TL;DR: The results indicated that SDS and Triton X-100 have negative effect on the dewaterability of sludge pretreated both with and without electrolysis, but with a combination of CTAB (Cetyl Trimethyl Ammonium Bromide) and electrolysis pretreatment presented clear advantages over surfactant conditioning alone for improving sludge de waterability.

TL;DR: Acid-assisted S/S product showed lower De values and leaching tendency from TCLP test results for all the selected heavy metals (Ni, Cu, Zn and Pb) compared to traditional S/s product using the same binders.

TL;DR: The digestion system achieved rapid degradation of the organic substrate at 55 degrees C and the microbial diversity changed during the thermophilic process as thermophiles belonging to the Hydrogenophilaceae, Thermotogaceae, Clostridiaceae and the genus Ureibacillus replaced less temperature-tolerant microorganisms such as Sphingobacteriaceae or Trichococcus.
