Elements and Performance Criteria

1. Prepare the mud filtration process for operation
   • Mud is assessed and conditioned to meet filtration requirements
   • Services are confirmed as available and ready for operation
   • Equipment is checked to confirm readiness for use
   • The mud filtration process is set to meet production requirements
2. Operate and monitor the mud filtration process
   • The mud filtration process is started up and operated according to company procedures
   • Control points are monitored to confirm performance is maintained within specification
   • Mud meets specification for pol and moisture
   • Equipment is monitored to confirm operating condition
   • Out-of-specification mud, process and equipment performance is identified, rectified and/or reported according to workplace reporting procedure
   • The workplace meets housekeeping standards
3. Handover the mud filtration process
   • Workplace records are maintained in accordance with workplace procedures
   • Handover is carried out according to workplace procedure
   • Mud filtration operators are aware of system and related equipment status at completion of handover
4. Shut down the mud filtration process
   • The appropriate shut down procedure is identified
   • The mud filtration system is shut down according to workplace procedures
   • The mud filtration system is prepared for storage in shut down mode
   • Maintenance requirements are identified and reported according to workplace reporting procedure

Required Skills

Not applicable

Evidence Required

The assessment process must address all of the following items of evidence

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, codes of practice and industrial awards and agreements. Codes of practice include the Sugar Milling Operations Industry Code of Practice

Workplace information can include Standard Operating Procedures (SOPs), specifications, production schedules and manufacturer's specifications

Mud filtration equipment may include clarifier mud removal, mud tank/mud mixer, bagacillo system, filtrate receivers and pump, vacuum pumps, mud filter, mud conveying system and storage, filter wash water supply, lime, flocculant and filtrate recycle to mud system

Confirming equipment status involves conducting relevant pre-start checks, confirming that cleaning standards are met, all safety guards are in place and equipment is operational. It may also involve checking operation/calibration of measuring instrumentation

Operation and monitoring of equipment and processes typically requires the use of control panels and systems

Services may include power, water, compressed and instrumentation air

Materials can include lime, flocculants, saccharate and preservatives

Where tests are conducted as part of operation, typical requirements are for pH and thymol testing

Monitoring the process may involve the use of production data such as performance control charts

Control points refer to those key points in a work process which must be monitored and controlled

Work may require the ability to work within a team environment

Information systems may be print or screen based
