Sludge Thickener
Thickeners are similar to other circular clarifiers in appearance and operation, but typically require higher operating torque and alternate sludge collection designs for optimal performance.
Applications
- Sludge thickening in municipal and industrial wastewater treatment plants.
- Mining and mineral processing to thicken tailings, concentrate ores, and recover process water.
- Chemical and pharmaceutical industries for solids–liquid separation and slurry concentration.
- Food and beverage processing for thickening organic slurries.
- Power plants for ash slurry thickening and water recovery.
- Paper and pulp industries to increase solids concentration before dewatering.
- Pre-dewatering step before filter presses, centrifuges, or belt presses.
Key Features & Benefits
- High-torque drive mechanism designed to handle dense, heavy sludge loads.
- Robust sludge collection system such as picket fences, rakes, or rotating arms optimized for thickening applications.
- Deep, wide settling zone allowing more time and surface area for solids compaction.
- Low overflow rates ensuring clearer supernatant discharge.
- Automatic sludge withdrawal control for consistent underflow concentration.
- Minimal maintenance requirements due to slow-moving and sturdy components.
- Customizable design including tank diameter, rake type, and drive capacity.
- Energy-efficient operation with slow rotational speeds and durable mechanical parts.
