This　paper　presents　sewage　sludge　to　produce　an　adsorbent　for　Direct　Fast　Brown　M　removal.　The　optimal　conditions　for　a　larger　surface　area　adsorbent　were　4　M　ZnCl2-immersed　sludge　pyrolyzed　at　550°C　for　60　min,　the　highest　BET　surface　area　and　micropore　area　achieves　174　m2/g,　and　95　m2/g,　respectively.　The　experiment　to　adsorb　the　Direct　Fast　Brown　M　waste　water　was　carried　out.　It　is　noteworthy　to　point　out　that　more　than　80%　reduction　in　COD　value　has　occurred　for　wastewater　sample.　Experimental　results　demonstrate　that　sewage　sludge,　a　waste　material　in　abundant　supply,　is　a　viable　source　of　activated　adsorbents.　©2009　IEEE.
