Description
This unit involves the skills and knowledge required to assess and improve chemical dosing processes in wastewater.It includes reviewing, facilitating and optimising chemical addition processes and evaluating and reporting on system performance and process quality control.This unit applies to those working as technical staff with a responsibility for optimising chemical addition processes in wastewater treatment. Those undertaking this unit would work autonomously, usually with supervisory responsibilities, while performing complex tasks in a range of contexts.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1 Evaluate chemical addition process performance
  • 1.1 Review existing process performance data against organisational operating protocol
  • 1.2 Identify the impact of changing feed characteristics on chemical addition processes
  • 1.3 Identify any additional sampling and testing required for valid evaluation of current process performance
2 Investigate chemical addition plant configuration
  • 2.1 Assess existing fault reports and other plant asset information
  • 2.2 Investigate the operational status of plant components with reference to manufacturer and plant design specifications
  • 2.3 Contribute to plant configuration investigations to identify potential deficiencies
  • 2.4 Identify hazards, assess risks and control measures according to workplace procedures
3 Investigate chemical options for process optimisation
  • 3.1 Review current chemical addition practices with reference to organisational protocol to identify potential deficiencies
  • 3.2 Investigate dosing options for current chemicals
  • 3.3 Identify and investigate tests to assess effectiveness of existing or alternative chemicals and related dosing options
4 Develop and record a plan for process optimisation
  • 4.1 Determine plant configuration or chemical options for process optimisation
  • 4.2 Plan a trial to test the performance of the determined optimisation options
  • 4.3 Compile report with recommendations on optimisation options
