Knowledge of: Purpose and basic principles of membrane processing. This includes an understanding of the components of milk, particle size of each component and the effect on these components of membrane processing. It also includes an understanding of the methods used to achieve this outcome Basic operating principles of equipment. This may include an operational understanding of main equipment components, status and purpose of guards, equipment operating capacities and applications, and the purpose and location of sensors and related feedback instrumentation. It also includes an awareness of the material composition of membranes used in the workplace and related operating, cleaning and storage requirements The flow of the membrane process including the different processing streams and the effect of the membrane process outputs on downstream processes Quality characteristics required of the membrane processing outputs The effect of variation in raw material characteristics on membrane processing performance Operating requirements and parameters and corrective action required where operation is outside specified operating parameters. This includes an understanding of the effect of variation in processing parameters such as temperature, pressure, total solids and flow rates on membrane process performance Typical equipment faults and related causes. This includes recognition of signs and symptoms of faulty equipment and early warning signs of potential problems Techniques used to monitor membrane processing. This may include inspecting, measuring and testing as required by the process. It requires awareness of inspection or test points (control points) in the process and the related procedures and recording requirements Contamination/food safety risks associated with the process and related control measures Common causes of variation and corrective action required OHS hazards and controls. This includes awareness of the limitations of protective clothing and equipment relevant to the work process Requirements of different shutdowns as appropriate to membrane processing and workplace production requirements. This includes emergency and routine shutdowns and procedures to follow in the event of a power outage and shutdown Cleaning and sanitation requirements associated with changeovers Isolation, lock out and tag out procedures and responsibilities Procedures and responsibility for reporting production and performance information Environmental issues and controls relevant to membrane processing. This includes waste collection and handling procedures related to the process Basic operating principles of process control where relevant. This includes the relationship between control panels and systems and the physical equipment Routine maintenance procedures where relevant Sampling and testing associated with process monitoring and control where relevant |
