Elements and Performance Criteria

1. Identify the sources and quality of water available to food processing plants
   • Current and possible future sources and quality of raw water are identified
   • The water quality requirements for required food processing operations are identified
   • The suitability of water supplied from a range of sources, including water recycled from the food processing plant, is assessed
   • The consumption of non recycled water is assessed and a reduction strategy formulated
2. Identify raw water pre treatment processes
   • The steps involved in water purification are documented and data on quality for supplied water is obtained
   • Water disinfection methods and equipment for a range of food processing operations are identified and evaluated
3. Apply efficient and sustainable water management principles to the food processing industry
   • Opportunities for reducing water usage in the food processing operation is identified
   • Sources and characteristics of waste water generated across the food processing operation are identified
   • Methods for treating and recycling water for re-use in food processing operation are identified
   • Opportunities to reduce the volume of waste water and improve treatment methods are identified
   • Procedures for future water management are reviewed and critical limits set

Required Skills

Evidence Required

The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to implement and review water and waste procedures for a food processing operation
Critical aspects for assessment and evidence required to demonstrate competency in this unit	Critical aspects of assessment must include evidence of the ability to assess water quality for use in food processing monitor water usage for a food processing operation integrate water quality monitoring into process planning and implement and review water management procedures in food processing
Context of and specific resources for assessment	Assessment of performance requirements in this unit should be undertaken within the context of food technology Competency is demonstrated by performance of all stated criteria including the critical aspects and knowledge and skills elaborated in the Evidence Guide and within the scope as defined by the Range Statements applicable to the workplace environment Assessment must occur in a real or simulated workplace where the assessee has access to production process and related equipment manufacturers advice and operating procedures methods and related software systems as required for collecting data and calculating yields efficiencies and material variances appropriate to production environment tests used to report relevant productprocess information and recorded results
Method of assessment	The following assessment methods are suggested observation of candidate conducting a range of tests and procedures written andor oral questioning to assess knowledge and understanding completing workplace documentation third party reports from experienced practitioner case studies field Reports
Guidance information for assessment	Evidence should be gathered over a period of time in a range of actual or simulated environments

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Legislation	Legislation refers to any relevant Commonwealth and State Acts of Parliament, Statutes and Regulations including legislation and regulations covering: the use of water for commercial and industrial use environmental protection waste generation and disposal food standards and food safety occupational health and safety.
Policies and procedures	Codes of practice, e.g. Manual Handling and Small Wastewater Treatment Plants Australian and international standards e.g. ISO14000.
Water sources	Water sources may include: reticulated supply from water authorities municipal treatment plants bores dams rainwater tanks recycled water.
Water quality requirements	Water quality requirements for food processing operations may include chemical, microbiological, physical and radiological specifications.
Treatment and disposal methods	Treatment and disposal may include on site storage and disposal; dilution; specifying/controlling discharge rates; recycle and reuse options; on site pre-treatment.
Waste management documentation	Waste management documentation may include information on applicable trade waste laws or other requirements; complaint records; training records; process information, process operation log book; inspection, maintenance and calibration records; relevant contractor and supplier information; incident reports. Information on emergency preparedness and response, records of significant trade waste impacts; audit results; management reviews; trade waste charging policy; industrial trade waste generators register.
