Application
This unit describes the skills required to identify and apply to water systems and processes the principles of chemistry, and to select the relevant and effective chemicals required for specific processes.
This unit applies to a range of operational roles within the water industry and is fundamental to all quality monitoring and treatment processes.
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 independently while performing complex tasks within a range of contexts.
No licensing, legislative or certification requirements apply to unit at the time of publication.
Elements and Performance Criteria
ELEMENTS | PERFORMANCE CRITERIA |
Elements describe the essential outcomes | Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the range of conditions section. |
1. Apply chemistry to water processes | 1.1 Apply relevant chemistry principles to improve performance of specific water processes. 1.2 Identify and describe chemical reactions specific to water processes. |
2. Identify the use of chemicals in water industry processes | 2.1 Assess the functions of the range of industry chemicals in relation to their use in water processes. 2.2 Identify and describe factors influencing the effectiveness of chemical use. 2.3 Store, handle and prepare chemicals. |
3. Select chemicals for specific water industry processes | 3.1 Identify the range of chemicals available for specific water industry processes. 3.2 Evaluate the factors affecting the selection of chemicals for particular water industry applications. 3.3 Select suitable chemicals and calculate correct usage for a range of specific water industry processes. |
Evidence of Performance
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.
interpreting a range of complex and technical documents including relevant:
regulatory, legislative, licensing and organisational requirements
codes and standards
specifications
organisational policies
analysing and evaluating reports and reference materials
performing various calculations to provide data for the analysis and development of options and solutions
identifying risks and hazards
Evidence of Knowledge
Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. If not otherwise specified the depth of knowledge demonstrated must be appropriate to the job context of the candidate.
standards and workplace policies and procedures determining the use and management of chemical processes
chemical concepts relevant to water industry processes
chemical reactions
range and characteristics of chemicals used in various water industry processes
functions of various chemicals in water industry processes
factors influencing the effectiveness of chemicals
factors affecting the selection of chemicals
Assessment Conditions
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.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
Foundation Skills
