Abstract :
The inactivation of E. coli and total coli bacteria during pulsed corona discharge in the river water was investigated. The bacterial suspension of volume 157 ml was polluted with E. coli and total coli with concentration of 230 cfu/100 cm3 and 1500 cfu/100 cm3, respectively. The processing was conducted in a tube reactor with hollow needle-to-rod electrode system. The 2 min. of treatment caused decrease of total coli concentration by three orders of magnitude leaving only 3 cfu/100 cm3, which was E. coli. Obtained energy efficiency was 0.15 cfu/J.
