The precious metal coating on titanium anode has low resistivity, good conductivity (compared to the poor conductivity of titanium itself), and stable chemical composition. In addition, it is also resistant to corrosion and has a long working life span. Our Dimension Stable Anode (DSA) is used in a variety of fields. For example, our DSA is used in the treatment of industrial waste water. Through the oxidation reaction on the surface of DSA, organic material can be efficiently eradicated, therefore achieving a purifying effect. DSA can be also used in sea water desalination technology, which can convert sea water, whose salinity reaches 60g /L, to potable fresh water. This technology has the great potential to solve the drinking water problems in desert areas.
