Inactivation of bacteria in water is demonstrated by using the pulsed‐power method. A large number of micro bubbles are successfully produced by injecting the pulsed power into the water, and then, shock waves are generated with collapse of the bubbles and the instantaneous heating of the water. The synergistic effect of the shock waves, electric shock, and radicals produced by electrical discharge may enhance the inactivation of bacteria. Bacillus subtilis as bacteria are released into the water in a water vessel. We found that 97% of the bacteria are inactivated by firing 100 shots of the pulsed‐power injection. The gross energy efficiency for inactivation reaches (0.6–8.8) × 10¹² CFU/kWh. © 2020 Institute of Electrical Engineers of Japan. Published by Wiley Periodicals LLC.

脉冲功率注入灭活水中的细菌

通过使用脉冲功率方法证明了水中细菌的灭活。通过将脉冲功率注入水中，可以成功产生大量微气泡，然后在气泡破裂和水被瞬间加热时产生冲击波。冲击波，电击和放电产生的自由基的协同作用可能会增强细菌的灭活作用。枯草芽孢杆菌作为细菌在水容器中释放到水中。我们发现，通过发射100次脉冲功率注射可以灭活97％的细菌。灭活的总能量效率达到（0.6–8.8）×10 ¹²  CFU /千瓦时 ©2020日本电气工程师学会。由Wiley Periodicals LLC发布。
