OTE tests allow plant owners to assess the long term running costs of their aeration systems, and confirm that they have the capacity to meet peak oxygen demands. Due to this, utilities will often require on OTE report prior to handover of a new treatment plant, to ensure it meets specification.

Mixing efficiency testing provides valuable information actual residence times and mixing characteristics in a tank/mixing system. Testing can be conducted on new or redesigned mixing systems, or where there has been a change to the process or flow rate through the tank. On older tanks where there may be large solids deposition, it can provide important information on active volume.  Testing is usually conducted for 2 or 3 times the hydraulic retention time of the tank under test.
