CentrifugeA centrifuge is a device, which employs a high rotational speed to separate components of different densities. The principle of a centrifuge is based via buoyancy. A component with a higher density would fall to the bottom of a mixture, while the less dense component would be suspended above it. Centrifuges typically produce between 25% and 35% solids by weight.

The main benefit of the centrifuge is the speed of the process. This process is generally reserved for situations where oil recovery is the main priority, and the quality of residual solids is less of a concern.

Centrifuge is most useful for the following applications:

  • Oily Sludge Dewatering
  • Water and Wastewater Treatment Sludge Dewatering

Advantages of Centrifuge

  • Lower maintenance and operation costs
  • Reduced processing time
  • Fast commissioning and start-up
  • Higher throughput capacity
  • Maintenance repair can be done easily, as items can be easily removed and replaced.
  • Centrifuges are easy to clean
  • While centrifuges require an experienced operator to run them, they require minimal operator attention when operations are stable
  • Centrifuges provide low exposure to aerosols, pathogens, hydrogen sulfide, and other odors because of their closed-loop capabilities.
  • Handles oily material

When deciding if a centrifuge is right for your sludge dewatering project, it is important to consider the overall objective, disposal options, and cost of dewatering when deciding which the best choice for your specific needs is.

At Handex we provide our clients support in making these decisions by utilizing our highly experienced dewatering professionals and bench-scale treatability capabilities in evaluating a variety of technologies to choose the optimal solution.
