Water treatment

For water treatment, reactive plasma species are generated by the microplasma technology (SMD) in the air and added into the water via a diffuser. The plasma species dissolved in water are able to inactivate microorganisms (bacteria, viruses, etc.) in short time. Depending on the plasma design (electrical parameters and geometric structure) a continuous or temporary effect of the plasma-activated water can be achieved.

Areas of application of plasma-activated water:

  • Treatment of bacterially contaminated water to regain drinking water quality
  • Treatment of domestic and industrial water with different quality demands for commercial, industrial, agricultural or similar purposes, such as swimming pools, irrigation systems, toilets
  • Treatment of microbiologically contaminated wastewater
  • Reduction of microorganisms on surfaces after cleaning or rinsing processes using plasma-activated water


However, a filter effect cannot be achieved by cold plasma.
