Belt presses are commonly used in sludge dewatering units for the drainage of surplus active sludge in domestic wastewater treatment plants’ biological aeration units. Because of its continuous operating concept, sewage treatment plants’ sludge drying units are normally equipped with a belt press. During the operation a polymer dosage unit and a monopomp are also needed.
The squeezing pressure between the drums and the sludge pumped at a fixed flow through the monopomp is intended to isolate solid particles from the liquid phase.
Perform Without Manpower
In contrast with a filter press machine, belt press sludge dewatering can be performed continuously without the use of manpower due to its mechanical method.

Here is more equipments for the Sludge Drying category.
Filter press equipment are sludge dewatering in wastewater treatment plants and mechanical machines which make solid-liquid separation in industrial filtration applications.
Instead of filter presses and belt presses, centrifugal decanters are used as sludge dewatering units in urban and industrial wastewater treatment plants.
