120259  Separate liquids using a centrifugal separator  Level 3  NQF Level 03  8   

PURPOSE OF THE UNIT STANDARD 
This Unit Standard is for anyone who has to separate liquids with different densities by means of a centrifugal separator. Centrifugal separation also includes clarification and bactofuging.

A person credited with this unit standard is able to:
  • Demonstrate an understanding of separating liquids using centrifugal force.
  • Prepare to separate liquids with different densities.
  • Separate liquids using centrifugal force.
  • Perform end of separation procedures. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
