The bactericidal effects of electrochemical system containing steel mesh electrode were evaluated from contaminated water with E. coli, Pseudomonas aeroginosa, Staphylococcus aureous and Streptococcus fecalis at various concentrations. Effect of current density, supporting electrolyte and pathogenic bacterial concentration were studied and kinetic rate of disinfection were determined. The obtained results show, the effect of current density on disinfection efficiency was highest and then concentration of bacteria in the contaminated water and supporting electrolyte concentrations in the electrolyte have more effective. Contaminated water including 100 and 1000 bacteria/ml of Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and streptococcus faecalis, compeletly disinfected using 0.088 mA/cm2 current during 5 to 60 min. The reaction rate of disinfection is directly related to current density. It is expected that experimental results could be used as a reference for the elimination of pathogenic bacteria using electrochemical process.
