The ClearFox® DiOx EO (electrical oxidation) is a specialized process technology that uses diamond electrodes and electrical current to oxidise a wide range of hard to treat pollutants. These include inert COD, heavy metals, and persistent substances. EO can be applied in all applications where it is necessary to oxidate inert organic matter. The ClearFox® DiOx EO Modules includes several stacks, and each of them comprises several square meters of HQ diamond coated electrodes. ClearFox® DiOx modules can handle flowrates from 1 m³/hr to 400 m³/hr.

Advanced pollutant removal technology with boron doped diamond electrodes
Modular EO technology can be supplied in container modules or can be installed in site built concrete tanks. The ClearFox® DiOx uses diamond coated electrodes that can achieve a wider range of pollutant removal and a higher removal efficiency than standard electrodes, making it the leading electrical oxidation process technology on the market.
There is no limit or restriction on the size of the project that our ClearFox® DiOx systems can be utilized for, as the system is modular. The DiOx modules can be used in conjunction with other ClearFox® process technologies as part of a complete industrial wastewater treatment solution, or they can be installed as a standalone solution. Complete solutions can be supplied, or the DiOx equipment can be installed within existing tanks onsite.
The EO ClearFox® DiOx is particularly suitable for applications such as:
- Produced water from oil drilling
- Produced water from gas exploration
- Pharmaceutical wastewater
- Wash water from plastic recycling industry
- Printing wastewater
- Textile wastewater
- Power industry wastewater
- Automotive industry wastewater
- Semiconductor industry wastewater
EO can be applied in all applications where it is necessary to oxidate inert organic matter. The ClearFox® DiOx EO Modules includes several stacks, and each of them comprises several square meters of HQ diamond coated electrodes.
Diamond coatings are recognised for their extreme stability and long lifetime. The major benefit of the HQ diamond coating is that, during the oxidation process, hydroxyl radicals are also formed, which have a high disinfectant effect in wastewater. The power consumption is very low and there are no residual substances.
The ClearFox® modules are very user-friendly, packed in highly resistant casings, and can be maintained easily.

THE PROCESS TECHNOLOGY
The ClearFox® DiOx Electro-oxidation (EO) is a process technology used for industrial wastewater treatment. It comprises two electrodes operating as anode and cathode, connected to a power source. When an energy input and sufficient wastewater are provided to the system, strong oxidizing species are formed, which interact with the contaminants and degrade them. The electrode material has a major impact on the system efficiency. With our diamond coated electrodes offering superior pollutant removal than normal electrode materials.
ClearFox® DiOx can be implemented for the removal of a wide variety of harmful and non-biodegradable contaminants, including aromatics, pesticides, dye, heavy metals, etc. In combination with the ClearFox® DAF and FBBR it offers the ability to totally clean and treat industrial wastewaters, making them suitable for reuse.
The ClearFox® DiOx uses diamond coated electrodes. Diamond coated electrodes exhibit strong chemical and electrochemical stability, good conductivity, extreme resistance to corrosion and a very wide potential window. This makes the diamond coated electrodes superior to other types. The corrosion resistance also means that they are especially suitable for the treatment of wastewaters with a very high TDS such as oil and gas produced water, landfill leachate and other highly polluted industrial wastewaters. For this reason, DiOx is considered as the most effective electrode type for mineralization of organic pollutants, providing high efficiency as well as lower energy consumption (OPEX) when compared to all other electrodes.
