Unit of Competency NWPTRT014 - Operate and control iron and manganese removal processes
Description
Employability Skills
Learning Outcomes and Application This unit describes the skills required to operate and control iron and manganese removal processes. The ability to identify faults, apply basic process adjustments, according to instructions, and report on the process is essential to performance.This unit applies to those working as operational staff in 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 under supervision, performing routine tasks, within 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 will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace, the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice.

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

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. The candidate must be assessed in at least one of the processes listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on least one occasion.

identifying and reporting faults

completing logs

preparing and applying chemical dosing

monitoring test results and processes

conducting routine process inspections

taking samples and performing basic tests including at least either jar testing or iron and manganese analyses

applying basic process formulae including at least either chemical dosage or detention time

making basic process adjustments according to instructions including at least one of:

dosage

flow rate

detention time
