Worldia’s BDD electrodes are a new type of electrode made from boron-doped diamond (BDD), offering strong application potential in sensors, water treatment, and disinfection. BDD is a premium electrode material widely used in electrochemical advanced oxidation processes (EAOP) for treating organic wastewater. It effectively reduces COD, removes ammonia nitrogen, and lowers overall treatment costs.
EAOP is a highly efficient, eco-friendly, and economical method in which organic pollutants are oxidized into CO₂ and water without generating secondary pollution. With excellent corrosion resistance, BDD electrodes ensure long-term stable operation.
Worldia currently provides BDD electrodes in various specifications, as well as modular units that can be assembled into large electrolytic systems. We offer full-process R&D support—from lab-scale and pilot-scale testing to engineering applications—for high-risk wastewater treatment. These products can be applied in laboratory wastewater and industrial wastewater treatment, disinfection equipment, and more.
Electrochemical advanced oxidation processes
Electrochemical advanced oxidation processes (EAOP) is a highly eficient and environmentally benign technology for organicwastewater treatment.
t operates on the principle of utilizing catalytically active electrode materials to generate hydroxy! radicals, either directly orindirectly, during electrolysis. These radicals effectively degrade organic pollutants, ultimately mineralizing them into carbondioxide and water, This process achieves a very high dearadation rate and avoids secondary pollution.
Boron-doped diamond (BDD) electrodes possess exceptional electrochemical properties derived from the inherent stability ofdiamond's sp3 carbon bonds and the electrical conductivity imparted by boron doping. This combination results in an electrodematerial ideally suited for electrochemical oxidation, Since the oxidation reactions take place at the interface between theelectrode surface and the solution, the anode material is critical for achieving efficient organic pollutant mineralization. Therefore, researching and developing anode materials that are both highly effective and economical has long been a central goal inelectrochemical oxidation research.
Boron-doped diamond electrode has a relatively high oxygen evolution potential and a relatively wide electrochemical window,and is an ideal anode material for electrochemical oxidation treatment of difficult-to-biodegrade organic wastewater.
01High oxygen evolution potential and strong oxidation ability
The electrode reaction produces enhanced hydroxy! radicals, which can effectively degrade organic pollutants;
02Without secondary pollution
The adsorption capacity is weak, and pollutants wil not accumulate on the electrode surface; No external reagents arerequired during the process, which can avoid secondary pollution;
03Exceptional durability with extended service life
BDD electrodes can still maintain good stability and electrode activity under acidic, neutral and alkaline conditions;
04No consumption of electrodes, long service life
Compared with consumable electrodes such as ruthenium, iridium, titanium, and araphite, BDD electrodes have the characteristics of high diamond hardness, strong wear resistance, chemical inertness, and resistance to strong acids and alkalis.
Application
BDD electrodes can be applied to treat various types of organic wastewater, such as those that are high risk, high toxicity, highsalinity, high ammonia nitrogen, intense color, and strong acidity or akalinity. Their use spans many industries, including finechemicals, pharmaceuticals, pesticides, petrochemicals, coking, lithium battery production, eather tanning, electroplating, andwine brewing.
