This unit supports the attainment of skills and knowledge required for operational staff with responsibility for checking that sedimentation processes comply with organisational performance requirements. |
Not applicable.
ELEMENT | PERFORMANCE CRITERIA |
1Plan and prepare for work. | 1.1 Determine work requirements according to legislative and organisational requirements. 1.2 Select and check equipment required to meet safety requirements of task and site. 1.3 Select, fit and use personal protective equipment. |
2Monitor and operate sedimentation processes. | 2.1 Carry out sedimentation process inspections according to type of plant. 2.2 Collect process samples and conduct standard tests. 2.3 Collect and report process data according to organisational and plant requirements. 2.4 Monitor processes to maintain parameters of operation. 2.5 Identify and report process faults and operational condition of plant according to organisational requirements. 2.6 Carry out basic system adjustments to enhance system performance according to organisational requirements. |
3Report sedimentation processes. | 3.1 Compile records from plant and system data to meet organisational requirements. 3.2 Report observations outside defined parameters for further action. |
This describes the essential skills and knowledge and their level, required for this unit. |
Required skills: identify and respond to operational problems produce reports and logs use safety equipment and personal protective equipment follow plans, charts and instructions perform system calculations apply procedures and standards communicate with employees and various customers work effectively as part of a team use communication equipment give and receive instructions identify control system faults use literacy skills in regard to verbal and written communication in the workplace sample and test products. |
Required knowledge: principles that form the basis of sedimentation processes system layout lock-out procedures for mechanical and electrical installations policies, procedures and legislation relating to water treatment communication systems risk factors and potential hazards basic system calculations equipment operation, capacity and limitations effects of changes in hydraulic load on sedimentation processes. |
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 report on sedimentation processes by: planning and conducting routine plant inspections monitoring system processes reporting process and structural faults performing system adjustments completing system performance monitoring 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 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 should only be made 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. In all cases where practical assessment is used it will be combined with targeted questioning to assess the underpinning knowledge. Questioning will be undertaken in a manner appropriate to the skill levels of the operator and cultural issues that may affect responses to the questions, and will reflect the requirements of the competency and the work being performed. |
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 of the candidate, accessibility of the item, and local industry and regional contexts. | |
Legislative and organisational requirements may include: | relevant federal and state or territory legislation and regulations codes of practice, associated standards and guidance material documented organisational policies, manuals and induction programs relevant community planning and development agreements, such as land care agreements. |
Equipment used may include: | electronic monitoring and metering systems recording systems basic hand and power tools sampling and laboratory testing equipment computerised equipment communication equipment personal protective equipment. |
Tests may include: | pH dissolved oxygen settleable solids concentration (cone test) suspended solids temperature total solids concentration. |
Processes may include: | Imhoff tanks conventional clarifiers and sedimentation tanks lamellar thickeners picket fence thickeners gross pollution traps primary treatments, such as primary sedimentation oily water separators riffle plate separators. |
System adjustments may include: | sludge withdrawal rates scum removal inflow control. |
