DESORTION ISOTHERMS OF DOMESTIC ACTIVATED SLUDGE

摘要

Most of the studies dealing with water repartition within activated sludge focus essentially on the transition between free water and bound water; a transition which is important for mechanical dewatering investigations. But nowadays the drying of sludge is increasing and a better characterisation of the bound water is necessary. In this study a simple technique for the evaluation of sorption isotherms is presented.
