TLDR
Results indicate that the extraction of extracellular polymers by enzymes is a rather quick process reaching equilibrium within only a few hours, and generally gives a lower estimate of polymers compared to the CER method, but correctly detects the trends in the polymer quantity.About:

Pre-treatments to enhance the biodegradability of waste activated sludge: Elucidating the rate limiting step.
TL;DR: It is concluded that some pre-treatment techniques, such as thermal hydrolysis, thermal phased anaerobic digestion and low-temperature pre- treatment are effective ways to increase energy production and to improve other sludge properties,such as dewatering.

Zhan Chen,Zhan Chen,Zhan Chen,Weijun Zhang,Weijun Zhang,Dongsheng Wang,Dongsheng Wang,Teng Ma,Runying Bai +8 more
TL;DR: It was found that sludge filtration performance was deteriorated due to release of a large amount of biopolymers after enzymatic treatment, while the cake moisture reduction was favored at the optimal dosage of inorganic coagulants.

Surface properties of sludge and their role in bioflocculation and settleability
Bao-Qiang Liao,D.G. Allen,Ian G. Droppo,Gary G. Leppard,Gary G. Leppard,Steven N. Liss,Steven N. Liss +6 more
TL;DR: The results indicate that it is the surface properties, hydrophobicity, surface charge and composition of EPS, of sludge, rather than the quantity of EPS that govern bioflocculation, and in contrast, the EPS content is more important in controlling the settleability of sludges.
