The efficiency of water disinfection using a ceramic water filter and electrochemical hybrid system was investigated. Escherichia coli O157:H7 was effectively inactivated even when a storage battery, charged using a solar panel device, was used for the electrolysis process. During electrolysis, the rate of microbial inactivation was higher at higher initial Cl− concentrations. This was because of the higher CT value (the disinfectant concentration, C [mg/L], multiplied by the exposure time, T [min]) of free chlorine. Microorganisms were effectively inactivated under low pH and high temperature conditions. Disinfection by-products, such as trihalomethanes (THMs) and haloacetic acids (HAAs), were below the standard concentrations allowed in drinking water by the US Environmental Protection Agency.
