Comparison of electrochemical method with ozonation, chlorination and monochloramination in drinking water disinfection

► Electrochemical, O3, NaClO and NH2Cl were compared at respective optimal condition. ► Disinfection efficacy was similar for different bacteria in electrolysis. ► Harsh Bacillus was inactivated more difficult in O3, NaClO and NH2Cl system. ► Efficient disinfection of electrolysis was attributed to nonselectivity of
- OH. ► Cell surface damage was more obvious in electrochemical process than the others.
