Our device used to generate intensive NTP in bubbling water is shown in Fig. 1. The length of the
glass tube in this figure is 50 cm, and the inner diameter of the tube is 3.6 cm. Cold plasma enables both
the UV radiation and active species like O and OH radicals to be generated within the gas bubbles,
which effectively destroys biologically harmful contaminants (not only pathogens, but toxic chemicals
as well) in the treated water without attendant heating
