ABSTRACT
Chemical ways are widely used for sterilizing drinking water like ClO (dioxide chlorine) and chlorine. Electrical conductivity (EC) indicates how water transports the electric charge, as well as the effect of the water chemical composition on the EC. EC has an important role in inactivation of microorganisms. The differences in the electric conductivities with the changing electric field depend on the quantity of salts, current, voltage, temperature, food properties, and pH. Elimination of bacteria is done by electroporation of the cell membrane by the electrical field and electrical current. Moreover, electroporation leads to exceed the specific dielectric strength in the cell membrane because of the increase of the electric field. The exponential equation is representing to the relation between the time and outlet microorganisms. The use of electrical field as a nonthermal treatment for water is a novel technology. A continuous nonthermal disinfection device is used for disinfecting drinking water by low electrical field.
