Belt press is widely used in sludge dewatering units for the disposal of excess active sludge in biological aeration units of domestic wastewater treatment plants.

Sewage treatment plant's sludge drying units generally projected with a belt press because of the its continious working priciple.

Polymer dosage unit and monopomp is required during operation of belt press.

Unlike filter press machine; with its mechanical system, sludge dewatering can be carried out continuously without requiring manpower. It is the centrifugal decanter equipment in another equipment which can make sludge dewatering in continuous system.

The operating system is designed to separate solid particles from the liquid phase by the squeezing pressure between the drums and the sludge pumped at the fixed flow through the monopomp.
