The use of boron doped diamond electrodes opens completely new applications in waste water treatment because the direct production of oxidizers with high potential such as hydroxyl radicals (OH-radicals) is possible. No other electrode material guarantees this production.
Diamond is a non-conductor. Only when the diamond is doped with boron, conductivity exists and the diamond is suitable for the electrolysis of water. There are some other materials such as tin or lead with comparable properties, however, when they are used as electrolysis electrode, they emit contaminants (heavy metals) into the electrolyte to be treated such as pool water. With the boron doped diamond the contamination effect can be avoided. The pro aqua diamond electrode has been developed for special applications such as pool water disinfection, disinfection in food industry, drinking water disinfection where no contamination is allowed. These durable and long-lasting diamond electrodes cannot emit contaminants (heavy metals) even under high stress because they do not contain any.
