Title: Water sterilizing method
Inventor: NONOYAMA NOBORU
IPC: C02F1/48
Filed: 1989-04-27
Abstract: PURPOSE:To sterilize water without using an oxidizing agent-based fungicide such as chloride by impressing a high-voltage pulse with specified electric field strength and pulse width on the water to be sterilized. CONSTITUTION:When a high-voltage pulse is impressed on the water contg. bacteria, the electric energy is impressed on the cell walls of bacteria and transduced into mechanical membrane compressing energy, hence the cell walls of bacteria are broken, and the bacteria are destroyed The electric characteristic of the high-voltage pulse necessary to break the cell walls of bacteria differs to some extent depending on the kinds of bacteria and the amt. of an electrolyte in water. However, the water can be almost surely sterilized by controlling the electric field strength to 10-50kV/cm and the pulse width to about 100-1000musec. Since a chemical is not used in this method, the method is advantageously applied in sterilization especially when pure water is produced. In addition, as this method is not affected by the reducing matter dissolved in treated water and pH, sterilization is surely achieved even when the water quality is fluctuated.
