Dynamics of dewaterability and bacterial populations in activated sludge
Water Science and Technology, 2012 Relationships of bacterial populations and extracellular polymer substances (EPS) to dewaterability of activated sludge were studied on three laboratory-scale activated sludge reactors fed with synthetic wastewater. Dewaterability of activated sludge was evaluated by a novel method developed by the authors, in which small amount of sludge was ...

Water and Environment Journal, Volume 40, Issue 3, Page 484-494, August 2026.This graphical abstract shows the overall study design where dewatered wastewater sludge samples were collected and subjected to a range of HT temperatures. Measurement of nucleic acid concentration and antibiotic resistance gene profiles across temperatures showed that HT at moderate temperatures offers sustainable, scalable sludge sanitation and ARG ...

Use of a water treatment sludge in a sewage sludge dewatering process
E3S Web of Conferences, 2018 The objective of the research study was to determine whether a sewage sludge conditioning had any impact on sludge dewaterability. As a conditioning agent a water treatment sludge was used, which was mixed with a sewage sludge before a digestion process.

Thermophilic versus Mesophilic Anaerobic Digestion of Sewage Sludge: A Comparative Review
Bioengineering, 2016 During advanced biological wastewater treatment, a huge amount of sludge is produced as a by-product of the treatment process. Hence, reuse and recovery of resources and energy from the sludge is a big technological challenge.

The Canadian Journal of Chemical Engineering, Volume 103, Issue 10, Page 4786-4802, October 2025.Abstract Oil sands exploration generates large volumes of mature fine tailings—mixtures of clays, water, and residual bitumen—that remain stable even after settling in tailings ponds for many years. Commonly used flocculants, such as neutral and anionic polyacrylamides, destabilize the colloidal interactions between the clay particles, but ...
