Abstract

The efficiency of transonic plasma system application for water purification to biologically clean water is experimentally demonstrated. The method is based on the formation of a high-speed two-phase flow with a double transition through the sound barrier with plasma generation in the supersonic flow zone. The first transition is caused by the formation of supersonic flow due to the formation of a two-phase gas-liquid mixture. The second transition is caused by a sharp deceleration of the two-phase flow and formation of subsonic single-phase flow regime, which is accompanied by a jump-like increase in static pressure and local generation of ultrasonic field; electromagnetic field; electrostatic field, etc. The experiments were conducted immediately after water intake from the Moskva River and with a week's cultivation of microorganisms in a cube tank at a temperature of 15-22°. After treatment, all tested samples met the quality indicators "drinking water" according to SanPiN 2.1.4.1074-01.
