Critical review on dewatering of sewage sludge: Influential mechanism, conditioning technologies and implications to sludge re-utilizations.
Boran Wu,Xiaohu Dai,Xiaoli Chai +2 more
TL;DR: It is proposed that a unified theory for sludge dewaterability improvement remains to be established, as how the molecular structures of sludge compositions affect the solid-water interface behavior requires to be deepened, which will further unravel the mechanism behind strong water-holding capacities of bio-flocs.
Journal ArticleDOI
Correlation of physicochemical properties and sludge dewaterability under chemical conditioning using inorganic coagulants
TL;DR: The floc size and D(F) were increased after chemical conditioning, indicating that larger and more compact floc formed, and sludge dewaterability correlated well with the change in concentration of soluble EPS, LB-Eps and TB-EPS, but not with KV, D(f), flocsize.

A review of the properties of biosludge and its relevance to enhanced dewatering processes
TL;DR: The main purpose of all pretreatment methods is to modify the biosludge characteristics in such a way to boost settling of cells and solid particles of sludge, and to ease the release of water molecules from extracellular polymeric substances and cells and to facilitate flow of water through forming filter cake as mentioned in this paper.
