- Increased underflow density
- Lower flocculant dose
- Better slimes management
Optimised for performance and operating cost
High-rate Thickeners are designed to provide roughly 12 times the throughput of conventional machines of similar size. The key features for high-capacity thickeners are the feedwell design and the feed slurry dilution method. Our patented E-Volute™ feedwell offers Computational Fluid Dynamics (CFD)- optimised energy dissipation and solids distribution. E-DUC® and P-DUC feed-dilution systems maximise flocculation efficiency and settling rates.
What we offer
Decades of experience in flocculation, feed dilution, and sedimentation technology from EIMCO® and Dorr-Oliver®.
We work with you to address your specific process challenges that affect your thickener selection.
EIMCO and Dorr-Oliver thickeners are available in both bridge-supported and column-supported designs. We offer beam- or truss-type bridges, depending on thickener diameter. In the bridge-supported design, suitable for thickeners up to 50 m in diameter, the drive is supported by the bridge, driving the rakes with a centre shaft.
Column-supported design drives are supported by a stationary centre column of steel or concrete, and are practical for thickeners up to 135 m in diameter. The centre column supports the drive, rake cage and rake mechanisms, while the truss bridge, extending from the centre pier to the tank periphery, supports the walkway and feed system.
Optional lifting devices for either design offer additional operational flexibility.
