The ZICKERT Shark™ Bottom Sludge Scraper has over 3,000 installations all over the world, 90 percent of which are retrofits. It is designed for continuous sludge transport and performs well in all sedimentation processes, including grit chambers.
The scraper can be powered by a hydraulic or electric drive. A lever system and a number of wedge-shaped sections are welded together to form an integral frame so that they function as a moving floor in the tank.
The Shark is based on the forward and return movement of the hydrodynamically designed scraper blades. The concave faces of the blades transport the sediment toward the sludge pit. During the return movement, the wedge-shaped parts of the blades slide under the sludge blanket. The oscillating motion of the scraper blades also thickens the sludge as it's transported.
The ZICKERT Shark Scum Skimmer is designed for the efficient removal of surface scum without the excessive use of transport water. The skimmer blade draws scum from the entire surface of the tank and carries it to a scum pipe or scum beach. It is ideal for use in nearly all wastewater and industrial applications involving surface scum.
The scum skimmer is also versatile enough to adapt to flotation or inclined plate designs. The ZICKERT Shark Scum Skimmer is reliable, easy to install and has few moving parts
The ZICKERT Shark Cover is an efficient way to cover rectangular basins. Lightweight aluminum profiles mount across the basin and are molded to fit the UV-resistant membrane. Although simple and lightweight, the components are strong enough to meet applicable snow loads. Each section comes with a rope system so that the cover can be easily opened and closed by a single person.
The ZICKERT Shark Siphon is a straightforward solution for the continuous removal of sludge in rectangular sedimentation basins. Pipes are positioned vertically across the width of the tank and sludge is siphoned up through the pipes to a common trough.
The Siphon is sized for individual applications and to meet customer specifications. The system is cost-effective and requires very little maintenance and servicing. For best performance, the Siphon should be used with the Sludge Scraper to provide consistent high solids content.
