Abstract: Conventional processes of water disinfection can generate toxic composites. It is the case of the trihalomethanes (carcinogenic) formed in the contact of chlorine with organic substances present in the water. The electrolytic treatment can be a substitute for the chlorination process without the need for addition of chemical substances to the process. The effect of the electrolytic treatment using carbon cathode on the viability of the microorganism Bacillus subtilis was tested to determine the death process. … Show more

“…The intended products are responsible for the disinfection of water [30]. These studies are consistent with the study by Rahmani in 2005 [28]. Rahmani showed that increasing the voltage from 8 to 25 V and reducing the distance from 8 to 2 cm leads to an increase in the efficiency of E. coli bacteria removal at the rate of 1 colony/liter [10].…”

“…Also, increasing the contact time up to 15-75 min increased the process efficiency [27]. Rahmani et al investigated bacterial elimination by electrolysis and found that the amount of removal would depend on the voltage and duration of electrolysis and that the removal efficiency is higher at higher voltages [28]. The bacterial mortality during the electrochemical process involves the production of chemical disinfectants such as chlorine and ozone, flux transfer in the bacteria-electrode interface, the destruction of the cytoplasmic membrane and increased cell membrane permeability [29].…”

“…Tolentino-Bisneto e Bidóia 22 trabalharam com a eletrólise de Bacillus subtilis e observaram que as células ficavam com material de lise e tamanho comum reduzido, além de também ter sido observado um extravasamento do citoplasma. Após 30 min de eletrólise, a parede das células apresentou buracos e parte do citoplasma escoou como resultado da eletroporação irreversível.…”
