PURPOSE:To remove chlorine odor from city water flowing in a large amount, by using a specific felt-shaped fibrous active carbon for domestic water purifier as filter medium. CONSTITUTION:A fibrous active carbon consisting of the cellulose or regenerated cellulose featuring a specific surface area of no less than 1000m<2>/g and a diameter of 5-30mu is made resistant to flame and activated. It is then shaped into the form of a felt having an apparent density of 0.07-0.25g/ml and thereafter immersed in a silver nitrate solution on which to deposite the silver of 0.2-5wt.%. The resulting felt-shaped active carbon fiber is filled directly in a water purifier, whereby the deodorizing effect for chlorine odor at a high speed of flowing water lasts longer and the disinfacting effect is also fully exerted. |
