Range Statement
The range statement indicates the context for demonstrating competence. This statement is a guide and unless otherwise indicated, items may or may not apply as required by the work context.
Work is carried out in accordance with company policies and procedures, manufacturer's recommendations, legislative requirements, site licenses and trade waste service agreements and industrial awards and agreements. Legislation refers to environmental acts and regulations
Workplace information can include Standard Operating Procedures (SOPs) and manufacturer's specifications
Equipment may include screens, ph correction, oil/grease skimmers, settling and treatment ponds, aeration units, lagoons, first flush systems and wetlands, pumps and valves
Confirming equipment status involves conducting relevant pre-start checks, confirming that cleaning and calibration standards are met, all safety guards are in place and equipment is operational
Operation and monitoring of equipment and processes may require the use of control panels and systems
Typical tests may include pH, solids, colour/turbidity, flow rate, settling rate, settled volume, DO and BOD/COD levels
