Simulation of liquid phase accumulation at centrifugal dewatering of activated sludge [PDF]

, 2005
Centrifugation of activated sludge is a frequently used dewatering process but there is a need for a fitting function for moderate and high sludge concentrations. In particular, liquid phase accumulation kinetics during centrifugation may be used as a

Quaternization-based graft modification of straw fibers for conditioning the sludge dewatering performance

Water Science and Technology
Extracellular polymeric substances (EPS) are a critical influencing factor in sludge dewatering. Disrupting such EPS contributes to the release of bound water in sludge, enhancing the sludge dewatering performance. In This study, quaternized straw fibers
