- Scraper blades can be lifted above the top edge of the basin (optional)
- Complete scrapers in stainless steel on request
- Long service life due to high-quality materials
- Large tank widths / carriageway widths possible:
up to 15 m: single scraper system
up to 30 m: twin scraper system
Suitable for the following markets
The Passavant® longitudinal scraper in bridge design spans one or more adjacent longitudinal tanks. The blade scraper pushes the settled sludge against the direction of flow into a sludge collection hopper at the inlet, while the suction scraper conveys the settled sludge directly from the bottom of the tank into a collection trough.
Optionally, sludge discharge is possible in both directions of flow, allowing higher sludge quantities with shorter sludge residence time. The floating sludge is cleared in the direction of flow to the outlet end of the sedimentation tank and removed from there.
For safe year-round operation, regardless of ice, snow, and rain-soaked roadways, Passavant® scrapers can be equipped with forced drive via rail and rack.
Passavant® ensures robust and proven clearing technology with a long life cycle and long-term spare parts availability.
