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 study considered the removal efficiency of turbidity and organic content from high-turbidity storm water of tropical storm Nari, using polyaluminum chloride (PACl) as a coagulant. The resulting floc size and compactness ...

Abstract: Dual conditioning of activated sludge utilizing polyampholyte (T204) in combination with ferric chloride or cationic polyelectrolyte, polydiallyldimethyl ammonium chloride (PDADMAC) was investigated. Capillary suction time, ...

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: Bound water content is generally taken as an index for differentiating the moisture content in a sludge. However, some recent works have demonstrated that such an index is an operationally defined value differing markedly ...

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 ...

Abstract: The Hsinchu Science-based Industrial Park (HSIP) is the main manufacturing base of “high-tech” commodities of Taiwan. The treatment of wastewater of HSIP produces hard-to-dewater sludge, at a rate of 80 Mg/day, which is ...

Abstract: Dynamic responses of the blanket in full-scale flat-bottom type floc blanket clarifiers at the PingTsan Water Works, Taiwan Water Supply Corporation, were monitored given a step-change in coagulant (polyaluminum chloride, ...
