Abstract: Various chemical disinfectants, such as chlorine, have a broad capability for destroying or deactivating microbes, but can produce harmful disinfection by-products. They also result in residual contamination by the disinfecting chemical. The application of high potential gradients to a liquid medium containing microbes also has a powerful disinfecting action. The combination of chemical disinfectants with the electric process leads to a compound process of great effectiveness, whereby the electrical process acts with greater efficiency and the amounts of chemical disinfectant required are substantially reduced.
