| The purposes of this study were to investigate adsorption characteristics and economical valuation of activated carbon for water purification. This study considered removal characteristic organic matter such as KMn0_4 consumption, DOC, UV-254 and THMFP and manufacture cost were compared with different commercial activated carbons for water purification. At packed pilot plant, the result of compare with adsorption removal rate KMn0_4 consumption, DOC, UV-254 and THMFP based activated carbon is in case of KMn0_4 is expressed blend coal(51% ), bituminous coal(51% ), coal-based (53%), coconut- based (51%) and wood based activated carbon(38%) and in case of DOC is expressed blend coal(39%), bituminous coal(32%), coal-based(42%), coconut-based(36%) and wood based activated carbon(34%) and in case of UV-254 is expressed blend coal(53%), bituminous coal(47%), coal-based (54%), coconut-based (45%) and wood based activated carbon(38%) and THMFP adsorption removal rate is expressed blend coal(56%), bituminous coal(46%), coal-based (59%), coconut-based (55%) and wood based activated carbon(37%). Therefore, removal efficiencies of organic matteris superior to coal-based activated carbon. Moreover, used manufacture cost by anthracite and bituninous coal is ￦854,000/ton, it is possible to made ￦100,000/ton. consideration through 15% as corporation profit, finally, we can made activated carbon that have economical efficiency. |
