Why Choose Boron-Doped Diamond(BDD) Electrode Electrolysis Treatment for Hazardous Waste
About Boron Doped Diamond Electrode Electrolysis
BDD Electrolysis and Boron-Doped Diamond BDD Electrode
Boron doped diamond electrode electrolysis, it involves electrochemical oxidation process, an electrochemical reaction that employs a Boron-Doped Diamond (BDD) electrode as the anode (BDD anode), possesses considerable importance. To fully grasp the intricacies of BDD electrolysis technology, it is necessary to thoroughly understand the complexities associated with BDD electrodes.
When diamond is doped with boron, its physicochemical properties undergo significant changes. Research indicates that boron doping enhances the electrical conductivity of diamond and reduces the resistivity of diamond film to a range of 0.01~100 Ω-cm. This facilitates swift electron migration during electrochemical reactions. Boron-doped diamond (BDD) exhibits a wide electrochemical window, high electrooxidation capability, low background current, and excellent chemical stability, making it an ideal electrode material.
Boromond utilizes its proprietary chemical vapor deposition (CVD) equipment to coat substrates with boron-doped diamond (BDD) films. This process involves the use of boron and carbon gases as the primary raw materials, which are subjected to high-temperature dissociation within a low-pressure furnace. The resulting carbon and boron atoms are then deposited onto the substrate surface, enabling efficient mass production of BDD coatings.

Advanced Oxidation Processes for Wastewater Treatment
After we understand BDD electrode, the following part is to introduce Electrochemical Advanced Oxidation Process technology, BDD anodes can throughly degrade refractory organic pollutants. Find out how boron doped diamond accomplish efficient water remediations through electrochemical advanced oxidation processes,
Introduced in 1970, electrochemical oxidation technology has gained significant attention in wastewater treatment and disinfection due to its environmentally friendly and efficient characteristics. When coupled with flocculation, biochemistry, membrane treatment, and other technologies, it offers remarkable advantages and promising prospects for the deep purification and treatment of highly concentrated refractory wastewater.
Utilizing boron-doped diamond as the electrode anode material, electrochemical oxidation technology can effectively degrade organic compounds through direct and indirect oxidation processes. Direct oxidation involves the removal of organic matter by adsorbing organic pollutants onto the anode surface through electron transfer. This process can further be categorized into electrochemical conversion and electrochemical combustion based on the degree of oxidation. Indirect oxidation, on the other hand, involves the removal of organic pollutants by generating active intermediates or high oxidizing metal oxides on the anode surface.
Boromond leverages electrode modules based on BDD electrode material as the core, enabling the continuous degradation of organic pollutants under normal temperature and pressure conditions. This process eliminates the need for chemical additives, relying solely on electricity consumption with minimal material usage. The simplicity and efficiency of this approach offer significant advantages. Boromond has developed test modules, trial modules, and integrated wastewater treatment modules to scale up electrochemical oxidation wastewater treatment to an industrial level. These sustainable and highly efficient electrochemical treatment equipment solutions contribute to effective and environmentally-friendly wastewater management.
OH radicals are recognized as one of the most potent oxidants in existence.
Water, being a polar molecule, exhibits a positive and negative end. During the process of water electrolysis, the positively charged hydrogen atoms are attracted to the negatively charged electrode (cathode), while the negatively charged oxygen atom is drawn towards the positively charged electrode (anode). As a result, the water molecules dissociate into their respective ions: hydrogen ions (H+) at the cathode and hydroxide ions (OH-) at the anode.
The water electrolysis process can be summarized by the following half-reactions:
At the cathode: 2H+ + 2e- -> H2 (hydrogen gas)
At the anode: O2 + 2H2O + 4e- -> 4OH- (oxygen gas)
