Operate a biotreater

Formats and tools

Unit Description
Reconstruct the unit from the xml and display it as an HTML page.
Assessment Tool
an assessor resource that builds a framework for writing an assessment tool
Assessment Template
generate a spreadsheet for marking this unit in a classroom environment. Put student names in the top row and check them off as they demonstrate competenece for each of the unit's elements and performance criteria.
Assessment Matrix
a slightly different format than the assessment template. A spreadsheet with unit names, elements and performance criteria in separate columns. Put assessment names in column headings to track which performance criteria each one covers. Good for ensuring that you've covered every one of the performance criteria with your assessment instrument (all assessement tools together).
Wiki Markup
mark up the unit in a wiki markup codes, ready to copy and paste into a wiki page. The output will work in most wikis but is designed to work particularly well as a Wikiversity learning project.
Evidence Guide
create an evidence guide for workplace assessment and RPL applicants
Competency Mapping Template
Unit of Competency Mapping – Information for Teachers/Assessors – Information for Learners. A template for developing assessments for a unit, which will help you to create valid, fair and reliable assessments for the unit, ready to give to trainers and students
Observation Checklist
create an observation checklist for workplace assessment and RPL applicants. This is similar to the evidence guide above, but a little shorter and friendlier on your printer. You will also need to create a seperate Assessor Marking Guide for guidelines on gathering evidence and a list of key points for each activity observed using the unit's range statement, required skills and evidence required (see the unit's html page for details)

Self Assessment Survey
A form for students to assess thier current skill levels against each of the unit's performance criteria. Cut and paste into a web document or print and distribute in hard copy.
Moodle Outcomes
Create a csv file of the unit's performance criteria to import into a moodle course as outcomes, ready to associate with each of your assignments. Here's a quick 'how to' for importing these into moodle 2.x
Registered Training Organisations

Reference books for 'Operate a biotreater' on fishpond.com.au. This online store has a huge range of books, pretty reasonable prices, free delivery in Australia *and* they give a small commission to ntisthis.com for every purchase, so go nuts :)

Elements and Performance Criteria



1. Monitor and control the biotreater processes

1.1. Get information relevant to the operation of the biotreater

1.2. Identify changes in key variables

1.3. Keep feed as consistent as possible

1.4. Check performance of ancillaries such as agitation

1.5. Recognise and interpret trends in biotreater data/appearance

1.6. Recognise the signs of potential and actual problems

1.7. Identify the consequences to the biotreater processes of the identified changes, trends and problems

1.8. Take appropriate action to minimise the impact of potential and actual problems.

2. Ramp performance up/down.

2.1. Anticipate significant changes in feed

2.2. Breed up/down biomass to prepare for change in feed by changing variables

2.3. Ramp changed feed at a rate suitable for the biotreater

2.4. Establish stable operation for new feed conditions.

3. Maintain effectiveness of biotreater system.

3.1. Frequently and critically monitor biotreater system throughout shift

3.2. Use measured/indicated data and smell, sight, sound and feel as appropriate

3.3. Identify critical equipment and processes

3.4. Identify issues likely to impact on the whole plant performance and take appropriate action

3.5. Predict impact of a change in the biotreater system on other plant units/areas and communicate this to relevant people

3.6. Predict impact of a change in the processing plant on the biotreater and take appropriate action

3.7. Test trips and alarms as required in liaison with the panel operator.

4. Manage impact of shutdowns on biotreater system.

4.1. Identify type of shutdown required/occurring

4.2. Identify impact of type of shutdown on biotreater

4.3. Liaise with appropriate people for shutdown

4.4. Arrange to maintain adequate feed to biotreater for a short plant shutdown

4.5. Arrange to preserve adequate seed stock of micro-organisms for long plant shutdown or shutdown of biotreater

5. Isolate and de-isolate biotreater.

5.1. Isolate biotreater or biotreater components

5.2. Make safe for required work

5.3. Check plant is ready to be returned to service

5.4. Prepare biotreater or plant component for return to service

5.5. Ramp biotreater back to normal operation..

6. Control hazards.

6.1. Identify hazards in biotreater work area

6.2. Assess the risks arising from those hazards

6.3. Implement measures to control those risks in line with procedures and duty of care.
