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

SCREW
The shaftless screw is manufactured in special hardened steel and lay on a PEHD protection. The rotation speed is set according to each application. The screw is maintained in its axis thanks to the trough shape.
DRAINAGE ZONE
At the screw bottom, a drainage zone option can be fitted in order to collect the water extracted from the solid waste, especially when the unit is installed inclined.
COMPACTING ZONE
The compacting grid is designed with two dewatering steps. The first step is insuring positioning and centering in its axis. It is designed with stainless steel perforated plate with larger openings than the second step with a slotted plate, allowing pre-dewatering before the ultimate pressure step for proper solid waste dewatering.
