Zickert Z2000 bottom sludge scraper
The Z2000 Bottom Sludge Scraper is designed to provide continuous sludge transportation and performs well in all sedimentation processes, even in a sand trap. The Z2000 can be adapted to the most varied requirements because it is not dependent on where the operation is located and there is a choice between a hydraulic drive and an electric motor. The Z2000 also acts as a thickener.
This is how it works
The Z2000 is based on the forward and return motion of the hydrodynamically shaped profiles. The concave side of the profile pushes the sediment towards the sludge hopper, whilst on the return movement the tapered part wedges under the sludge blanket.
The shape of the profile is the result of extensive research. Experiments in test tanks have shown that the concave shape is the optimum solution for various types of sludge, different scraping speeds and the best possible thickening effect.

Zickert Z3900 surface sludge scraper
The Z3900 Surface Sludge Scraper is designed to remove surface sludge efficiently without taking away unnecessary transport water. It can be used in most applications where surface sludge occurs, both in municipal treatment plants and in industrial processes. It is easily adapted for tanks equipped for flotation or with lamella.
This is how it works
The Z3900 is easy to install, reliable and has few moving parts. The scraper blade scrapes the entire surface of the tank and removes the sludge to a discharge chute or a scraper table.
The Z3900 is characterised by an incremental movement. The drive rod has a forward and return motion. The scraper blade is attached to a slide, which is advanced in stages by the drive rod. The slide switches the direction of movement at the end positions. It allows several slides with scraper blades to be used in the same tank. The scraper blades can then work in conjunction. When returning the scraper blade pivots upwards to avoid the sludge.
