Oxygen uptake rate measurements for application at wastewater treatment plants
Increasing discharge demands put higher pressure on process optimisation and control of the wastewater treatment plant performance. For evaluation and regulation of the process performance, oxygen uptake rate (OUR) measurement is a useful tool. In this paper one way to perform oxygen uptake rate measurements is described. Possible applications of the method for wastewater treatment plants are presented and associated questions and problems are highlighted. Benefits and drawbacks of the OUR method are discussed. In order to obtain more detailed information about the wastewater, examples of complementary methods to the OUR method are exemplified.
