ZICKERT Shark™ Clarification System

January 3, 2012

The ZICKERT Shark Sludge Scraper provides an innovative solution for settled sludge transport in rectangular tanks and lamella plate clarifiers. It is based on the forward and return movement of hydrodynamically designed sections. The concave faces of the sections transport the sediment toward a sludge pit. During the return movement, the wedge-shaped parts of the sections slide under the sludge blanket, providing continuous and uninterrupted transport of the sludge. With over 3000 installations worldwide, the ZICKERT Shark can be applied in wastewater treatment plants, drinking-water purification plants and industrial processes. Designed for continuous sludge transport, it performs well in all sedimentation processes, including grit chambers. The Shark has a robust and simple design with few moving parts. It can be powered by hydraulic or electric motors and provides the same exceptional results whether it is pulled or pushed, offering immense flexibility when locating the drive. The ZICKERT Shark is simple to install and easy to maintain. Most importantly, it provides complete sludge transport, leaving no dead zones and creating no turbulence.
