An aerator test rig has been built which is capable of determining the oxygenation capacity of any aeration device in operation in a sewage treatment works. The test rig comprises a tanker vehicle for mixing the required chemicals and a mobile laboratory. The test rig has proved a technical success and been used for five tests during the demonstration phase of the project. The results of these tests show that energy savings of up to 15 % are possible with surface aerators but for diffused air plants savings of only a few percent are possible. The aerator test rig is therefore a commercially viable proposition only in countries which utilise treatment systems with surface aerators such as oxidation ditches.
