ClearStream Thickeners
Thickeners are used in municipal, industrial and minerals applications to take solids from other liquid solids separation processes and thicken the solids prior to further dewatering. The drive is mounted on the walkway or bridge. The rotating portion of the drive turns a structural torque tube or shaft, which in turn rotates the solids removal mechanism.
ClearStream cage driven and center column supported thickeners can be supplied in sizes in excess of 400’ diameter.

Rakes with Pickets
As the pickets pass through the solids, they create channels which allow the water to escape. This release of water produces a higher percent solids. This design works best and heavier solids which tend to trap the water within the solids layer.
Blades on Posts
Blades on posts are another option to deal with heavy solids. This design in effect raises the rake structure out of the solids layer. The result is that the rake structure is not dragged through the solids layer. This in turn reduces the torque required to rake the solids to the center sump. This design is employed and applications that have a heavy solids layer.
Low Profile Rakes
Low profile rakes are another option to reduce the torque required for thickening solids. Rather than the traditional rake cage design, the rake arm is constructed either out of heavy-duty channel or a specially constructed box beam. In either design, the surface area of the rake mechanism is greatly reduced thus producing and equivalent reduction in the torque required to turn the rakes through the solids layer.
Auto-dilution Feedwell
An auto-dilution feedwell is used in mineral application to enhance the mixing and use of polymer dosing and reduce short-circuiting of the feed coming into the feedwell, which in turn, provides a more efficient and uniform settling of the solids.
Heavy Duty Drive Units
ClearStream can design Shaft or Cage Drives with lifts to accommodate any applications with high or heavy solids loads.
These drives use the robust primary and secondary reducers and precision main gear/bearings. They also include torque measurement display with an easy-to-read torque dial.
3D Models of Every Project
ClearStream develops a detailed 3D model for every unit manufactured, ensuring accurate fit-up and seamless integration with site-specific layouts. These models also serve as a valuable tool for operator training and system familiarization, providing clear insight into unit design and operation.
Clients are provided access to the 3D models, allowing them to view and manipulate the equipment from their own office or facility. This capability enables operations and maintenance personnel to virtually inspect the unit, plan maintenance activities, and understand internal components—without draining the tank or interrupting operation.
