The horizontal screw decanter centrifuge (commonly referred to as a "decanter centrifuge") is a highly efficient, continuous solid-liquid separation device widely used in municipal wastewater treatment, industrial effluent processing, and sludge dewatering applications. It utilizes high-speed rotation to generate centrifugal forces (typically 2,000–4,000 times gravity) to rapidly separate solids from liquids in suspensions.

| Parameter | Range / Specification | Description |
|---|---|---|
| Bowl Speed | 1,500–4,000 RPM | Higher speed increases centrifugal force and separation efficiency |
| Length-to-Diameter Ratio | 3:1 to 4:1 | Larger ratio = longer residence time; suitable for fine particles |
| Differential Speed | 5–50 RPM | Speed difference between bowl and scroll; critical for cake transport |
| Separation Factor | 2,000–4,000 × g | Determines separation sharpness and liquid clarity |
| Solid Recovery Rate | >95% | Enhanced by BD plate (beach discharge) technology |
| Cake Moisture Content | 70%–80% | Reduces sludge moisture from ~99% down to 70–80% |
The horizontal screw decanter centrifuge operates on the principle of centrifugal sedimentation:
