Electrochemical processes have gained increasing interest in recent years for the treatment of polluted waters.

 

They are considered to be versatile and capable of degrading a wide range of contaminants, including refractory carboxylic acids1,2 and even perfluorocarboxylic acids (PFCA).

 

3,4 Electrochemical systems offer several advantages over other approaches, such as:

• operation at ambient temperature and pressure

• robust performance and capability to adjust to variations in the influent composition and flow rate

• they generally require no auxiliary chemicals and do not produce waste

 

Electrochemical processes can be adapted to various applications, and can be easily combined with other technologies.  The modular design and small footprint of electrochemical systems also make them attractive for decentralized wastewater treatment.

​

While the advantages of Electro Chemical Oxidation have been known and documented for many years, the technological barrier had been an anode material that has high over-potential, durable in harsh environments, that could withstand high current densities, and also be commercially affordable.  

 

Magneli Materials has developed coating technology, using Ti4o7 and low cost substrate material to produce anodes that allow Electro Chemical Advanced Oxidation systems to be created in the both the drinking water and industrial waste water treatment industry. This allows new treatments for PFAS and Nitrogen and to be implemented at full scale, while still being affordable.

 

Magneli Materials provides anodes, cathodes, and reactors for the industrial and drinking water industries.
