and the electrodes. TheTitanium electrode sheet for salt chlorine generator usually constructed from the highly corrosion resistant material titanium, and the anode is coated with ruthenium oxide or iridium generally. The composition of this coating plays a major role in both the chlorine producing efficiency of the cell and its life expectancy.
Parallel Plate Electrolyzer, known as Plate Electrolyzer or PPE Electrolyzer, it is constructed of bipolar electrode stack. This Parallel Plate Electrode (PPE) system is the optimum solution for large capacity seawater cooling systems. Large capacity is provided by cell modules assembled together and coupled with bus bars to a power rectifier, forming a sodium hypochlorite generating train.
