Description
This unit describes the skills required to identify microorganisms and assess the appropriate drinking water or water re-use treatment processes for inactivation or removal.This unit applies to those working as water treatment operators responsible for water quality in a range of technical and process applications in water and wastewater 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 autonomously performing sophisticated tasks in a familiar context.No licensing, legislative or certification requirements apply to unit at the time of publication.
Notes
Elements and Performance Criteria
1. Assess performance of processes to remove microorganisms
  • 1.1 Review existing process performance data.
  • 1.2 Review existing operational processes with reference to manufacturer and plant designer specifications.
  • 1.3 Identify the impact of raw water quality on water treatment effectiveness for microorganism removal.
  • 1.4 Review existing fault reports and other relevant plant asset information.
  • 1.5 Investigate the operational status of plant components.
  • 1.6 Investigate the cause of treated water quality issues relating to microorganisms.
  • 1.7 Assess the effectiveness of process control strategies for microorganism removal.
2. Improve process performance for removal of microorganisms
  • 2.1 Identify treatment process conditions for optimising microorganism removal.
  • 2.2 Determine plant configuration and revised operational processes for process optimisation.
  • 2.3 Plan a trial to test the performance of the determined optimisation options.
3. Report on system performance and improvement
  • 3.1 Report on the current operational status of the water treatment process.
  • 3.2 Report on effective treatment processes and associated sampling and testing procedures to maintain water quality.
  • 3.3 Compile a report making recommendations on optimisation options.
