Modification History

Release

Comments

This unit was released in NWP Water Training Package release 1.0 and meets the Standards for Training Packages.

This unit supersedes and is equivalent to NWP406A Investigate and plan the optimisation of granular media filtration processes.

Unit code updated
Content and formatting updated to comply with the new standards
All PC transitioned from passive to active voice
Unit title changed to better reflect unit outcomes
One new PC added to Element 2

Application

This unit describes the skills required to evaluate and report on system performance and process quality control and may require the control and coordination of granular media filtration processes used in water and wastewater treatment.

This unit applies to those working as technical staff with responsibility for optimising granular media filtration processes in water or wastewater treatment plants. This role may include coordination or supervision of a work team, or may be performed by a single operator, depending on the size of the treatment plant.

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, particularly those relating to manufacturers' specifications.

Those undertaking this unit would work under indirect supervision, while performing complex tasks within a range of familiar 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. Assess granular media filtration process performance	1.1 Review existing process performance data. 1.2 Review existing operational processes . 1.3 Identify the impact of incoming water quality on granular media filtration processes. 1.4 Identify any additional sampling and testing required for valid evaluation of current process performance.
2. Investigate granular media filtration plant or equipment operation	2.1 Review existing fault reports and other relevant plant asset information. 2.2 Investigate the operational status of plant components. 2.3 Carry out investigations to identify potential deficiencies.
3. Investigate the operational options for process optimisation	3.1 Review relevant fault and incident reports and remedial actions taken. 3.2 Investigate current media status with reference to manufacturer or plant designer specifications. 3.3 Investigate potential changes to operational processes to identify possible optimisation strategies.
4. Develop and record a plan for process optimisation	4.1 Determine plant configuration or media options and revised operational procedures for process optimisation. 4.2 Plan a trial to test the performance of the determined optimisation options. 4.3 Compile a report making recommendations on optimisation options.

Assessment Requirements created drawing upon specified assessment information from superseded unit

Performance Evidence

Evidence required to demonstrate competence must satisfy all of the requirements of the elements and performance criteria. The candidate must be assessed in as least one type of process listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on at least one occasion.

conducting system investigation and reporting on operational or control system problems
coordinating filter inspection, sampling and testing
conducting trend analysis for long-term filter monitoring
performing calculations to provide data for the analysis and development of options and solutions, including backwash rates and filtration rates
determining filter run and backwash profiles and times
interpreting a range of complex and technical documents, including at least one of:

regulatory, legislative, licensing and organisational requirements
codes and standards
specifications
organisational policies

analysing problems and recommending appropriate remedial solutions
reviewing existing filtration process performance with reference to historical data, initial specifications and differences in incoming water quality
identifying data deficiencies and organising additional data collection through appropriate sampling and testing
assessing faults and incident reports and investigating the status of filtration plant components and media
investigating potential changes to filtration operational processes to identify possible optimisation strategies
planning trials to test the performance of the determined filtration optimisation options
compiling recommendation reports

Knowledge Evidence

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.

principles that form the basis of granular media filtration processes
types of filters and their range of applications, conditions for use and manufacturers’ requirements
backwash principles and optimisation
filter run profiles
the range and performance of filter aids
filter media properties and selection
filter inspection and sampling
principles of filter maintenance, including:

filter cleaning
double backwashes
surface cleaning
lancing
caustic washing

filter ripening and turbidity breakthrough
pilot filters
pumping and valving systems
range of appropriate measuring and testing procedures

Assessment Conditions

Competency will need to be demonstrated over a period of time reflecting the scope of the role and the practical requirements of the workplace, the evidence collected must relate to a number of performances assessed at different points in time and separated by further learning and practice.

Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
