Rotary Drum Thickener - Sludge Thickening Equipment

The Rotary Drum Thickener is an excellent option for many thickening applications. The RDT provides high thickening capacity and performance in a small footprint with minimal water usage and maintenance costs in a naturally enclosed unit.

Features:

  • Variable Drum Speed Drive – Allows control of slurry depth inside the drum maximizing thickening performance
  • Center Shaft / Bearing design – Bearings are all located outside the enclosure, keeping bearings from being exposed to process fluids
  • Enclosure – Fully enclosed with easily accessible points for optimization and maintenance.
  • Dual drum offers built in redundancy on single frame

Recent Improvements:

  • Increased center shaft diameter for durability and longevity
  • Redesigned inlet to reduce polymer usage and increase solids capture
