Sludge characteristics
Webb10 mars 2024 · In general, when the moisture content of the sludge exceeds 90% by mass or weight, the sludge behaves as a Newtonian fluid, whereas below 90% it behaves as a non-Newtonian fluid in a way similar to those of some polymers (both certain … WebbThe data showed that WWTPs contained highly varying concentrations of Na+, Al, and Fe in the wastewater and that these cations were responsible for differences between WWTPs as to sludge dewatering rates and effluent quality. In general, a high influent Na+ concentration caused poor sludge dewatering and effluent characteristics.
