The inactivation of Escherichia coli with bipolar pulsed dielectric barrier discharge in water-air mixture was studied experimentally. The relation of aeration amount initial content of bacterium, treatment time, electric intensity and conductivity to the inactivation rate of Escherichia coli was studied. Utilizing this system inactivation of Escherichia coli, the inactivation rate of Escherichia coli increased with increasing of the initial content of the bacterium, the electric intensity and the treatment...
