WATER-TREATMENT BY PITCH-BASED ACTIVATED CARBON-FIBER

Recently lakes, swamps and suburban rivers of cities have become growi ngly polluted according to various kinds of waste water drainage. For domestic and industrial waters much call has been made on advanced wat er treatment techniques to where more adsorption operation is employed by granular and powdered activated carbon for removal of organic subs tances, color, odor, etc. We already succeeded in a promising result f rom two experiments at Kashiwai Water Works of Chiba Prefecture and Mu rano of Osaka Prefecture using a pitch-based activated carbon fiber (A CF). This paper deals with the further development that the pitch-base d ACF has been reformed and the development of higher performance ACF ventured on.
