Bound water content and water binding strength on sludge flocs

Advective Flow and Floc Permeability

“…Figures 6a-6c summarize the positions of the hydrogen bubbles, relative to the falling flocs A1, A4, and P4. For comparison sake, the numerical solutions of flow fields with scheme by Wu and Lee (21) are also depicted in these figures. Reasonable agreement is noted between experiments and the simulations.…”

Enhancing pulp and paper mill biosludge dewaterability using enzymes

“…This may include releasing the water trapped inside the flocs (Vaxelaire and C ezac, 2004) and/or increasing the particle size of flocs to reduce the surface area available for binding of water molecules. Although floc properties and their impact on biosludge dewaterability have been studied previously, the key properties and the degree of their impact on dewaterability are still not well understood (Jarvis et al, 2005a(Jarvis et al, , 2005bPark, 2002;Wu et al, 1998).…”

Phase change heat transfer of biological aggregates

“…Lee t45] proposed that the capability of bound water to resist freezing at sub-freezing temperatures is attributable to its low thermodynamic activity, being contributed by the interaction strength between water and solid phase. Wu et al [46] estimated the water-solid strength of bound water for three different sludges using the thermodynamic analysis, considering the effects of solid contents on the moisture distribution. Chen et alE47] proposed a continuous moisture classification scheme using water-solid strength as an index.…”
