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 membrane filtration 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. 1.3 Select, fit and use required safety equipment, including personal protective equipment. |
2. Control chemical use | 2.1 Use, handle and store chemicals. 2.2 Determine chemical dosing. 2.3 Maintain chemical supply and usage records. |
3. Operate and control membrane filtration process | 3.1 Carry out routine plant inspections. 3.2 Conduct and analyse process tests and determine performance against plant operational requirements. 3.3 Make integrated process adjustments to improve system performance. |
4. Complete documentation | 4.1 Collect and record 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.
identifying and correcting operational problems
producing reports and logs
performing system calculations
identifying control system faults
monitoring test results and processes
identifying and reporting faults
taking samples and performing basic tests
making basic process adjustments, including at least one of:
pH correction
backwash frequency
clean in place cycles
collecting data and 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
system processes
lockout procedures for mechanical and electrical installations
hazardous materials handling
risk factors and potential hazards involved with membrane filtration processes
interpretation of safety data sheets
equipment operation, capacity and limitations
pumping and valving systems
mechanical and electrical control systems
principles that form the basis of membrane filtration processes for water or wastewater treatment
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.
