In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
Learners who demonstrate competence as described in the outcomes of this unit standard will be able to understand solid-vapour and surface-based separation equipment in a processing environment.

The qualifying learner is able to:
  • Demonstrate an understanding of crystallisation in process applications.
  • Demonstrate an understanding of dryers in process applications.
  • Demonstrate an understanding of membrane based separation process applications.
  • Demonstrate an understanding of surface based separation process applications.

    This will ensure that separation equipment in a processing environment is used in accordance with procedures and accepted work practices. This competence will enhance the learner's employability and career options in all occupations where knowledge of separation equipment in a process environment is needed. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    Description of required skills:
  • National Certificate Chemical Operations NQF Level 2 or equivalent, including communication and mathematical literacy, NQF Level 2. 

  • UNIT STANDARD RANGE 
    The context of this unit standard includes a complete process, from the point of receiving a commodity raw material to the point of supplying a commercially saleable product.

    The level assigned to this unit standard is appropriate because the process requires a wide range of cognitive skills and offers a considerable choice of solutions. A broad knowledge base incorporating some theoretical concepts, analytical interpretation of information, informed judgement and a range of sometime innovative responses to concrete but often unfamiliar problems are employed.

    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.
