Abstract: This work investigates the constant-pressure consolidation characteristics of three different sludge samples, with particular emphasis on the tertiary consolidation stage. The refined Terzaghi-Voigt rheological model is ...

Abstract: This work investigated the effects of cationic polymer flocculation on the continuous moisture distributions of two sludges by means of combined thermal gravitational analysis and differential thermal analysis tests. At a ...

Abstract: This work examines the thermal pyrolysis characteristics of polyelectrolyte-flocculated activated sludge at a heating rate up to 873 K by means of thermogravimetric analysis (TGA). Although the polyelectrolyte does not ...

Abstract: In this work we investigated the use of a short time, low superheat boiling process to treat biological sludge. The treated sludge would exhibit a deteriorated filterability, and a marked increase in soluble organics ...
