HUBER Screenings Wash Press WAP® A cost-effective method of screenings washing for any application

The screenings to be treated are discharged directly from a screen or conveyor (e.g. screw conveyor) into the feed trough of the Wash Press. A robust conveying and com­pacting screw transports the screenings into the wash zone where they are exposed to directed and powerful turbulence created by automatic introduction of wash water (service water).

The turbulence achieves perfect sep­aration of organic particles and thus effective screenings washing. The washing intensity and cycles are individual­ly adjustable.

The washed screenings are further conveyed in the rising pipe to the press zone where they are pressed and dewa­tered by the compacting screw to a DR content of 35 - 45 %.

The wash water from screenings compac­tion which is rich in carbon is discharged back into the waste water stream. Automatic cleaning of the wash water collecting tank under the machine is possible.

The washed and compacted screenings are finally transport­ed through the conical discharge pipe into a skip. For an optimised maintenance strategy, machine sizes 2-12 are equipped with wear detection of the compact­ing screw in the press zone. The system automatically detects the ideal time for maintenance of the auger.
