Method For Removing PFAS in Liquids

VALUE PROPOSITION Per- and polyfluoroalkyl substances (PFAS) are a widely used but toxic and carcinogenic group of man-made chemicals. They are extremely resistant to degradation and will persist in the environment and in the human body. PFAS are highly water soluble, thus contaminated drinking water is the primary source of exposure. The most common...

Falling Bed Plasma Reactors

VALUE PROPOSITION A large variety of applications require powdered materials to be treated by plasmas. Most applications used in the industry and research labs have a static configuration, where the powder samples are placed in a tray and stay still during the process. This is ineffective if the powders pile up in multiple layers since the plasma...
