Unit Descriptor

Unit descriptor	This unit of competency involves the knowledge, processes and techniques necessary to select, plan or design a system or facility using high technology water treatment components. Licensing, legislative, regulatory or certification requirements may apply to this unit. Therefore it will be necessary to check with the relevant state or territory regulators for current licensing, legislative or regulatory requirements before undertaking this unit.

Application of the Unit

Application of the unit	This unit addresses the selection, planning or design of a system or facility using high technology water treatment components, such as biological, mechanical/physical/solid and chemical filters. It covers the modification of plans or designs to suit changing circumstances. Activities involving construction or installation of systems or facility, and fish husbandry and handling are covered by other aquaculture, seafood processing and seafood sales and distribution units of competency. These components can be applied within an aquaculture or holding facility in the seafood industry, or an aquascape or holding tank in the ornamental or pet sector. The unit includes the development of work procedures and other techniques to select and use these components. Processes will ensure the ability to recognise when external expertise is needed, and access specialists, technicians and tradespeople as required. The unit will be relevant to those supervisors or managers who have responsibility for a specific facility or who lead a site work group or team. All enterprise or workplace procedures and activities are carried out according to relevant government regulations, licensing and other compliance requirements, including occupational health and safety (OHS) guidelines and ecologically sustainable development (ESD) principles. Equipment operation, maintenance, repairs and calibrations are undertaken in a safe manner that conforms to manufacturer instructions. Appropriate personal protective equipment (PPE) is selected, checked, used and maintained.
