Dynamic viscosity of wastewater sludge
WebApr 29, 2024 · The Fenton reagent (Fe 2+ /H 2 O 2) reduces the apparent viscosity, whereas Fe 2+ /Na 2 S 2 O 8 leads to a higher apparent viscosity, and the apparent viscosity of Fe 2+ /KHSO 5 conditioned sludge is similar to that of raw sludge. In summary, the changes in filterability and apparent viscosity are not consistent for the … WebThe residue that accumulates in sewage treatment plants is called sludge (or biosolids). Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. This residue is commonly classified as primary and secondary sludge. Primary sludge is generated from chemical precipitation, …
