In the influence of a microwave energy field, the gas filling a variably shaped glass case is turned into plasma which emits UV light in desired wavelengths depending on the choice of gas or gas mixture in the case. The laminar homogeneous emission of light reduces the formation of biofilms or surface layers.
Maintenance is easy as the active electro-technical components are located outside those parts of the apparatus which are in contact with the medium giving the apparatus a long operating life. The system is reliable and economic as it can sterilize even high volume streams of water when the correct shape of lamp is chosen.
Modified and equipped with the proper gases to emit the required light spectra, the system can even be used to oxidize persistent organic compounds in oxidation processes for treating water.
