• Mechanical Dewatering | SSWM Find tools for sustainable ...

    Dewatering can be done either with the help of presses or centrifuges (mechanical dewatering), filtration ( in filter bags) or physical (and biological) processes in drying beds. Mechanical dewatering and filtration often require the use of chemicals (coagulants and flocculants) to enhance the process.

In the conditioning operation, polymers are added to the sludge in order to promote particle aggregation, hence making dewatering easier. Depending on the dewatering technique, the socalled sludge cake reaches around 20 to 25% DS.
