Evaluation of hydrophobically associating cationic starch-based flocculants in sludge dewatering [PDF]
Two series of binary graft cationic starch-based flocculants (CS-DMCs and CS-DMLs) with different hydrophilicity and charge density (CD) were prepared by graft copolymerization of acrylamide with 2-(Methacryloyloxy)-N,N,N-trimethylethanaminium chloride ...

Hydrothermal Carbonization of Sludge – Optimization for Dewaterability
Anaerobic sludge digestate (SD), a by-product from anaerobic digestion, can be used as fuel. However, the high moisture content and poor dewatering properties makes SD unfit for direct energy applications such as combustion and thermal gasification ...

Settleability and Dewaterability of Sewage Sludge with Modified Diatomite [PDF]
Abstract In this study, cationic polyacrylamide (CPAM) modified diatomite and cetyl trimethyl ammonium bromide (CTAB) modified diatomite were synthesized and used as conditioner in sewage sludge dewatering. The effects of these two types of modified diatomite on the dewaterability and settling performance of activated sludge were studied.
