List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
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. Monitor sedimentation and clarification plant performance | 1.1 Monitor test results and processes to maintain the parameters of operation. 1.2 Identify and report process faults and the operational condition of plant. |
2. Control chemical use | 2.1 Use, handle and store chemicals. 2.2 Prepare and apply chemical dosing. 2.3 Maintain chemical supply and usage records. |
3. Operate and control sedimentation and clarification processes | 3.1 Carry out routine plant inspections. 3.2 Collect process samples and conduct standard tests. 3.3 Perform process calculations associated with sedimentation and clarification processes. 3.4 Carry out system adjustments to enhance system performance. |
4. Complete documentation | 4.1 Collect and report process data. 4.2 Report observations outside defined parameters for further action. |
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.
producing reports and logs
performing process calculations
preparing and applying chemical dosing
identifying control system faults
sampling and testing products
conducting routine plant inspections
taking samples and performing basic tests
making basic system adjustments
completing required documentation
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.
system layout
lockout procedures for mechanical and electrical installations
relevant utilities and service bodies
settling aids
theory of enhanced particle settling including chemical and physical processes
hazardous materials handling
environment, landscape and ground structure of work area
risk factors and potential hazards relating to water and/or wastewater treatment
chemical dosing processes
equipment operation, capacity and limitations
effects of weather and conditions on operation of site or plant
pumping and valving systems
control systems’ policies and procedures for storing and handling dangerous goods and chemicals
SDS
coagulation/flocculation theory and operation
chemical and/or biological principles that form the basis of sedimentation and clarification processes
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.
