Centrifugal separation control

Centrifugation is a process used for liquid/liquid or liquid/solid separation. There are two main uses of centrifuges in industrial applications: fluid clarification and solids concentration. Centrifuges are used widely across many industries for a wide variety of applications. Examples of applications where centrifuges are used are milk separation, wastewater clarification, [olive] oil degassing and clarification, beer haze removal, solids removal from slurries in the food, oil and chemical industries.

Kemtrak in-line photometers can be placed at a number of locations on a centrifuge in order to:

  • 0.01 NTU – 100% suspended solids (liquid)
  • get a real time continuous measurement
  • optimize centrifuge operation
  • increase product yield / reduce product loss
  • solids concentration
  • increased separation efficiency
  • fluid clarification


The feed stream of a centrifuge will often vary in solids content, adversely effecting the performance. By monitoring changes in the feed concentration using a Kemtrak TC007 LED turbidimeter, overloads can be prevented, bowl speed can be optimized and flow can be controlled based on solids content.

The centrate is a common location used to control and optimize a centrifugal separator and to protect downstream filtration equipment.

The concentrate may also be monitored in order to evaluate the centrate carryover or solids content.

TC007 Product Brochure

The Kemtrak TC007 LED turbidimeter uses a long life NIR LED light source to precisely measure the optical density of turbid liquids for applications such as monitoring the solids concentration in the concentrate. With the TC007 Extreme Suspended solids analyser up to very high suspended solids.

Optic fibers are utilized to pipe the light from within the analyzer enclosure to the sampling point and back. Kemtrak measurement cells are available in a range of materials and design, including DIN, ASME and sanitary TriClamp flanges.
