Comparison criteria
Criterion 1
Farm system and water depth
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 2
Biomass and oxygen demand
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 3
Aeration method and placement
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 4
Power consumption
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 5
Emergency redundancy
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 6
Maintenance requirements
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
Criterion 7
Verified local or international availability
Check the manufacturer’s verified specification, the actual farm operating condition and the consequence if this factor is inadequate. Treat missing information as unknown rather than assuming a favourable value.
