Emo FranceSludge dewatering
Sludge dewatering stands for a strong increase in dryness, modifies the physical status of sludge, those passing from the liquid state in a pasty or solid state.
Belt filter presses and centrifuges give rather pasty sludge because of perfor-mances from dewatering which can reach as a maximum 18 to 20% of dryness for the first family of equipment, and 20 to 25% of dryness for the second.
On the other hand, plate filter presses produce sludge of solid structure (30 to 35% of dryness) thanks to the combination of a conditioning wuith slaked lime wash and high.
