- pH adjustment (lime, soda ash or caustic)
- generation of chlorine dioxide (sodium chlorite, hydrochloric acid, sodium hypochlorite and/or liquefied chlorine)
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.
- properties and chemistry of chlorine dioxide
- pH
- microbiological water quality guidelines
- chlorine dioxide system layout

Assessment Conditions
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.
Some components of this unit require assessment in a workplace environment therefore the unit is not suitable for fully external or electronic based assessment.
Consideration must be given to holistic assessment for this unit. Refer to advice in the companion volumes.
Assessors must satisfy the NVR/AQTF mandatory competency requirements for assessors.
