Brochure: Diamond Electrode
Modern Wastewater Treatment has never been this Economical and Efficient
Boron-doped diamond electrodes set technological standards in the treatment of wastewater and many other contaminated liquids. Compared to conventional cleaning processes (Advanced Oxidation Processes APO), the Electrochemical Advanced Oxidation Process (EAOP) offers the significant advantage that the use of additional chemicals is unnecessary. Diamond electrodes are corrosion resistant and allow almost 100% current efficiency for the generation of OH radicals in water.
Tribological applications also benefit from our polycrystalline, "real" diamond coating.
The diamond electrode has the largest known overvoltage to generate oxygen and hydrogen. No energy is wasted, but it is almost completely used to generate OH radicals as the strongest known oxidant. The diamond coating is highly corrosion resistant to salts and chemicals in the electrolyte. We rely on polysilicon as the base material for our boron-doped diamond electrodes. This replaces the commercially available niobium substrate and is much more cost-effective and readily available. The mechanical substrate treatment also allows the electrode and cell design to be customized.
When it comes to tribological coatings, DLC (Diamond like Carbon) is usually thought of first, but this wears out much faster compared to our "real" diamond coating. Where conventional mixed friction pairings reach their limits, our "real" diamond coating helps to go the decisive step further.
Diamond-coated electrodes are primarily used in the treatment of wastewater or for recycling process water. Here, this technology reduces the amount of organics in the water. Even thermally and chemically very stable substances, such as hormone or drug residues, are destroyed by oxidation.
In the tribological field, our customers in the mechanical seal and pump industries benefit from our know-how in particularly challenging application environments. For example, when cleanliness requirements do not permit the use of graphite and, in addition, mixed and dry friction occur simultaneously with abrasion. Mechanical seals with diamond-coated seal rings can be found, for example, in mining, the chemical and pharmaceutical industries, and in the oil and gas industry also too.
