Sedimentation

PE&C can enhance your stand-alone thickener or CCD circuit by reviewing and benchmarking key design and performance parameters. Areas assessed typically include:

  • Slurry feed systems
  • Flocculant selection, make-up and dosing
  • Rake design and rake drive features
  • Key instrumentation and control systems

A counter-current decanter (CCD) is crucial for red mud washing in alumina refineries and is also used in hydrometallurgical processes. By analyzing and optimizing your CCD circuit, PE&C helps improve performance metrics like condensate and caustic liquor consumption.
