Coated titanium electrodes for Brine Water Electro-Chlorination

For seawater electro-chlorination systems, the Electrolyzer generally divided into concentric Tubular Electrolyzers (CTE) and Parallel Plate Electrolyzer (PPE), the former is for small to medium size seawater system, and the latter is for large capacity system. Both electrolyzers are built up with MMO (mixed metal oxide) coated titanium anodes and titanium cathodes for the sake of Corrosion-resistant, long service life, low energy consumption and easy maintenance characters. 

Fenggang has develop a nano scale multi-layers of mixed metal oxide coating, which includes Ruthenium, Iridium, Platinum, Palladium, Titanium and Tantalum totally six elements. They are proved to increased performance over conventional materials by maximize catalytic phases and surface area interactions. This high density coating technology allows for very thin layers to be deposited increasing cost effectiveness. The Mixed Metal Oxide Coated substrate will undergo multiple thermal treatments at elevated temperatures. This process will achieve very good bonding properties between the mixed metal oxides coating and the substrates. The titanium substrate can be recoated and conductivity and catalytic activity like the new cell anodes.
