To produce PAW in a batch and continuous manner a multiple plasma device setup is used. The multiple plasma device consists of a series of plasma devices that are powered simultaneously to produce PAW. This multiple plasma device is powered by indigenously developed high-voltage high-frequency power supply. The air plasma generated in this multiple plasma device setup is electrically characterized and the produced radicals/species are identified using optical emission spectroscopy. The post-discharge effluent gases left after plasma-water exposure carries some environmental pollutants (NO x and O 3 , etc.). The batch and continuous PAW production setup utilizes effluent (pollutants) gases in production of large volume PAW. Hence, it substantially reduces the concentration of these pollutants in effluent gases which are released in environment.
