RDT
Rotating Drum Thickener
The Rotating Drum Thickener (RDT) is an innovative ‘sludge thickening’ system that improves the dewatering capabilities of slurries/sludges with low solids concentration, typically 0.35%DS to >1%DS.
The RDT uses the principal of gravity drainage through a porous filter fabric. Feed slurry is conditioned with polymer through a mixer and flocculator before entry into the drum. Water is sprayed from the spray bar nozzles, continuously cleaning the filter fabric to prevent it from ‘blinding’. Positive displacement of the feed slurry, created by a spiral flight, moves the slurry across the filter fabric. Slurry is turned and rolled as it travels along the drum removing free liquid and increasing solids concentration.
Highlights
- The rotating drum thickener concentrates dilute slurries for volume reduction and solids concentration ahead of dewatering equipment or off-site disposal.
- Its simple, slow-moving design captures solids and converts them into thickened sludge.
- It is intentionally designed for integration with the V-FOLD belt press, but can also be used as a stand-alone process.
- Suitable for municipal and industrial applications, often applied after lamella clarifiers, biological treatment, and dissolved air flotation.
