How effective are Magneli phase Titanium Oxide powders for water disinfection?

Magnéli phase titanium oxide powders, especially Ti4O7, are highly effective for water disinfection primarily due to their excellent electrical conductivity, chemical stability, and catalytic properties. They serve as anodes in electrochemical water treatment systems, enabling advanced oxidation processes that mineralize pollutants such as PFAS, ammonia, and other emerging contaminants.

Key benefits of Ti4O7 in water treatment include:

• Facilitating electrochemical oxidation of persistent pollutants, achieving effective mineralization where traditional methods fail.

• Integration into reactive electrochemical membranes (REMs), which combine membrane filtration with electrochemical oxidation, enhancing contaminant removal efficiency by providing a reactive surface and filtration in one unit.

• Offering a cost-effective, low-maintenance, and on-site adjustable disinfection method without requiring chemical disinfectants, thus reducing operational complexity and chemical handling risks. We offer pilot scale systems to test in your environment, that can be implemented full scale after testing and budget decisions.

• Compatibility with renewable energy sources such as photovoltaic power, enabling off-grid water treatment solutions

  
  

Ti4O7's electrical conductivity (~1000 S cm⁻¹) surpasses that of graphite, and its chemical inertness ensures durability in harsh water treatment environments, supporting long operational lifetimes (estimated 10+ years under industrial conditions). This makes Magnéli phase titanium oxides a promising advanced material for sustainable and efficient water disinfection and pollutant mineralization. We have developed our anodes and systems to take advantage of this and we work with companies and counties across the US who are grappling with finding a cost effective solution to removing PFAS at scale.
