Sludge dewatering | IDRECO S.r.l.
Before sludge enters the press it is chemically conditioned for dewatering with an emulsion polymer flocculant that helps form stronger flocs. After chemical conditioning, a transfer pump drops the sludge onto a preliminary dewatering belt where free water molecules separate by gravity and fall into a collection trough.

Polymers for Water and Wastewater Treatment
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 ...

· If no liquid passes through the filter, the waste is deemed solid and can be disposed of more cost-effectively than liquid waste. In industry, we would consider sludge passing the paint filter test to be dewatered. Polymer flocculants expedite the dewatering processing by allowing water to leave the flocculated solids more freely.
