Unit of Competency NWPTRT031 - Operate and control sedimentation and clarification processes
Description
Employability Skills
Learning Outcomes and Application This unit of competency describes the outcomes required to monitor, operate and control sedimentation and clarification plant; and to measure and report on system performance and process quality control. The ability to identify faults, determine and apply technical adjustments, conduct chemical dosing procedures and produce technical reports are essential to performance.This unit supports the attainment of skills and knowledge required for operational staff with a specific responsibility for sediment and clarification processes in water treatment plants.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, particularly those relating to safety.Those undertaking this unit would work under supervision, while performing routine tasks, within a range of familiar contexts.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.
