Techniques

Chapter 1: Techniques

Decanter Centrifuges: The Heart of the Niro Legacy

Niro's name is synonymous with high-performance decanter centrifuges, machines that utilize centrifugal force to separate solids from liquids. This technique, pioneered by Niro Atomizer and now carried forward by Centrico, Inc., is crucial in numerous environmental and water treatment applications.

How Decanter Centrifuges Work:

  • Centrifugal Force: The core principle is the application of centrifugal force, which spins the feed mixture at high speeds. This force pushes denser solids towards the outer wall of the centrifuge bowl.
  • Differing Densities: The heavier solids are pushed outwards, forming a compacted layer against the bowl wall. The lighter liquid is directed towards the center of the bowl.
  • Screw Conveyor: A screw conveyor, running along the length of the bowl, moves the compacted solids out of the centrifuge, while the clarified liquid exits through a separate discharge port.

Advantages of Decanter Centrifuges:

  • High Efficiency: Decanters are highly efficient in separating solids from liquids, even in challenging conditions.
  • Large Processing Capacity: They can handle substantial volumes of material, making them suitable for industrial-scale applications.
