“…1). In the hydrolysis stage, biomass materials are broken down to become low-molecular weight compounds such as oligosaccharides, glucose (or fructose), and amino acids (Funke and Ziegler, 2010;He et al., 2013) which can be occurred in the temperature range of 100-175 C (Abelleira et al, 2012). The carbonization stage consists of the solid-solid conversion, dehydration and polymerization/aromatization reactions which require relatively high temperatures in the range of 160-280 C (Falco et al, 2011).…”

Hydrothermal carbonization (HTC) is a thermal conversion process which converts wet biomass into hydrochar. In this study, a low-energy HTC process named "Two-stage HTC" comprising of hydrolysis and carbonization stages using faecal sludge as feedstock was developed and optimized. The experimental results indicated the optimum conditions of the two-stage HTC to be; hydrolysis temperature of 170 °C, hydrolysis reaction time of 155 min, carbonization temperature of 215 °C, and carbonization reaction time of 100 min. The hydrolysis reaction time and carbonization temperature had a statistically significant effect on energy content of the produced hydrochar. Energy input of the two-stage HTC was about 25% less than conventional HTC. Energy efficiency of the two-stage HTC for treating faecal sludge was higher than that of conventional HTC and other thermal conversion processes such as pyrolysis and gasification. The two-stage HTC could be considered as a potential technology for treating FS and producing hydrochar.

“…However, unlike the standalone thermal treatment that has been a proven technology [2,3] or its coupling with other chemical conditioners (acid [14,15], alkaline [10,15], or Fenton's reagent [16]) that have been earlier studied; the coupling of inorganic coagulant addition with thermal conditioning has only been recently studied. It was found that temperature escalation to 90°C resulted in solubilizations of protein and carbohydrate which provided more binding sites for the hydrolyzed metal cation [12].…”

A study for producing low moisture content sludge cake was performed by adding NaCl, CaCl 2 , Ca(OH) 2 , or FeCl 3 to excess sewage sludge under hydrothermal treatment (HT) and varying dewatering conditions from low to high pressure (0.04-12 MPa). FeCl 3 addition under HT resulted in cakes with significantly lower moisture content than HT cakes, and moreover, than raw sludge cakes, under all dewatering conditions. The addition of CaCl 2 produced similar effects to FeCl 3 addition but at weaker extents. The addition of Ca(OH) 2 produced much weaker effect than the addition of CaCl 2 under the low-pressure dewatering. However, the effects were comparable under the medium-and highpressure dewatering. The effect of NaCl addition was only prominent under the high-pressure dewatering. Comparison on the moisture content of sludge cakes with the treatments of HT, coagulant-added, and their combination showed that synergy between HT and coagulant addition in producing low moisture content sludge cake was evidenced.
