Unit of Competency NWPTRT045 - Assess and improve desalination processes
Description
Employability Skills
Learning Outcomes and Application This unit describes the skills required to assess, evaluate system performance, investigate and report on the optimisation of desalination processes for water treatment and water recycling.This unit applies to those working as water treatment operators responsible for water quality in a range of technical and process applications in water and wastewater treatment.The skills and knowledge described in this unit must be applied within the legislative, regulatory and policy environment in which they are carried out. Organisational policies and procedures must be consulted and adhered to. Those undertaking this unit would work autonomously performing sophisticated tasks in a familiar context.No licensing, legislative or certification requirements apply to unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency should be assessed in an actual workplace or in a simulated environment, with access to equipment and infrastructure appropriate to the outcome. Competency should be demonstrated over time to ensure the candidate is assessed across a variety of situations.

Some components of this unit require assessment in a workplace environment therefore the unit is not suitable for fully external or electronic based assessment.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
