Oxygen transfer rate measurement in activated sludge by the gaseous tracer method

Creators

Description

Measurement of the oxygen transfer rate in aeration installations by use of the radioactive gas 85Kr as a tracer for oxygen is described. The method has been introduced in Denmark through several measurements in two different waste water treatment plants. The method showed good reproducibility and represents several advantages compared to conventional methods. The ability of performing the measurement under normal operating conditions is emphasized.
