Title:
STERILIZING METHOD FOR ACTIVE CARBON IN WATER PURIFIER
Document Type and Number:
Japanese Patent JPH0290988
Kind Code:
A
Abstract:

PURPOSE: To apply electrical current uniformly to active carbon, generate Joule heat and heat sterilizing active carbon by applying voltage between electrodes in an active carbon cartridge.

CONSTITUTION: Active carbons 4, electrode plates 3 and a filter 2 are installed in a cylindrical active carbon cartridge case 1 in this order. Connecting terminals 31 connecting electric wires are provided on the electrode plates 3, and voltage is applied between electrode plates 3 to electrify active carbon 4 for heating. Thus, uniform electric current is applied to active carbon and Joule heat is generated to release uniform temperature distribution in the active carbon and carry out effective heat sterilization.
