What is Decanter Centrifuge?

Selecting the right decanter centrifuge is critical to achieving reliable, efficient, and long-term solid-liquid separation in industrial processes. From mining and hydrometallurgy to wastewater treatment and chemical manufacturing, centrifuges are often the backbone of process performance.

A decanter centrifuge continuously separates solids from liquids by using centrifugal force. Inside the rotating bowl, denser solids settle outward while lighter liquid phases form inner layers. The scroll conveyor (or screw) transports the solids to the discharge end, while clarified liquid exits through adjustable weirs.

The scroll conveyor (or screw) transports the solids to the discharge end, while clarified liquid exits through adjustable weirs.

In hydrometallurgical and chemical industries, decanters are used for:

  • Two-phase (solid-liquid) or three-phase (solid-liquid-liquid) separation
  • Dewatering and thickening of slurries
  • Clarification and fine solids classification

In every Wastewater Treatment Plant (WWTP), the sludge dewatering stage is critical to reduce water content, volume, and disposal cost. The most common machines used are Decanter Centrifuge, Filter Press, Belt Press, and Screw Press. Each technology offers unique strengths depending on sludge characteristics and operational requirements.


Core Function of Sludge Dewatering Machines

All sludge dewatering systems aim to remove excess moisture and increase dry solids (DS%) to minimize handling costs and environmental impacts.

Key benefits:

  • Volume reduction for cheaper transportation.
  • Improved sludge stability.
  • Recovered water suitable for reuse or discharge.
