Plasma treatment

Plasma is ionized gas and is called the fourth state of matter. Plasma can technically be generated under atmospheric pressure from various gases (eg ambient air, nitrogen, oxygen, argon) and the plasma treatment of surfaces has reached a wide range of industrial applications.

 

The SPOWAR project partners Plasmatreat and Blue Plasma Agrosolutions will focus on the plasma treatment of water. Both partners have profound experience with the production of plasma equipment (Plasmatreat) and the application of Plasma (Blue Plasma and Plasmatreat).

 

Plasma has strong antibacterial (1) and oxidative properties and thus can be considered to treat water. Plasma treatment of water inactivates bacteria and the plasma-treated water itself acquires antibacterial properties (2,3). 

 

The SPOWAR project partners Plasmatreat and Blue Plasma use atmospheric pressure Plasma, either directly to treat water and thereby inactivating bacteria (3) and degrading pollutants or indirectly by immobilizing super catalyst on filter surfaces to achieve active water filter systems. Thin film coatings on various surfaces using plasma-enhanced chemical vapor deposition technology have proven to generate functionalized surfaces with various properties, among these antibacterial and bioactive coatings (4). 

 

Direct plasma treatment of water and active filter coatings are tested and evaluated for effectiveness of antibacterial properties and degradation of pollutants in wastewater.
