Rotating sludge scraper

With 90% of sludge settlement tanks estimated to be circular in the UK, the innovative Zickert 3700 is suitable for retrofit as well as new installations. It achieves the same lower-energy and high-sludge performance of rectangular Zickert scrapers and is suitable for primary, humus and final settlement tanks.

The unit features an innovative peripheral drive and rotating scraper design.  The electrical drive is located on the perimeter tank wall with a static electrical connection point meaning no sliprings are needed. The bottom scraper blades are rotated via a circular ladder rail inside the tank wall, moving settled sludge to the collection point.
