This equipment is mainly dedicated to the treatment of rejections of screening,
Sludge and sand in the treatment of urban or industrial waters.
The waste falls into the conveying screw via an inlet hopper inside the transport zone, the residual water is filtered in the drainage zone.
The rotational movement of the screw, driven by a gear motor, drives the waste to the outlet of the conveying screw or to the compaction zone.
In the case of a compacting screw, the waste accumulates on the outlet flap, which is kept closed by an adjustable pressure spring hinge, compacts on the flap and evacuates as soon as the pressure on the flap is sufficient To open it.
The compaction zone is equipped with a perforated sheet strainer and a receptacle connected to the drainage zone by a pipe in order to recover the filtrates due to compaction.
A washing ramp, to be powered intermittently, allows cleaning of the strainer. The compaction zone can be equipped with an optional frost protection.
