This document specifies general requirements for the non-steady state measurement of the oxygen transfer rate and the oxygen transfer efficiency of aeration systems in activated sludge aeration tanks (see EN 12255-6) when filled with clean water. This document refers to two TS’s describing different test methods (CEN/TS; 20XX 0-D method and CEN/TS; 20XX 1-D method).
Testing is required as part of conformance evaluation at peak capacity and to establish operating costs at average capacity, unless the operator determines that the test is not required.
NOTE 1 This is known as the clean water test.
