With a custom made hopper, the shaftless screw compactor gathers the solid waste from the screening or filtration systems.
The solid waste are conveyed to wards a compacting section with a shaftless screw conveyor, where they are compressed in order to reduce their volume and insure dewatering process.
A counter-pressure device at the end increases the overall performance of the unit.
Solid waste are discharged into a container or conditioned in a continuous plastic bagging system.
