Rotary Disc Sludge Thickener
The Cost-Effective Way to Boost Your Dewatering Press Performance.
- List Item #1.Compact Footprint: Handles large volumes in a small area.
- List Item #2.Low Speed Operation: < 2.0 RPM minimizes energy use and polymer consumption.
- List Item #3.High Thickening Ratio: Increases solid content from 0.5% to 5% DS.
Directly feeding low-concentration sludge (e.g., 0.5% DS) into a dewatering press is highly inefficient. It overloads the press, reduces final cake dryness, and wastes huge amounts of expensive polymer. The entire sludge line operates at low capacity and high cost.
Our Disc Sludge Thickener acts as a low-cost “booster” stage. It uses a slowly rotating filter disc to gently remove free water, raising the solid content to 2-6% DS. This pre-thickened sludge allows your main dewatering press (Screw Press or Volute) to operate at peak efficiency, doubling its throughput.
| Technical Specs | Performance Standard |
|---|---|
| Inlet Consistency | 0.3% – 1.5% DS |
| Outlet Consistency | Up to 6.0% DS |
| Hydraulic Load | Up to 150 m³/h |
| Material | Full SUS304 / SUS316L |
Q1: Is a thickener always necessary before a dewatering press?
A: For sludge with solid content below 1.5%, a thickener is highly recommended. It can double your dewatering capacity and significantly cut polymer costs, leading to a quick return on investment (ROI) in less than 12 months.
Q2: How is it different from a belt thickener?
A: The Feiran EP Disc Thickener is fully enclosed (odor-free), requires less floor space, and consumes minimal wash water. Belt thickeners often create aerosol mists and require high-pressure washing.
Q3: What kind of filter cloth does it use?
A: It uses a durable polyester woven filter cloth mounted on segmented discs. These segments are easy to replace individually, lowering maintenance costs.
