Unit of competency
Modification History
Release 1. This is the first release of this unit of competency in the NWP National Water Training Package. |
Application
This unit involves the skills and knowledge required to assess and improve granular media filters. It includes evaluating and reporting on system performance and process quality control and may require the control and coordination of granular media filtration processes used in water and wastewater treatment. This unit applies to those working as technical staff with responsibility for optimising granular media filtration processes in water or wastewater treatment plants. This role may include coordination or supervision of a work team, or may be performed by a single operator, depending on the size of the treatment plant. Those undertaking this unit would work autonomously, usually with supervisory responsibilities, while performing complex tasks within a range of familiar contexts. No licensing, legislative or certification requirements apply to this unit at the time of publication. |
