The belt filter, currently considered the world’s most efficient and cheapest in operation, is a device for the removal of slurries from wastewater and simultaneous dewatering of sediment.

Principles of Operation:

The process of removing slurries consists of leaching sludge during transport on a filter net, from which the sludge is discharged into the screw thickener by compressed air. The dehydrated sludge has low humidity (often below 70) which facilitates further disposal.
