Use of a water treatment sludge in a sewage sludge dewatering process

open access: yesE3S 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.

Controlling polymer addition flowrate to improve the flocculation of kaolinite suspensions as models for oil sands mature fine tailings

open access: yesThe 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 ...
