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

Application

This unit describes the skills required to operate and control iron and manganese removal processes. The ability to identify faults, apply basic process adjustments, according to instructions, and report on the process is essential to performance.

This unit applies to those working as operational staff in treatment.

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.

Those undertaking this unit would work under supervision, performing routine tasks, within a familiar context.

No licensing, legislative or certification requirements apply to unit at the time of publication.

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 at least one of the processes listed in the Range of Conditions. If not otherwise specified the candidate must demonstrate evidence of performance of the following on least one occasion.

  • identifying and reporting faults
  • completing logs
  • preparing and applying chemical dosing
  • monitoring test results and processes
  • conducting routine process inspections
  • taking samples and performing basic tests including at least either jar testing or iron and manganese analyses
  • applying basic process formulae including at least either chemical dosage or detention time
  • making basic process adjustments according to instructions including at least one of:
  • dosage
  • flow rate
  • detention time
  • pH

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.

  • chemical forms and occurrence of iron and manganese
  • impact of stratification in reservoirs
  • problems associated with iron and manganese in drinking water systems
  • chemistry of common oxidation removal processes including aeration, chlorination, potassium permanganate
  • manganese coated filtration removal processes including greensand
  • ion exchange removal processes
  • sequestering with polyphosphates
  • chemical dosing processes

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.
