This unit of competency defines the skills and knowledge required to treat and purify metal finishing effluent waters which typically contain cyanides, hexavalent chromium, heavy metal cations, certain anions and greases using appropriate pre-determined waste treatment processes.

Where the interpretation of technical drawings is required unit MEM09002 Interpret technical drawing should also be selected.

Where the selection and use of engineering measurement is required unit MEM12023 Perform engineering measurements should also be selected.

Where the selection and use of tools is required unit MEM18001 Use hand tools and unit MEM18002 Use power tools/hand held operations, should also be selected as appropriate.

No licensing, legislative or certification requirements apply to this unit at the time of publication.

(add new lines for each of the assessment tasks)

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, accessibility of the item, and local industry and regional contexts) are included.
Waste/effluent includes one (1) or more of the following:	rinse waters spent solutions spills leaks
Recording devices include one (1) or more of the following:	pH meter oxidising/reduction/potential probes (redox) flow rate
Waste treatment processes include one (1) or more of the following:	chemical treatments neutralisation metal precipitation solid separation (gravity, centrifuging) oxidation reduction grease entrapment ion exchange reverse osmosis gas scrubbing
Process parameters include one (1) or more of the following:	solution flow pH redox (oxidising /reduction/potential) which typically contain cyanides, hexavalent chromium, heavy metal cations, certain anions and greases

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
