2Operate and control RO and/or NF processes. | 2.1 Carry out routine plant inspections according to organisational and plant requirements. 2.2 Conduct and analyse process tests and compare performance to plant operational requirements. 2.3 Make integrated process adjustments to optimise system performance according to organisational and statutory requirements. 2.4 Collect, interpret and record process according to organisational and plant requirements. 2.5 Correctly select, fit and use required safety equipment, including personal protective equipment. |
3Compile process reports. | 3.1 Compile reports from plant and system data to meet organisational procedures and statutory requirements. 3.2 Report observations outside defined parameters for further action. |
Required Skills
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: solve operational problems produce reports and logs use safety and personal protective equipment interpret plans, charts and instructions interpret policies, procedures and standards communicate with employees and customers use communication equipment give and receive instructions determine chemical dosing requirements perform system calculations operate control equipment identify control system faults perform system calculations collect samples and perform tests. |
Required knowledge: system layout system processes lock out procedures for mechanical and electrical installations policies, procedures and legislation relevant utilities and service bodies communication systems hazardous materials handling interpretation of material safety data sheets principles that form the basis of reverse osmosis and nano-filtration processes risk factors and potential hazards equipment operation, capacity and limitations pipes and fittings pumping and valving systems mechanical and electrical control systems. |
Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the Performance Criteria, Required Skills and Knowledge, the Range Statement and the Assessment Guidelines for the Training Package. | |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The candidate should demonstrate the ability to monitor, operate and control reverse osmosis and nano-filtration processes, including: monitoring test results and processes identifying and reporting faults conducting routine plant inspections taking samples and performing basic tests making basic process adjustments according to instructions collecting data and completing required documentation. |
Context of and specific resources for assessment | Access to the workplace and resources including: documentation that should normally be available in a water industry organisation relevant codes, standards and government regulations. Where applicable, physical resources should include equipment modified for people with disabilities. Access must be provided to appropriate learning and/or assessment support when required. Assessment processes and techniques must be culturally appropriate, and appropriate to the language and literacy capacity of the candidate and the work being performed. Validity and sufficiency of evidence requires that: competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace where the assessment is part of a structured learning experience the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice a decision of competence only taken at the point when the assessor has complete confidence in the person's competence over time and in various contexts all assessment that is part of a structured learning experience must include a combination of direct, indirect and supplementary evidence where assessment is for the purpose of recognition (RCC/RPL), the evidence provided will need to be authenticated and show that it represents competency demonstrated over a period of time assessment can be through simulated project-based activity and must include evidence relating to each of the elements in this unit. Questioning will be undertaken in a manner appropriate to the skill levels of the operator, any cultural issues that may affect responses to the questions, and reflecting the requirements of the competency and the work being performed. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the Performance Criteria, is detailed below. Add any essential operating conditions that may be present with training and assessment depending on the work situation, needs if the candidate, accessibility of the item, and local industry and regional contexts. | |
